Branch coverage is a type of structural coverage metric that measures the percentage of branches or decision outcomes that are executed by the test cases. A branch is a point in the code where the control flow can take two or more alternative paths based on a condition. For example, an if-else statement is a branch that can execute either the if-block or the else-block depending on the evaluation of the condition. Branch coverage ensures that each branch is taken at least once by the test cases, and thus reveals the behavior of the software under different scenarios. Branch coverage is also known as decision coverage or all-edges coverage.

Branch coverage is suitable for testing the cases where a specific action is not allowed, because it can verify that the test cases cover all the possible outcomes of the conditions that determine the action. For example, if the program has a condition that checks if the manufacturing stage can be stopped, then branch coverage can ensure that the test cases cover both the cases where the stage can be stopped and where it cannot be stopped. This way, branch coverage can help identify any missing or incorrect branches that may lead to undesired or unsafe actions.

The other options are not correct because they are not suitable for testing the cases where a specific action is not allowed. Code coverage is a general term that encompasses various types of coverage metrics, such as statement coverage, branch coverage, data flow coverage, etc. Code coverage does not specify which type of coverage metric is used for the analysis. Data flow coverage is a type of structural coverage metric that measures the percentage of data flow paths that are executed by the test cases. A data flow path is a sequence of statements that define, use, or kill a variable. Data flow coverage is useful for testing the correctness and completeness of the data manipulation in the software, but not for testing the conditions that determine the actions. Statement coverage is a type of structural coverage metric that measures the percentage of statements or lines of code that are executed by the test cases. Statement coverage ensures that each statement is executed at least once by the test cases, but it does not reveal the behavior of the software under different scenarios. Statement coverage is a weaker criterion than branch coverage, because it does not account for the branches or decision outcomes in the code. References = ISTQB Certified Tester Foundation Level (CTFL) v4.0 syllabus, Chapter 4: Test Techniques, Section 4.3: Structural Testing Techniques, Pages 51-54.

In the V-model project described in the question, the tester can identify the following based on the provided information:

Expected result (II):The requirements specification clearly states that the app should only ask for access permissions to the camera and photos stored on the device during and after installation. This expected behavior is defined by the requirements.

Actual result (III):The tester observes that the app also requests access to all contacts on the device, which deviates from the expected result. This actual observation can be recorded accurately.

Given these details, the tester can specify the expected result (II) and the actual result (III) in the defect report. However, without more information, the tester cannot determine the test environment (I), the test level (IV), or the root cause (V).

This answer is correct because equivalence partitioning is a test design technique that divides the input domain of a system or component into partitions of equivalent data, such that each partition is expected to produce the same output or behavior. Equivalence partitioning aims to reduce the number of test cases by selecting one representative value from each partition. In this case, the input domain of the TAS can be divided into four partitions based on the bonus rules: less than 50k€, between 50k€ and 80k€, between 80k€ and 120k€, and more than 120k€.The test cases in the answer belong to the same partition, which is between 80k€ and 120k€, and they are expected to produce the same output, which is a bonus of 15%. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.3.2.1

A configuration management tool helps in maintaining and managing changes to software, including test cases. It ensures that changes are tracked and can be retrieved if needed. In this scenario, using a configuration management tool would have allowed Sam's updates to be stored in a central repository, preventing the loss of his work even if his PC's hard disk crashed.

The whole team approach in testing means that the responsibility for testing is shared among all members of the team, not just the testers. This concept is emphasized in agile methodologies where collaboration and collective ownership of quality are key principles. Each team member, including developers, business analysts, and testers, contributes to the testing process, ensuring that quality is built into the product from the beginning.

Atest planis amanagement documentthat outlines thescope, objectives, schedule, resources, and risksof the testing process. Thebudget and schedule (A)are essential components as they help plan resources and timeline constraints.

(B) is incorrectbecause defect analysis is part of thetest summary report, not the test plan.

(C) is incorrectbecausefinal reports summarize execution, while the test plan is createdbefore testing starts.

(D) is incorrectbecause test logs areexecution artifactsrather than planning elements.

A test planguides testing activities and ensures alignment with project objectives.

Exhaustive testing (testing all input combinations) is practically impossible except in trivial cases (C). Instead, testers focus on risk-based, prioritized, and efficient test techniques. The seven principles of testing in the ISTQB syllabus highlight that exhaustive testing is infeasible, and therefore, techniques such as equivalence partitioning, boundary value analysis, and risk-based testing are used to optimize test coverage.

Test automationimproves efficiency and accuracy, butit does NOT eliminate manual testing (D).

(A) is correctbecause automationspeeds up execution.

(B) is correctas automated tests produceconsistent and unbiased results.

(C) is correctbecause automationreduces human errors in repetitive tests.

However,manual testing remains essential for exploratory testing, usability testing, and complex test scenarios.

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.

A factor that contributes to a successful review is ensuring that all participants are trained to understand the review type and its objectives. This training helps participants to effectively contribute to the review process, identify issues, and suggest improvements. Proper training also fosters a constructive and collaborative review environment.
