Modul:UnitTests/doc

UjianUnit (UnitTests) menyediakan kemudahan menguji unit yang dapat digunakan oleh skrip lain dengan mengguna require. Lihat Wikipedia:Lua#Ujian_unit bagi mendapatkan perincian. Berikut ini adalah sampel daripada Modul:Pisang/kes_ujian

-- Ujian unit untuk [[Modul:Pisang]]. Petik tab laman perbincangan untuk melaksanakan ujian.

local p = require('Modul:UnitTests')
 
function p:test_hello()
    self:preprocess_equals('{{#invoke:Pisang | helo}}', 'Helo, dunia!')
end
 
return p

Laman perbincangan di Module_talk:Pisang/kes_ujian (perhatikan ejaan ruang nama "Module_talk") melaksanakannya dengan {{#invoke: Pisang/kes_ujian | run_tests}}. Kaedah-kaedah ujian seperti test_hello perlu bermula dengan "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})
