There are six types of testing which are as follows:

Unit Testing

Specification: Low-level design and/or code structure

Integration testing
Opacity: Black- and white-box testing

Functional and system testing
Opacity: Black-box testing
Specification: high-level design, requirements specification

Acceptance testing
Opacity: Black-box testing
Specification: requirements specification

Regression testing
