Test coverage

testing A measure of the proportion of a program exercised

by a test suite, usually expressed as a percentage. This

will typically involve collecting information about which

parts of a program are actually executed when running the test

suite in order to identify which branches of conditionalstatements which have been taken.

The most basic level of test coverage is code coveragetesting and the most methodical is path coverage testing.

Some intermediate levels of test coverage exist, but are

rarely used.

The standard Unix tool for measuring test coverage is

tcov, which annotates C or Fortran source with the

results of a test coverage analysis. GCT is a GNU

equivalent.
