Testing Questions (ISTQB related)

Which of the following statements is a valid objective for testing?

• To determine whether enough component tests were executed within system testing.

• To find as many failures as possible so that defects can be identified and corrected.

• To prove that all possible defects are identified.

• To prove that any remaining defects will not cause any failures.

Which of the following statements correctly describes the difference between testing and debugging?

• Testing shows failures caused by defects; debugging finds, analyzes, and removes the causes of failures in the software.

• Testing identifies the source of defects; debugging analyzes the defects and proposes prevention activities.

• Testing removes faults; debugging identifies the causes of failures.

• Testing prevents the causes of failures; debugging removes the failures.

A program with high cyclometic complexity is almost likely to be:

• Large

• Difficult to test

• Difficult to write

• Small

Enough testing has been performed when:

• time runs out

• no more faults are found

• the required level of confidence has been achieved

• the users won’t find any serious faults

Software testing activities should start

• as soon as the code is written

• during the design stage

• when the requirements have been formally documented

• as soon as possible in the development life cycle

What is the main reason for testing software before releasing it?

• to give information for a risk based decision about release

• to decide when the software is of sufficient quality to release

• to find as many bugs as possible before release

• to show that system will work after release

Increasing the quality of the software, by better development methods, will affect the time needed for testing (the test phases) by:

• no change

• reducing test time

• increasing test time

• can’t say

What is the important criterion in deciding what testing technique to use?

• how well you know a particular technique

• how appropriate the technique is for testing the application

• the objective of the test

• whether there is a tool to support the technique

Which of the following statements are true?

• Faults in program specifications are the most expensive to fix.

• Faults in code are the most expensive to fix.

• Faults in designs are the most expensive to fix.

• Faults in requirements are the most expensive to fix.

Faults found by users are due to:

• Poor software and poor testing

• Poor quality software

• bad luck

• insufficient time for testing
