Module:UnitTests (talk<dot-separator>edit<dot-separator>hist<dot-separator>links<dot-separator>doc<dot-separator>subpages<dot-separator>tests / results<dot-separator>sandbox<dot-separator>all modules)
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/testcases:
-- 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/testcases executes it with {{#invoke: Bananas/testcases | run_tests}}. Test methods like test_hello above must begin with "test".
Methods
run_tests
-
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/testcases|run_tests}}
preprocess_equals
-
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
-
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
-
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
-
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_preprocess_many('{{#invoke:Foo | spellnum |', '}}', '{{spellnum', '}}', {
{'2'}, -- equivalent to {'2','2'},
{'-2', '-2.0'},
})
equals
-
equals(name, actual, expected): 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)
equals_deep
-
equals_deep(name, actual, expected): 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})
