Questions Related to testing

We split testing into distinct stages primarily because:
technology testing

  1. Each test stage has a different purpose

  2. It is easier to manage testing in stages

  3. We can run different tests in different environments

  4. The more stages we have, the better the testing

Show answer
Correct Option: A

  2. Regression testing

  3. System testing

  4. User acceptance testing

Show answer
Correct Option: B

Which of the following requirements is testable?

technology testing

  1. The system shall be user friendly.

  2. The safety-critical parts of the system shall contain 0 faults.

  3. The response time shall be less than one second for the specified design load.

  4. The system shall be built to be portable.

Show answer
Correct Option: C

AI Explanation

To answer this question, we need to understand what makes a requirement testable. A testable requirement is one that can be objectively verified or validated. Let's go through each option to understand why it is correct or incorrect:

Option A) The system shall be user friendly - This option is not testable. "User-friendly" is a subjective term and can mean different things to different people. It is difficult to objectively verify or validate if a system is user-friendly.

Option B) The safety-critical parts of the system shall contain 0 faults - This option is not testable. While it is desirable for safety-critical parts to have zero faults, it is impossible to prove that there are absolutely no faults in a system. Testing can help identify and mitigate faults, but it cannot guarantee zero faults.

Option C) The response time shall be less than one second for the specified design load - This option is testable. The requirement specifies a measurable and objective criterion (response time less than one second) that can be validated through testing. The system can be tested to see if it meets this requirement.

Option D) The system shall be built to be portable - This option is not testable. "Portable" is a vague term and can have different interpretations. It is difficult to objectively verify or validate if a system is built to be portable.

The correct answer is C) The response time shall be less than one second for the specified design load. This option is testable because it specifies a measurable and objective criterion that can be validated through testing.

In prioritizing what to test, the most important objective is to

technology testing

  1. find as many faults as possible.

  2. obtain good test coverage

  3. test whatever is easiest to test.

  4. test high risk areas

Show answer
Correct Option: D

Which one of the following statements about system testing is NOT true?
technology testing

  1. System tests are often performed by independent teams.

  2. Functional testing is used more than structural testing.

  3. Faults found during system tests can be very expensive to fix

  4. End-users should be involved in system tests.

Show answer
Correct Option: D

Enough testing has been performed when
technology testing

  1. time runs out.

  2. the required level of confidence has been achieved.

  3. no more faults are found.

  4. the users won’t find any serious faults.

Show answer
Correct Option: B
