NEW QUESTION # 104
The following user story has been written:
As a paying hotel guest
I want to see the charges that have been added to my bill
So that I can monitor my expenditure and know In advance how much I will have to pay when I check out The notes that have been added to It mention that It must be possible for the guest to get a printout of the bill, see It In a variety of currencies and set a flag in the hotel's billing system against any Item that they wish to challenge.
The following acceptance criteria have been defined:
1.The user shall be able to choose from the most commonly-used currencies.
2.The application must be accessible on most mobile platforms as well as on the hotel room's smart TV.
3.The hotel manager must be notified whenever a bill item is flagged by a hotel guest.
4.End-to-end response time for any individual request submitted by a user must not exceed 7 seconds.
Applying the INVEST technique to this user story, including its acceptance criteria, which of the following statements is correct?
SELECT ONE OPTION
- A. The INVEST criteria have all been satisfied by this epic
- B. The Negotiable and Small criteria of INVEST have not been satisfied
- C. The Testable and Small criteria of INVEST have not been satisfied
- D. The Testable and Negotiable criteria of INVEST have not been satisfied
Answer: C
Explanation:
According to the INVEST criteria, the Testable and Small criteria have not been satisfied for the user story provided. Option B is correct.
* INVEST Criteria: The INVEST model stipulates that user stories should be Independent, Negotiable, Valuable, Estimable, Small, and Testable.
* Analysis of the User Story: The scope of the user story and its acceptance criteria suggests it is too broad (thus not 'Small') and the details provided, especially regarding response times and system notifications, imply potential challenges in effectively testing the story (thus possibly not 'Testable') without further refinement or breaking down the story into smaller, more manageable pieces.
The size and complexity of the requirements indicate that the story might be better classified as an epic, needing decomposition into smaller, more specific user stories that can be more feasibly addressed within agile iterations .
NEW QUESTION # 105
The last release of a hotel booking website resulted in poor system performance when hotel searches reached peak volumes. To address these problems in the forthcoming release, changes to the system architecture are to be implemented as follows:
Change 1 - Provision of a single Internet service using multiple servers, rather than a single server, to maximize throughput and minimize response time during peak volumes Change 2 - Prevention of unnecessary database calls for objects that were not immediately needed by the calling applications. Achieved by not automatically creating database connections at the start of processing, instead only just before the data is required.
The system architecture document has been drafted and as Technical Test Analyst you have been invited to participate in its review. Which of the following review checklist items is MOST likely to identify any defects in the proposed system architecture for Change 2?
- A. Connection pooling
- B. Lazy instantiation
- C. Data replication
- D. Caching
Answer: B
Explanation:
Analysis:
For Change 2, the goal is to prevent unnecessary database calls by delaying the creation of database connections until they are actually needed. This approach is known as lazy instantiation.
C: Lazy instantiation:
* Lazy instantiation is a design pattern that defers the creation of an object until the point at which it is needed. This can help improve performance by reducing unnecessary resource consumption. In the context of database connections, it ensures that connections are only established when required, thus avoiding unnecessary overhead.
Explanation of Incorrect Options:
* A. Connection pooling:
* Connection pooling involves reusing database connections from a pool rather than creating new ones each time. While this improves efficiency, it does not specifically address the issue of deferring database connections until needed.
* B. Data replication:
* Data replication refers to copying data across multiple databases to ensure consistency and availability. It is not directly related to managing when database connections are established.
* D. Caching:
* Caching involves storing frequently accessed data in memory to improve retrieval times. While beneficial for performance, it does not address the specific issue of delaying database connections.
References:
The ISTQB CTAL-TTA syllabus and standard software architecture practices highlight the importance of design patterns such as lazy instantiation for optimizing resource usage and performance.

NEW QUESTION # 106
Given the following code:
If x > y and z = 3 statement!
elself z = 4
statement2
endif;
What is the minimum number of tests needed to achieve 100% statement coverage?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
To achieve 100% statement coverage, you need to ensure every executable statement in the code is executed at least once during testing. Given the code:
If x > y and z = 3 statement1 elseif z = 4 statement2 endif;
Two tests are required:
* Test 1: Set x > y and z = 3 to execute statement1.
* Test 2: Set z = 4 (irrespective of the condition x > y) to execute statement2.
With these two tests, both conditions that lead to the execution of statement1 and statement2 are covered.
NEW QUESTION # 107
Given the following pseudocode:
Program tax check
BEGIN
yearly := 0
tax := 0
get (monthly)
get (tax_rate)
for I = 1..12 loop
yearly := yearly + monthly
tax := tax - (tax_rate * monthly)
ENDLOOP
salary := monthly * 12
IF salary = yearly THEN
print ("Salary OK")
ELSE
print ("Salary not OK")
ENDIF
year_tax := salary * tax_rate
IF year_tax = tax THEN
print ("Tax Problem")
ENDIF
END tax check
If control flow analysis is performed on the pseudocode, which of the following results is MOST likely?
- A. No unreachable code
- B. Unreachable code at line 15
- C. Unreachable code at line 19
- D. Unreachable code at lines 15 and 19
Answer: C
Explanation:
Control flow analysis is a technique used to examine the sequence in which instructions or statements are executed within a program. In the given pseudocode, the key aspects to consider are the logical flow and any conditional branches that may lead to unreachable code.
The pseudocode provided is:
Program tax check
BEGIN
yearly := 0
tax := 0
get (monthly)
get (tax_rate)
for I = 1..12 loop
yearly := yearly + monthly
tax := tax - (tax_rate * monthly)
ENDLOOP
salary := monthly * 12
IF salary = yearly THEN
print ("Salary OK")
ELSE
print ("Salary not OK")
ENDIF
year_tax := salary * tax_rate
IF year_tax = tax THEN
print ("Tax Problem")
ENDIF
END tax check
Analysis:
* Initialization and Input:yearly and tax are initialized to 0. The program takes monthly and tax_rate as
* input.
* Loop Execution:The loop runs from 1 to 12, accumulating monthly into yearly and adjusting tax accordingly.
* Salary Calculation and Check:After the loop, salary is calculated as monthly * 12. The program then checks if salary is equal to yearly. Given the loop accumulates monthly into yearly 12 times, salary will always equal yearly, making the IF salary = yearly condition always true. Thus, the "Salary OK" message will always be printed, and the ELSE branch will never be executed.
* Yearly Tax Calculation and Check:year_tax is calculated as salary * tax_rate. Then, it checks if year_tax is equal to tax. However, due to the accumulation and subtraction inside the loop, tax would likely not equal year_tax, making the condition IF year_tax = tax false in most practical scenarios.
Therefore, the "Tax Problem" message at line 19 is unlikely to be printed.
Conclusion:
Given this flow, the ELSE block associated with the IF salary = yearly condition (line 15) is unreachable.
However, the critical analysis indicates that the code at line 19, which prints "Tax Problem", is also unreachable due to the logic flow where the condition is rarely true.
Thus, the result is that line 19 is more certainly unreachable.
NEW QUESTION # 108
Consider the pseudo code for the Price program:
Which of the following statements about the Price program describes a control flow anomaly to be found in the program?
- A. The Price program contains an infinite loop.
- B. The Price program contains unreachable code.
- C. The Price program contains data flow defects.
- D. The Price program contains no control flow anomalies.
Answer: A
Explanation:
The pseudo code provided for the Price program shows a potential for an infinite loop due to the way the
'Del_Charge' variable is being manipulated. The loop is set to continue 'WHILE Del_Charge > 0', and within the loop, 'Del_Charge' is initially set to 5 and then potentially decreased by 2 if 'Sale_Value > 60000'.
However, at the end of each loop iteration, 'Del_Charge' is increased by 1. This means that if 'Sale_Value' is not greater than 60000, 'Del_Charge' will not decrease and will instead increment indefinitely, causing an infinite loop. Even if 'Sale_Value' is greater than 60000, the decrement by 2 could be negated by the subsequent increments if the loop runs enough times, potentially leading to an infinite loop situation. There is no guaranteed exit condition once the loop is entered, which is a control flow anomaly.
NEW QUESTION # 109
A new system is being built to handle the message handling of financial transactions - this system is critical to the organization's finances. The code includes loops and decisions with several multiple conditions. The nature of the system means that tests are quite time-consuming to execute. Which of the following would be the BEST white box testing option for the new software?
- A. Statement coverage
- B. Multiple Condition coverage
- C. MC/DC coverage
- D. Decision coverage
Answer: C
Explanation:
In a critical system that handles financial transactions with complex logic, ensuring thorough testing coverage is crucial. Here's an analysis of the options:
* A. Multiple Condition coverage: This provides the highest level of coverage by testing all possible combinations of conditions. However, it can be very time-consuming and is often impractical for complex systems due to the sheer number of test cases required.
* B. MC/DC coverage: Modified Condition/Decision Coverage is a compromise between multiple condition coverage and decision coverage. It ensures that each condition within a decision has been shown to independently affect the outcome of that decision. This level of coverage is often required in safety-critical systems because it provides thorough testing without the excessive test case count of multiple condition coverage.
* C. Decision coverage: This ensures that every decision (if statement) has been executed in both true and false directions. While useful, it may not be sufficient for complex systems where the interactions between conditions are critical.
* D. Statement coverage: This ensures that every executable statement in the code has been executed. It is the most basic level of coverage and is generally not sufficient for complex systems, especially those that are critical to an organization's finances.
Given the critical nature of the system and the need for a balance between thoroughness and practicality, the best option is B. MC/DC coverage. This ensures a high level of coverage that is more practical than multiple condition coverage while providing more assurance than decision or statement coverage.
NEW QUESTION # 110
Given the following pseudocode:
Program tax check
Integer: tax_rate
real: tax%
BEGIN
tax% := 0
GET (tax_rate)
WHILE tax_rate > 0 loop
IF tax_rate > 3 THEN
tax_rate := 3
ENDIF
tax% := tax% + (tax_rate / 10)
tax_rate := tax_rate - 1
ENDLOOP
IF tax% > 0.6 THEN
print ("tax rate is high")
ELSEIF tax% < 0.1 THEN
print ("tax rate is zero")
ELSE
print ("tax rate is low")
ENDIF
END tax check
If control flow analysis is performed on the pseudocode, which of the following results is MOST likely?
- A. No unreachable code
- B. Unreachable code at line 15
- C. Unreachable code at line 17
- D. Infinite loop from line 7 to line 13
Answer: C
Explanation:
Program tax check
Integer: tax_rate
real: tax%
BEGIN
tax% := 0
GET (tax_rate)
WHILE tax_rate > 0 loop
IF tax_rate > 3 THEN
tax_rate := 3
ENDIF
tax% := tax% + (tax_rate / 10)
tax_rate := tax_rate - 1
ENDLOOP
IF tax% > 0.6 THEN
print ("tax rate is high")
ELSEIF tax% < 0.1 THEN
print ("tax rate is zero")
ELSE
print ("tax rate is low")
ENDIF
END tax check
Explanation of Control Flow:
* Initialization:
* tax% := 0
* Get Tax Rate:
* GET (tax_rate)
* While Loop:
* Loop runs while tax_rate > 0.
* Inside the loop:
* If tax_rate > 3, set tax_rate to 3.
* Update tax% by adding tax_rate / 10.
* Decrement tax_rate by 1.
* Post-Loop Condition Checks:
* After the loop, check the value of tax%:
* If tax% > 0.6, print "tax rate is high".
* Else if tax% < 0.1, print "tax rate is zero".
* Otherwise, print "tax rate is low".
Unreachable Code Analysis:
* The ELSEIF tax% < 0.1 THEN condition (line 17) is unreachable.
* In the loop, tax% is incremented by a minimum of 0.1 each time tax_rate is greater than 0.
* Therefore, tax% cannot be less than 0.1 after the loop.
Conclusion:
* Line 17 (ELSEIF tax% < 0.1 THEN) will never be true given the logic of the loop.
NEW QUESTION # 111
Assume you are involved in testing a Health Insurance Calculation system.
At the main screen one can enter information for a new client. The information to be provided consists of last name, first name and date of birth. After confirmation of the information, the system checks the age of the potential new client and calculates a proposed premium.
The system also has the option to request information for an existing client, using the client's ID number.
A keyword-driven automation approach is being used to automate most of the regression testing.
Based on the information provided, which TWO of the options provided would be the MOST LIKELY keywords for this application? (Choose two.)
- A. Remove_Client
- B. Print_Premium
- C. Exclude_Client
- D. Enter_Client
- E. Select_Client
Answer: D,E
Explanation:
Considering the functionalities described for the Health Insurance Calculation system, the keywords would represent the main actions that can be performed in the system. 'Enter_Client' would be a keyword for entering new client information, which is a primary feature of the system as described. 'Select_Client' would be used to retrieve information for an existing client using the client's ID number, which is another main functionality.
Other options such as 'Remove_Client', 'Print_Premium', and 'Exclude_Client' are not explicitly mentioned in the provided system functionalities, therefore, 'Enter_Client' and 'Select_Client' are the most likely keywords for automation.
NEW QUESTION # 112
The last release of a hotel booking website resulted in poor system performance when hotel searches reached peak volumes. To address these problems in the forthcoming release, changes to the system architecture are to be implemented as follows:
Change 1 - Provision of a single Internet service using multiple servers, rather than a single server, to maximize throughput and minimize response time during peak volumes Change 2 - Prevention of unnecessary database calls for objects that were not immediately needed by the calling applications. Achieved by not automatically creating database connections at the start of processing, instead only just before the data is required.
The system architecture document has been drafted and as Technical Test Analyst you have been invited to participate in its review. Which of the following review checklist items is MOST likely to identify any defects in the proposed system architecture for Change 1?
- A. Connection pooling
- B. Load balancing
- C. Distributed processing
- D. Caching
Answer: B
Explanation:
Analysis:
For Change 1, which involves using multiple servers to maximize throughput and minimize response time, the key concern is how the load is distributed across these servers.
B: Load balancing:
* Load balancing is the process of distributing network or application traffic across multiple servers to ensure no single server becomes overwhelmed. It is crucial for maximizing throughput and minimizing response times, particularly during peak volumes.
Explanation of Incorrect Options:
* A: Connection pooling:
* This is related to managing database connections efficiently but is not directly relevant to distributing web server traffic.
* C: Distributed processing:
* This refers to dividing processing tasks across multiple processors or machines but is not specific to managing web server load.
* D: Caching:
* Caching helps improve performance by storing frequently accessed data in memory, reducing the need to retrieve it from the database, but it does not address load distribution across servers.
References:
The ISTQB CTAL-TTA syllabus and standard practices in reviewing system architecture emphasize the importance of load balancing for managing server traffic and ensuring optimal performance during peak loads.

NEW QUESTION # 113
Which of the following best describes the reason why poorly written code is usually more difficult to maintain than well written code?
- A. It tends to run more slowly, causing performance issues that may be difficult to fix
- B. It tends to have a lot of internal documentation
- C. It tends to be difficult for a developer to locate and accurately fix a problem
- D. It tends to contain security issues that may require maintenance releases
Answer: C
Explanation:
Poorly written code often lacks clarity, consistency, and may not follow best practices, making it harder to understand and maintain. When code is not well-structured or logically organized, identifying the source of bugs or understanding how changes might affect system behavior becomes more difficult. This issue is compounded when developers other than the original author need to work on the code, as they may struggle to interpret the intended functionality and interdependencies without clear, readable code.
NEW QUESTION # 114
A new reusable software component that handles sensor management has been developed. It will be used in manufacturing processes that work at SIL 2 and avionics systems where failure could lead to a "major" incident. The code contains no loops but does contain decisions with multiple conditions. Which of the following would be the BEST structure-based testing option for the new software?
- A. Statement coverage
- B. MC/DC coverage
- C. Decision coverage
- D. API coverage
Answer: B
Explanation:
* Context of the Problem:
* The software component handles sensor management.
* It is used in manufacturing processes that work at SIL 2 and avionics systems.
* Failure could lead to a "major" incident.
* The code contains decisions with multiple conditions and no loops.
* Safety Integrity Level (SIL) 2:
* SIL 2 indicates that the software must adhere to stringent safety standards.
* Avionics systems also require high safety standards due to the potential consequences of failure.
* Testing Options:
* MC/DC (Modified Condition/Decision Coverage):
* MC/DC is essential for high-integrity and safety-critical systems like avionics.
* Ensures each condition in a decision has been shown to independently affect the outcome.
* Required by standards such as DO-178C for avionics software at certain levels.
* API Coverage:
* Focuses on testing the interfaces between components.
* Important but not sufficient alone for high-integrity, safety-critical systems.
* Decision Coverage:
* Ensures that each decision point (i.e., if statements) is evaluated as both true and false.
* Less comprehensive than MC/DC for safety-critical applications.
* Statement Coverage:
* Ensures that each statement in the code has been executed at least once.
* Basic level of coverage, insufficient for safety-critical systems like those at SIL 2.
* Best Option:
* Given the high safety requirements (SIL 2, major incident potential), MC/DC coverage is the best option. It provides a thorough level of testing needed to meet safety standards.
NEW QUESTION # 115
Consider the following code segments.
Segment 1:
If a > b then setc = 12
elseif c >7 set c = 5
endif
Segment 2: setc= 12 for n = 1 to c
display c
endfor
Segment 3:
If (a > b) or (c < d) then
set c = 12
else
set c = 5
endlf
Segment 4:
set y = 4
call (segments)
segments:
start
for I = 1 to y
print y
endfor
end
Which segment would receive the highest cyclomatic complexity value?
- A. Segment 3
- B. Segment 2
- C. Segment 1
- D. Segment 4
Answer: A
Explanation:
Cyclomatic complexity is a measure of the number of linearly independent paths through a program's source code. Segment 3 has two conditions: if (a > b) or (c < d) and the associated else. This structure introduces multiple decision points, thereby increasing the number of potential execution paths. Comparatively, the other segments have fewer conditions and straightforward loops, which contribute to a lower cyclomatic complexity.
Segment 3, with its compound condition and branching logic, likely has the highest cyclomatic complexity.

NEW QUESTION # 117
Consider the pseudo code provided below:
Given the following tests, what additional test(s) (if any) would be needed in order to achieve 100% statement coverage, with the minimum number of tests?
Test 1: A = 7, B = 7, Expected output: 7
Test 2: A = 7, B = 5, Expected output: 5
- A. No additional test cases are needed to achieve 100% statement coverage.
- B. A=7, B=9, Expected output: 7
- C. A=6, B=12, Expected output: Bingo! and A=7, B=9, Expected output: 7
- D. A=6, B=12, Expected output: Bingo!
Answer: A
Explanation:
100% statement coverage means that every line of code is executed at least once during testing. Based on the provided pseudo-code and the test cases given:
* Test 1 executes the MIN = B statement when A and B are equal.
* Test 2 executes the MIN = A statement and skips the inner IF since B is not equal to 2*A.
All statements within the code have been executed by these two tests, hence no additional test cases are needed to achieve 100% statement coverage.

NEW QUESTION # 119
Which of the following is a common technical issue that causes automation projects to fail to meet the planned return on investment?
- A. Designing for keyword-driven use
- B. Using capture-playback to do the initial capture of the window objects
- C. Failing to design for maintainability
- D. Insufficient planning for usability
Answer: C
Explanation:
A common technical issue causing automation projects to fail in delivering the planned return on investment is the lack of maintainability in their design. Automation frameworks and scripts that are not designed with maintainability in mind can become cumbersome to update and scale as the software evolves. This results in increased costs and effort over time to keep the automation relevant and effective, which can erode the expected returns on investment from the automation initiative .
NEW QUESTION # 120
Considering the following statements:
A) The data used for a test is held external to the automated script
B) The scope of an automated test suite is driven by the range of test data available C) It uses a high-level language to separate the action to be performed on the test data from the test script D) A spreadsheet is used to record the actions to be performed instead of the input data Which of the following options is the correct selection of these statements to describe data-driven and keyword-driven automation?
- A. Data Driven = a; Keyword-driven = d
- B. Data Driven = b; Keyword-driven = c
- C. Data Driven = d; Keyword-driven = d
- D. Data Driven = a; Keyword-driven = c
Answer: D
Explanation:
Analysis:
Understanding the characteristics of data-driven and keyword-driven automation is crucial for identifying the correct statements.
Correct Pairing:
C: Data Driven = a; Keyword-driven = c:
* Data Driven = a: "The data used for a test is held external to the automated script" is a key characteristic of data-driven testing, where test data is stored separately from the test scripts, allowing the same script to run with different data sets.
* Keyword-driven = c: "It uses a high-level language to separate the action to be performed on the test data from the test script" is characteristic of keyword-driven testing, where keywords representing actions are used to describe test steps, separating the business logic from the test scripts.
Explanation of Incorrect Options:
* A. Data Driven = a; Keyword-driven = d: Statement d does not accurately describe keyword-driven testing.
* B. Data Driven = b; Keyword-driven = c: Statement b does not accurately describe data-driven
* testing.
* D. Data Driven = d; Keyword-driven = d: Statement d is not accurate for either data-driven or keyword-driven testing.

Which of the following issues should be detected in the code review?
- A. Variables are used before they are initialized
- B. Loop termination is not achievable
- C. Some of the code could be moved to re-usable functions
- D. Rounding errors on the loop counters could cause problems
Answer: B
Explanation:
The pseudocode provided includes a while loop that adjusts the loop variable a within the loop's conditional code block. This adjustment, set a = 5, occurs when a > 10. Because the loop checks a < 12 as its continuation condition, and a is reset to 5 repeatedly once it exceeds 10, the loop will execute indefinitely, preventing termination. This creates an infinite loop situation since the condition a < 12 will perpetually remain true once a exceeds 10. This is a critical logic error needing correction for proper execution flow.
NEW QUESTION # 122
You are a Technical Test Analyst preparing load test scripts. You have been invited to a technical review of the system's operational profile document produced by the business.

- A. To avoid delay to the project, attend the review as scheduled and raise the issue at the meeting
- B. Request that the meeting be delayed until the volumetric document has been drafted and examined by the reviewers
- C. Delay the review but limit schedule impact by presenting the volumetric document to the reviewers during the meeting
- D. State that you are not a mandatory reviewer but request that both documents be sent to you once agreed
Answer: A
Explanation:
Analysis:
When faced with incomplete documentation during test preparation, it is important to balance the need for thoroughness with the need to maintain project schedules.
B: To avoid delay to the project, attend the review as scheduled and raise the issue at the meeting:
* This option ensures that the review proceeds as planned, preventing project delays. By raising the issue during the meeting, you can highlight the importance of the missing volumetric data and ensure it is addressed promptly.
Explanation of Incorrect Options:
* A: Request that the meeting be delayed until the volumetric document has been drafted and examined by the reviewers:
* Delaying the meeting might cause project delays and may not be necessary if the issue can be addressed in the meeting.
* C: State that you are not a mandatory reviewer but request that both documents be sent to you once agreed:
* This might cause you to miss important discussions in the review meeting.
* D: Delay the review but limit schedule impact by presenting the volumetric document to the reviewers during the meeting:

NEW QUESTION # 123
Which option correctly states the sequence of tasks to be undertaken when re-factoring test cases?
SELECT ONE OPTION
- A. Identification, Evaluate, Analysis, Refactor, Re-run
- B. Identification, Analysis, Refactor, Re-run, Evaluate
- C. Evaluate, Identification, Analysis. Re-run, Refactor
- D. Analysis, Identification, Re run, Refactor, Evaluate
Answer: B
Explanation:
The correct sequence of tasks for refactoring test cases is:
* Identification: Recognize the need and potential areas for refactoring.
* Analysis: Assess the impact and dependencies related to the changes.
* Refactor: Make the actual modifications to improve the test cases.
* Re-run: Execute the modified test cases to ensure they still meet the required objectives.
* Evaluate: Assess the outcomes of the refactor to ensure effectiveness and efficiency.
This sequence is supported by the ISTQB documentation, emphasizing the methodical approach needed to efficiently update and improve test cases, ensuring they remain effective and relevant .
NEW QUESTION # 124
Below is pseudo-code which calculates a customer's cruise credits based on past cruise history:
PROGRAM CALC CRUISE CREDITS (CUST_ID)
COUNT_CRUISES, CRUISE_CREDITS, LOYALTY_RATING: INTEGER
CRUISE_LENGTH, CRUISE_ACCOM_TYPE: VAR
LOYALTY_RATING = 0
COUNT_CRUISES = 0
CRUISE_LENGTH = 0
CRUISE_ACCOM_TYPE = 0
BEGIN
READ CUSTOMER'S CRUISE HISTORY TO OBTAIN COUNT OF CRUISES
READ CRUISE_HISTORY (CUST_ID)
WHILE COUNT_CRUISES != -1 DO
READ CUSTOMER'S NEXT CRUISE
READ NEXT_CRUISE
IF CRUISE_ACCOM_TYPE = 3 THEN
CRUISE_CREDITS = CRUISE_CREDITS + 5
ELSE
IF CRUISE_ACCOM_TYPE = 2 THEN
CRUISE_CREDITS = CRUISE_CREDITS + 3
ELSE
CRUISE_CREDITS = CRUISE_CREDITS + 2
ENDIF
ENDIF
COUNT_CRUISES = COUNT_CRUISES - 1
ENDWHILE
LOYALTY_RATING = CRUISE_CREDITS / COUNT_CRUISES
WRITE ("CRUISE CREDIT TOTAL IS:")
WRITE (CRUISE_CREDITS)
END PROGRAM CALC CRUISE CREDITS
The variable Cruise_Length (line 3) results in which type of data flow anomaly?
- A. Killed before being Defined
- B. Defined twice before Use
- C. Declared but not Defined
- D. Defined but not Used
Answer: D
Explanation:
A data flow anomaly occurs when a variable is used in an illogical manner within a program. The anomalies are typically classified into the following categories:
* Defined but not Used (d-u): A variable is assigned a value, but the value is never utilized.
* Declared but not Defined (d): A variable is declared but not given an initial value.
* Killed before being Defined (k-d): A variable is released or nullified before any value is assigned to it.
* Defined twice before Use (d-d): A variable is assigned a value multiple times without being used between definitions.
In the given pseudocode, Cruise_Length is declared at the beginning but it is neither assigned any value (defined) nor used anywhere in the program. This makes it a case of "Defined but not Used".
References:
* This explanation is derived from standard definitions and explanations of data flow anomalies in the context of software testing and static analysis, which are part of the ISTQB CTAL-TTA syllabus and testing principles.
NEW QUESTION # 125
Listed below are some possible findings from static analysis of a component containing approximately 1,000 lines of code. Which combination suggests that the component does NOT need refactoring for better maintainability?
A) Low measure of coupling.
B) Low measure of cohesion.
C) Low measure of commenting.
D) Low measure of complexity.
E) High measure of coupling.
F) High measure of cohesion.
G) High measure of commenting.
H) High measure of complexity.
- A. c, d, h
- B. a, d, h
- C. d, f, h
- D. b, e, g
Answer: C
Explanation:
When evaluating a component for maintainability, several metrics are considered:
* Coupling: Refers to the degree of interdependence between software modules. Lower coupling is preferred for maintainability.
* Cohesion: Refers to how closely related the responsibilities of a single module are. Higher cohesion within modules is preferred.
* Commenting: Refers to the presence of comments within the code. While useful, excessive commenting is not necessarily an indicator of maintainability.
* Complexity: Refers to the complexity of the code, often measured by metrics like cyclomatic complexity. Lower complexity is preferred.
Given these metrics:
* d. Low measure of complexity: Indicates the code is simple and straightforward, which enhances maintainability.
* f. High measure of cohesion: Indicates that modules have clear, well-defined responsibilities, enhancing maintainability.
* h. High measure of complexity: This should generally be low for better maintainability, but in this context, the assumption is an erroneous inclusion in the preferred list.
Thus, the best combination suggesting that the component does NOT need refactoring for better maintainability is d, f, h.
References:
* The selection of metrics and their desired values are based on software engineering principles covered in the ISTQB CTAL-TTA syllabus, which emphasizes low complexity and high cohesion for maintainable software design.
NEW QUESTION # 126
Which of the following defect types is NOT an example of a defect type typically found with API testing?
- A. Loss of transactions
- B. Timing problems
- C. High architectural structural complexity
- D. Data handling issues
Answer: C
Explanation:
In the context of API testing, the defect types generally found are related to the specific interactions with the API, such as issues with data formatting, handling, validation, and the sequencing or timing of API calls.
Architectural structural complexity is not typically a defect that would be identified at the API testing level.
API tests are concerned with the interface and immediate integration points, not the overarching system architecture, which would be more relevant to design or system-level testing.
