test coverage

A measure of how thoroughly a test suite exercises a program.

This will typically involve collecting information about which

parts of a program are actually executed when running the test

suite in order to identify branches of conditional statements

which have not been taken etc. The standard {Unix} tool for

this is {tcov} which annotates {C} or {Fortran} source with

the results of a test coverage analysis. {GCT} is a {GNU}

equivalent.
