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 conditional statements
which have been taken.
The most basic level of test coverage is code coverage testing 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.
