UnitTests provides a unit test facility that can be used by other scripts using require. See Wikipedia:Lua#Unit_testing for details. Following is a sample from Module:Bananas/tests:

-- Unit tests for [[Module:Bananas]]. Click talk page to run tests. local p = require('Module:UnitTests') function p:test_hello() self:preprocess_equals('{{#invoke:Bananas | hello}}', 'Hello, world!') end return p 

The talk page Module talk:Bananas/tests executes it with {{#invoke: Bananas/tests | run_tests}}. Test methods like test_hello above must begin with "test".

Methods

• run_tests(differs_at): Runs all tests. If "differs_at=1" is specified, a column will be added showing the first character position where the expected and actual results differ. Normally used on talk page of unit tests.

 {{#invoke:Bananas/tests|run_tests}} 

• preprocess_equals(text, expected): 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('{{#invoke:Bananas | hello}}', 'Hello, world!') 

• preprocess_equals_many(prefix, suffix, cases): 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('{{#invoke:BananasArgs | add |', '}}', { {'2|3', '5'}, {'-2|2', '0'}, }) 

• preprocess_equals_preprocess(text, expected): 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('{{#invoke:Bananas | hello}}', '{{Hello}}') 

• preprocess_equals_preprocess_many(prefix, suffix, cases): 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_many('{{#invoke:Foo | spellnum |', '}}', '{{spellnum', '}}', { {'2'}, -- equivalent to {'2','2'}, {'-2', '-2.0'}, }) 

• equals(name, actual, expected): Gives a computed value and the expected value, and checks if they are equal. Useful for testing modules that are designed to be used by other modules rather than using #invoke.
