Chapter 7: Software testing

Which of the following best describes the principle “Testing shows the presence of defects”?

• Testing guarantees the software is 100% bug-free

• Testing helps identify existing defects but does not prove their absence

• Testing ensures the software meets deadlines

• Testing prevents all bugs from appearing after deployment

What is the main reason exhaustive testing is not possible?

• It is illegal in most countries

• It takes too much time and resources to test all possible combinations

• Users prefer fewer tests

• It guarantees too many bugs are found

According to the principle of Early Testing, why should tests begin during the requirements stage?

• It makes developers work faster

• Finding defects early is cheaper and easier to fix

• It ensures the software will be bug-free

• It avoids the need for test planning

Defect Clustering follows which principle?

• 100% testing principle

• Pareto Principle (80% of defects come from 20% of modules)

• Black Box Principle

• Regression Principle

In the Pesticide Paradox, running the same tests repeatedly will:

• Find more bugs

• Make the software slower

• Guarantee defect-free software

• Stop finding new bugs over time

Which phase of the Software Testing Life Cycle involves preparing the list of all requirements and test environment details?

• Requirement Analysis

• Test Plan Creation

• Test Cycle Closure

• Environment Setup

Which type of software testing technique involves checking the software without executing the code?

• Static Testing

• Dynamic Testing

• Regression Testing

• Acceptance Testing

What is the main purpose of Regression Testing?

• To test software performance under load

• To test the software’s security

• To check if recent changes have introduced new defects

• To evaluate user-friendliness

White Box Testing is also known as:

• Closed Box Testing

• Transparent Box Testing

• Black Box Testing

• Functional Testing

Which of these is an example of a Black Box Testing technique?

• Equivalence Class Partitioning (ECP)

• Loop Testing

• Control Flow Testing

• Branch Testing
