  2. To test the integration of multiple units of code

  3. To test the performance of a software system

  4. To test the security of a software system
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The purpose of a unit test is to test the functionality of a single unit of code.

Multiple choice

What is the Turing Test?

  1. A test to determine if a machine can exhibit intelligent behavior indistinguishable from that of a human.

  2. A test to determine if a machine can pass a college-level exam.

  3. A test to determine if a machine can play chess at a grandmaster level.

  4. A test to determine if a machine can write poetry.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Turing Test is a test of a machine's ability to exhibit intelligent behavior indistinguishable from that of a human. The test is based on the idea that if a machine can fool a human into thinking that it is human, then it can be said to be intelligent.

Multiple choice

What is the comparison test for convergence?

  1. If the sequence is bounded above by a convergent sequence, then the sequence is convergent.

  2. If the sequence is bounded below by a divergent sequence, then the sequence is divergent.

  3. Both of the above

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The comparison test for convergence states that if the sequence is bounded above by a convergent sequence, then the sequence is convergent, and if the sequence is bounded below by a divergent sequence, then the sequence is divergent.

Multiple choice

Which of the following is NOT a type of quality control inspection method?

  1. Visual inspection

  2. Dimensional inspection

  3. Non-destructive testing

  4. Customer feedback
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Customer feedback is a form of quality assurance, not a quality control inspection method. Quality control inspection methods are used to verify that products meet specified requirements.

Multiple choice

Which testing technique involves dividing the system into smaller, manageable components for individual testing?

  1. Unit Testing

  2. Integration Testing

  3. System Testing

  4. Acceptance Testing
