Q

What is unit testing? (Junit)

A

Focuses on individual components (class or subsystem)

Goal: confirm that the component or subsystem is correctly coded and carries out the intended functionality

Techniques:
Black-box and white box testing

Q

What is black-box testing?

A

Focus on I/O behaviour

If for any given input, we can predict the output, then the unit passes the test.

Goal: reduce number if test cases by equivalence partitioning.

Q

What is white-box testing?

A

Focus: thoroughness (coverage)
Every statement in the component is executed at least once.

E.g. Path testing (A flow graph extracted from a program (if and while conditions)

17
Q

What is integration testing?

A

Groups of subsystems and eventually the entire system are tested.

Goal: test the interfaces among the subsystems

18
Q

What is system testing?

A

The entire system is tested.

Goal: determine if the system meets the requirements (functional and nonfunctional)

   - >Functional testing (requirements testing)
   - >Performance testing: tests of nonfunctional requirements
19
Q

What is acceptance testing?

A

Evaluates the system delivered by developers.

Goal: Demonstrates that the system meets the requirement and is easy to use.

(Think about how the mini project was evaluated)
