ITMC322 QM Prelims Exam

A software development team tests an application extensively but still finds defects after release. This demonstrates which principle of testing?

• Testing shows the presence of defects

• Exhaustive testing is possible

• Defect clustering

• Testing eliminates all risks

The cost of fixing a defect increases the later it is found in the software development life cycle. Which principle of testing does this relate to?

• Pesticide paradox

• Early testing

• Context-dependent testing

• Exhaustive testing is possible

A tester runs the same set of test cases repeatedly and finds no new defects. This is an example of:

• Defect clustering

• Exhaustive testing

• Pesticide paradox

• Context-dependent testing

Not all parts of a system contain defects equally. Which principle states that most defects are found in a few modules?

• Defect clustering

• Early testing

• Absence-of-errors fallacy

• Testing is context dependent

Testing cannot prove that a system is 100% defect-free, only that defects exist. This is an example of which principle?

• Absence-of-errors fallacy

• Testing shows the presence of defects

• Testing is context-dependent

• Early testing

Software developed for an e-commerce site will require different testing than software for a medical device. This is an example of:

• Early testing

• Context-dependent testing

• Defect clustering

• Exhaustive testing

A company only involves testers at the end of the development cycle, leading to costly fixes. What principle was violated?

• Pesticide paradox

• Exhaustive testing

• Early testing

• Absence-of-errors fallacy

The belief that fixing all defects will result in a perfect system is incorrect. This relates to which principle?

• Testing shows the presence of defects

• Absence-of-errors fallacy

• Pesticide paradox

• Defect clustering

What is the main reason exhaustive testing is impossible?

• Limited budget

• Too many input combinations

• Poor software quality

• Testers are inexperienced

Risk analysis should be used to prioritize test cases because:

• Not all features are equally important

• Every function must be tested equally

• Testing eliminates all risks

• Testing proves software is perfect
