plunit.pl -- Unit Testing

Unit testing environment for SWI-Prolog and SICStus Prolog. For usage, please visit http://www.swi-prolog.org/pldoc/package/plunit.

set_test_options(+Options)

Specifies how to deal with test suites. Defined options are:

load(+Load): Whether or not the tests must be loaded. Values are never, always, normal (only if not optimised)
run(+When): When the tests are run. Values are manual, make or make(all).
silent(+Bool): If true (default false), report successful tests using message level silent, only printing errors and warnings.
sto(+Bool): How to test whether code is subject to occurs check (STO). If false (default), STO is not considered. If true and supported by the hosting Prolog, code is run in all supported unification mode and reported if the results are inconsistent.
cleanup(+Bool): If true (default =false), cleanup report at the end of run_tests/1. Used to improve cooperation with memory debuggers such as dmalloc.
concurrent(+Bool): If true (default =false), run all tests in a block concurrently.

begin_tests(+UnitName:atom) is det

begin_tests(+UnitName:atom, Options) is det

Start a test-unit. UnitName is the name of the test set. the unit is ended by :- end_tests(UnitName).

end_tests(+Name) is det

Close a unit-test module.

To be done: - Run tests/clean module?; - End of file?

run_tests is semidet

run_tests(+TestSet) is semidet

Run tests and report about the results. The predicate run_tests/0 runs all known tests that are not blocked. The predicate run_tests/1 takes a specification of tests to run. This is either a single specification or a list of specifications. Each single specification is either the name of a test-unit or a term <test-unit>:<test>, denoting a single test within a unit.

running_tests is det

Print the currently running test.

current_test(?Unit, ?Test, ?Line, ?Body, ?Options)

True when a test with the specified properties is loaded.

test_report(What) is det

Produce reports on test results after the run.

load_test_files(+Options) is det

Load .plt test-files related to loaded source-files.

user:message_hook(+Severity, +Message, +Lines) is semidet[multifile]

Redefine printing some messages. It appears SICStus has no way to get multiple messages at the same line, so we roll our own. As there is a lot pre-wired and checked in the SICStus message handling we cannot reuse the lines. Unless I miss something ...
