4 Running the test-suite

At any time, the tests can be executed by loading the program and running run_tests/0 or run_tests(+Unit).

run_tests

Run all test-units.

run_tests(+Spec)

Run only the specified tests. Spec can be a list to run multiple tests. A single specification is either the name of a test unit or a term <Unit>:<Tests>, running only the specified test. <Tests> is either the name of a test or a list of names. Running particular tests is particularly useful for tracing a test:^{6Unfortunately the body of the test is called through meta-calling, so it cannot be traced. The called user-code can be traced normally though.}

?- gtrace, run_tests(lists:member).

To identify nonterminating tests, interrupt the looping process with Control-C. The test name and location will be displayed.
