Module:UnitTests/doc explained

UnitTests provides a unit test facility that can be used by other scripts using require. See for details. The following is a sample from :

The talk page executes it with <nowiki>{{#invoke: Example/testcases | run_tests}}</nowiki>. Test methods like test_hello above must begin with "test".

Methods

run_tests

• : Runs all tests. Normally used on talk page of unit tests.

• If is specified, a column will be added showing the first character position where the expected and actual results differ.

• If is specified, failed tests will be highlighted to make them easier to spot. A user script that moves failed tests to the top is also available.

• If is specified, the header will show the columns "Test", "Live", "Sandbox", "Expected". This is required when using the method.

preprocess_equals

• : Gives a piece of wikitext to preprocess and an expected resulting value. Scripts and templates can be invoked in the same manner they would be in a page.

self:preprocess_equals('', 'Hello, world!',)

preprocess_equals_many

• : Performs a series of preprocess_equals calls on a set of given pairs. Automatically adds the given prefix and suffix to each text.

self:preprocess_equals_many('',,)

preprocess_equals_preprocess

• : Gives two pieces of wikitext to preprocess and determines if they produce the same value. Useful for comparing scripts to existing templates.

self:preprocess_equals_preprocess('', '',)

preprocess_equals_preprocess_many

• : Performs a series of preprocess_equals_preprocess calls on a set of given pairs. The prefix/suffix supplied for both arguments is added automatically. If in any case the second part is not specified, the first part will be used.

self:preprocess_equals_preprocess_many('', '',,)

preprocess_equals_sandbox_many

• : Performs a series of preprocess_equals_compare calls on a set of given pairs. The test compares the live version of the module vs the /sandbox version and vs an expected result. Ensure live_sandbox is specified or there may be some errors in the output.
