To run tests from the Prolog prompt, first load the program and then
run 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:5Unfortunately
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.
To run a file's tests from the command line, run the following
command, replacing your/file.pl with the path to your file.
swipl -g run_tests -t halt your/file.pl
Prolog will (1) load the file you specify, as well as any modules it
depends on; (2) run all tests in those files, and (3) exit with status 0
or 1 depending on whether the test suite succeeds or fails.
If you want to test multiple files, you can pass multiple ..pl
files.
