Software Testing MCQs

Which principle of testing says defects are often concentrated in a few modules?

• Absence-of-errors fallacy

• Pesticide paradox

• Defect clustering

• Early testing

Running the same test cases repeatedly will find fewer new bugs. This is called:

• Defect clustering

• Pesticide paradox

• Early testing

• Exhaustive testing

Even if software is error-free, it may still fail to meet user needs. This refers to:

• Exhaustive testing

• Absence-of-errors fallacy

• Defect clustering

• Context-dependent principle

Early testing is important because:

• Prevents regression

• Improves UI

• Fixing defects early is cheaper

• Increases complexity

Which principle states exhaustive testing is impossible?

• Complete testing is not feasible

• Defect clustering

• Pesticide paradox

• Absence-of-errors fallacy

Verification checks if the product is built ___, Validation checks if the right product is built.

• Incorrectly

• Correctly

• Slowly

• With bugs

Which activity is part of validation?

• Code walkthrough

• User Acceptance Testing

• Static review

• Code inspection

Which is part of verification?

• Reviews and walkthroughs

• Beta testing

• System testing

• Alpha testing

Validation ensures:

• Product follows standards

• Product meets user requirements

• Code is fully covered

• Bugs are fixed

Verification is usually done by:

• Developers and testers internally

• End-users

• Customers

• Operators
