In branch testing, a conditional branch represents a decision point in the software program where the flow of execution can take different paths based on specific conditions. For example, this could be an "if-else" statement, a "switch-case" statement, or loops where different execution paths are taken depending on the evaluated condition. This type of testing ensures that all possible paths and conditions are executed at least once, which helps in identifying any potential defects in different branches of the code​​.

The three-point test estimation technique is a method of estimating the test effort based on three initial estimates: the most optimistic, the most likely, and the most pessimistic. The technique uses a weighted average of these three estimates to calculate the final estimate, which is also known as the expected value. The formula for the expected value is:

Expected value = (most optimistic + 4 * most likely + most pessimistic) / 6

Using the given values, the expected value is:

Expected value = (6 + 4 * 30 + 54) / 6 Expected value = 30 person hours

However, the expected value is not the only factor to consider when estimating the test effort. The technique also calculates the standard deviation, which is a measure of the variability or uncertainty of the estimates. The formula for the standard deviation is:

Standard deviation = (most pessimistic - most optimistic) / 6

Using the given values, the standard deviation is:

Standard deviation = (54 - 6) / 6 Standard deviation = 8 person hours

The standard deviation can be used to determine a range of possible values for the test effort, based on a certain level of confidence. For example, using a 68% confidence level, the range is:

Expected value ± standard deviation

Using the calculated values, the range is:

30 ± 8 person hours

Therefore, the final estimate is between 22 person hours and 38 person hours, which is option A.

Test execution involves running test cases and documenting results. Test logs (A) provide evidence of executed tests, failures, and actual outcomes. Automated test scripts (B) are part of test implementation, test plans (C) belong to test planning, and test conditions (D) are identified during test analysis.

Debugging activities typically include reproducing the failure, diagnosing the root cause, and fixing the cause of the failure. Adding new test cases, while important in the overall testing process, is not a direct part of debugging. Debugging focuses on understanding and correcting the issue that caused the failure, rather than expanding the test suite.

A test status report communicates the current status, progress, and issues encountered during testing to stakeholders. It is crucial for effective test management and decision-making.

Option A:Correct as it involves reporting impediments and solutions, which are essential for ongoing test activities.

Option B:Incorrect because test status reports are not limited to test completion activities and focus more on ongoing test status rather than final unmitigated risks.

Option C:Incorrect as the structure and contents of reports should be tailored to the audience's needs to ensure effective communication.

Option D:Incorrect because specifying communication lines is typically done in the test plan, not the status report.

Thus, option A best describes a key aspect of a test status report.

This answer is correct because code-related white-box test techniques are test design techniques that use the structure of the code to derive test cases. They provide an objective measure of coverage, such as statement coverage, branch coverage, or path coverage, which indicate how much of the code has been exercised by the test cases. Code-related white-box test techniques can be used to complement black-box test techniques, which are test design techniques that use the functional or non-functional requirements of the system or component to derive test cases. By combining both types of techniques, testers can increase their confidence in the code and find more defects. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.3.2.2

The statement "Achieving full code coverage for a component or a system ensures that it has been fully tested" is false because achieving full code coverage does not necessarily mean that all possible defects have been identified or that the system is free of bugs. Code coverage metrics, such as statement coverage, branch coverage, or path coverage, only measure the extent to which the source code has been executed during testing, but they do not guarantee that all logical paths or use cases have been exercised or that the code behaves correctly under all conditions.

Full code coverage indicates that every line of code has been executed at least once, but it does not account for the quality of the test cases or their ability to detect defects. There can still be issues related to performance, usability, security, and other non-functional aspects that are not addressed by code coverage alone.

Checklist-based testing, as defined in the ISTQB CTFL syllabus, is indeed a review technique used within formal review processes. During these reviews, reviewers individually inspect work products to identify defects based on predefined checklists. These checklists serve as guidelines to ensure thorough examination and to cover important aspects consistently.

The other options do not accurately describe the checklist-based testing technique. Option A describes a technique for managing review meetings rather than the checklist-based testing itself. Option C incorrectly emphasizes the level of detail in checklists as a factor in reproducibility of test cases, which is not the primary focus of checklist-based testing. Option D, while true about the necessity of periodic review, is not the core aspect of the checklist-based testing technique itself.

Acceptance criteria8states thatthe system should charge the user on the first business day of the following month. However, thetest cycle only verified monthly payments for over a year, without confirming whether payments were processedspecifically on the first business day.

(B) is incorrectbecause the test validatedmonthly and annual payment options.

(C) is incorrectbecause not all criteria were fully validated.

(D) is incorrectbecause OTP verification (6) was tested as part of registration.

Ensuringtimely execution of payments(Criteria 8) requires additional validation.

Static analysis is the process of examining the work products of a software development or testing activity without executing them. Static analysis can be applied to various types of work products, such as requirements, design, code, test cases, etc. However, test plans are not suitable for static analysis, because they are high-level documents that describe the test objectives, scope, strategy, resources, schedule, and risks of a testing project. Test plans are not executable or formalized in a way that static analysis tools can analyze them. Therefore, option A is the correct answer.
