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

-- Unit tests for [[Module:Example]]. Click talk page to run tests.
local p = require('Module:UnitTests')

function p:test_hello()
    self:preprocess_equals('Hello World!', 'Hello World!')
end

return p

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

Methods[çavkaniyê biguhêre]

run_tests[çavkaniyê biguhêre]

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

    {{#invoke:Example/testcases|run_tests}}

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

    {{#invoke:Example/testcases|run_tests|differs_at=1}}

If highlight 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.

    {{#invoke:Example/testcases|run_tests|highlight=1}}

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

preprocess_equals[çavkaniyê biguhêre]

preprocess_equals(text, expected, options): 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:Example | hello}}', 'Hello, world!', {nowiki=1})

preprocess_equals_many[çavkaniyê biguhêre]

preprocess_equals_many(prefix, suffix, cases, options): 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:Example | hello_to |', '}}', {
        {'John', 'Hello, John!'},
        {'Jane', 'Hello, Jane!'},
    }, {nowiki=1})

preprocess_equals_preprocess[çavkaniyê biguhêre]

preprocess_equals_preprocess(text, expected, options): 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:Example | hello}}', '{{Hello}}', {nowiki=1})

preprocess_equals_preprocess_many[çavkaniyê biguhêre]

preprocess_equals_preprocess_many(prefix1, suffix1, prefix2, suffix2, cases, options): 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('{{#invoke:ConvertNumeric | numeral_to_english|', '}}', '{{spellnum', '}}', {
        {'2'}, -- equivalent to {'2','2'},
        {'-2', '-2.0'},
    }, {nowiki=1})

preprocess_equals_sandbox_many[çavkaniyê biguhêre]

preprocess_equals_sandbox_many(module, function, cases, options): 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.

    self:preprocess_equals_sandbox_many('{{#invoke:Example', 'hello_to', {
        {'John', 'Hello, John!'},
        {'Jane', 'Hello, Jane!'},
    }, {nowiki=1})

equals[çavkaniyê biguhêre]

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

    self:equals('Simple addition', 2 + 2, 4, {nowiki=1})

equals_deep[çavkaniyê biguhêre]

equals_deep(name, actual, expected, options): Like equals, but handles tables by doing a deep comparison. Neither value should contain circular references, as they are not handled by the current implementation and may result in an infinite loop.

    self:equals_deep('Table comparison', createRange(1,3), {1,2,3}, {nowiki=1})

Test options[çavkaniyê biguhêre]

These are the valid options that can be passed into the options parameters of the test functions listed above.

nowiki[çavkaniyê biguhêre]

Enabling this wraps the output text in <nowiki>...</nowiki> tags to avoid the text being rendered (E.g. <span>[[Example|Page]]</span> instead of Page)

combined[çavkaniyê biguhêre]

Enabling this will display the output text in both the rendered mode and the nowiki mode to allow for both a raw text and visual comparison.

templatestyles[çavkaniyê biguhêre]

Enabling this fixes the IDs in the strip markers <templatestyles>...</templatestyles> produces when processed to avoid incorrectly failing the tests.

stripmarker[çavkaniyê biguhêre]

Enabling this fixes the IDs in all strip markers produces when processed to avoid incorrectly failing the tests.

display[çavkaniyê biguhêre]

An optional function that changes how the output from the tests are displayed. This doesn't effect the comparison process.
