Which of the following statements is true about quality management?

• Quality control focuses on following proper processes to ensure quality.

• Quality assurance is mainly concerned with the final product quality.

• Testing is an example of a quality assurance activity.

• QA focuses on processes, while QC focuses on products.

Which of the following best describes the relationship between error, defect, and failure?

• A defect causes an error, which leads to failure.

• An error leads to a defect, which may cause a failure.

• A failure creates a defect, which results in an error.

• A defect is an event; a failure is a state in the software.

What is the main goal of left-shift testing in software development?

• To reduce the number of testers needed

• To delay testing until the final release

• To find defects earlier in development

• To focus only on user acceptance testing

Which of the following is NOT a common reason why errors occur in software development?

• Human fallibility

• Time pressure

• Perfect system design

• Miscommunication

Which of the following is one of the seven testing principles?

• Testing can prove that the software is completely error-free.

• Exhaustive testing is always possible and necessary.

• Most defects are in a small number of modules.

• The more you test, the more defects you will always find.

What is the main purpose of software testing?

• To prove the software has no defects

• To show the presence of defects

• To ensure 100% code coverage

• To delay the release

Why is exhaustive testing not feasible?

• Because software is always perfect

• Testing all input combinations is impractical

• Because testers are not skilled enough

• Because requirements are always unclear

When should testing activities ideally begin?

• After development is complete

• During the deployment phase

• As early as possible in the lifecycle

• Only after system testing

What does "defect clustering" mean?

• All modules have equal defects

• Most defects are found in a few modules

• Defects are evenly spread

• Defects appear randomly

What is the "pesticide paradox" in testing?

• The same tests always find a lot of new bugs

• Repeating tests finds fewer new defects

• Bugs are immune to testing

• Testing is harmful to software
