Coverage Criteria

Test Requirement
- A test requirement is a specific element of a software artifact that a test case must satisfy or cover.
Coverage Criterion
- A coverage criterion is a rule or collection of rules that impose test requirements on a test set.
Coverage
- Given a set of test requirements TR for a coverage criterion C,
  - a test set T satisfies C if and only if for every test requirement tr in TR, at least one test t in T exists such that t satisfies tr.
Coverage Level
- Given a set of test requirements TR and a test set T,
  - the coverage level is simply the ratio of the number of test requirements satisfied by T to the size of TR.
