QUESTION 15
A program got 100% decision coverage in a test. Which of the following statements is then guaranteed to be true?

Every executable statement Is covered.

Every output equivalence class has been tested.

Every input equivalence class has been tested.

The “dead” code has not been covered.

If a program got 100% decision coverage in a test, then it is guaranteed that every executable statement is covered. Decision coverage (also known as branch coverage) is a type of structural coverage (also known as white-box coverage) that measures how many decision outcomes have been exercised by a test suite. A decision outcome is a possible result of a decision point (such as an if-then-else statement) in a program’s code. Decision coverage requires that each decision point has both true and false outcomes executed at least once by a test suite. Decision coverage implies statement coverage, which is another type of structural coverage that measures how many executable statements have been executed by a test suite. Statement coverage requires that each executable statement is executed at least once by a test suite. Therefore, if a program got 100% decision coverage in a test, then it also got 100% statement coverage in a test, which means that every executable statement is covered. The other options are not guaranteed to be true if a program got 100% decision coverage in a test. Every output equivalence class has been tested and every input equivalence class has been tested are not guaranteed to be true if a program got 100% decision coverage in a test, because equivalence classes are based on functional requirements or specifications, not on code structure or logic. Equivalence classes are used in specification-based testing (also known as black-box testing), which is a type of testing that does not consider the internal structure or implementation of the system under test. Decision coverage is used in structure-based testing (also known as white-box testing), which is a type of testing that considers the internal structure or implementation of the system under test. Therefore, achieving 100% decision coverage does not imply achieving 100% equivalence class coverage. The “dead” code has not been covered is not guaranteed to be true if a program got 100% decision coverage in a test, because dead code (also known as unreachable code) is code that can never be executed due to logical errors or design flaws. Dead code can reduce readability and maintainability of the code, as well as increase complexity and size. Decision coverage does not account for dead code, as it only considers the decision outcomes that are possible to execute. Therefore, achieving 100% decision coverage does not imply that the dead code has not been covered. Verified Reference: A Study Guide to the ISTQB Foundation Level 2018 Syllabus – Springer, page 36.

QUESTION 16
Which of the following statements about re-testing and regression testing are TRUE?
I Re-testing should be performed after a defect is fixed.
II Regression testing should always be performed after a defect is fixed.
III Re-testing and regression testing may be performed at any test level.
IV Regression testing may include functional, non-functional and structural testing.
V Re-testing should be included in the debugging activity.

I, III. Iv

II, v

I, Ill

II. IV, V

The following statements about re-testing and regression testing are true:
I) Re-testing should be performed after a defect is fixed. Re-testing is a type of testing that verifies that a defect has been successfully resolved by executing a test case that previously failed due to that defect. Re-testing should be performed after a defect is fixed and delivered to ensure that it does not cause any new failures or side effects.
III) Re-testing and regression testing may be performed at any test level. Re-testing and regression testing are not limited to a specific test level, but can be applied at any level depending on the context and objectives. For example, re-testing and regression testing can be performed at unit level, integration level, system level or acceptance level.
IV) Regression testing may include functional, non-functional and structural testing. Regression testing is a type of testing that verifies that previously tested software still performs correctly after changes. Regression testing may include various types of testing depending on the scope and purpose of the changes. For example, regression testing may include functional testing to check if the software meets its requirements, non-functional testing to check if the software meets its quality attributes, or structural testing to check if the software meets its design or code standards. The following statement about re-testing and regression testing is false:
II) Regression testing should always be performed after a defect is fixed. Regression testing is not always necessary after a defect is fixed, as some defects may have a low impact or low likelihood of affecting other parts of the software. Regression testing should be performed after a defect is fixed only if there is a risk of introducing new defects or causing existing defects due to the changes made to fix the defect.

QUESTION 17
A mid-size software product development company has analyzed data related to defects detected in its product and found out that detects fixed in earlier builds are getting re-opened after a few months.
The company management now seeks your advice in order to reverse this trend and prevent re-opening of defects fixed earlier.
What would be your FIRST recommendation to the company?

Automate existing test suits so that lesser time is spent on execution of each test, and more tests can be executed m the available time thus leading to a lower probability of defects slipping by

Verify existing regression test suite are adequate, and augment it, if required, in order to ensure that defects fixed earlier get re-tested in each subsequent build

Analyze the product modules containing maximum defects, and get them thoroughly tested and defects fixed as a one-time activity

If required, tram the teams responsible for development and testing of the modules containing maximum number of defects, and if this does not help, replace them with more knowledgeable people

QUESTION 25
In what way do Configuration Management effects testing?

Without proper configuration management, test planning cannot proceed.

Proper configuration management ensures that testers can uniquely identity the tested item

Configuration management is important for developers, not for testers

There is very little influence of configuration management practices on the test project.

QUESTION 26
The following sentences refer to the ‘Standard for Software Test Documentation’ specification (IEEE 829).
Which sentence is correct?

Any deviation from this standard should be approved by management, marketing & development

Most test documentation regimes follow this spec to some degree, with changes done to fit a specific situation or organization

The key to high quality test documentation regimes is strict adherence to this standard

This test plan outline is relevant for military projects. For consumer market projects there is a different specification with fewer items.

II, IV

Testware is a term that refers to all artifacts produced during the testing process, such as test plans, test cases, test scripts, test data, test results, defect reports, etc. The following statements about testware are correct:
II) All the testware should be subject to Configuration Management. Configuration management is a process that establishes and maintains consistency among work products throughout their life cycle. Configuration management applies to all testware, as it helps ensure their quality and consistency, track their changes and defects, control their versions and access rights, and link them to other artifacts.
III) The testware at the end of the project should be transferred to the organization responsible for maintenance. Maintenance testing is testing performed on a software product after delivery to correct defects or improve performance or other attributes. Maintenance testing requires testware from previous testing activities or phases, such as test cases, test data, test results, etc. Therefore, the testware at the end of the project should be transferred to the organization responsible for maintenance testing, such as support team or maintenance team. The following statements about testware are incorrect:
I) When closing the test activities, all the testware resources can be uninstalled and released. This statement is incorrect, as some testware resources may still be needed for future testing activities or phases, such as maintenance testing or regression testing. Therefore, when closing the test activities, some testware resources should be archived and stored for future use, while others can be uninstalled and released.
IV) The developers are responsible for the correct installation of the testware. This statement is incorrect, as the testers are responsible for the correct installation of the testware. The testers should ensure that they have access to all necessary testware resources and that they are installed and configured properly before starting the test execution.
