Translate the Expect extension

Expect provides an extended framework for assertions.

It is based upon compute graphs that are predefined before being used for extensive checks.


Expect depends on modules from the Scribunto extension.

  • Die Erweiterung herunterladen und die Datei(en) in ein Verzeichnis namens Expect im Ordner extensions/ ablegen.
  • Folgenden Code am Ende Ihrer LocalSettings.php -Datei hinzufügen:
    wfLoadExtension( 'Expect' );
  •   Done – Zu Special:Version in dem Wiki (bei Einstellung auf deutsch nach Spezial:Version) navigieren, um die erfolgreiche Installierung der Erweiterung zu überprüfen.


The workflow is to define a graph, and then provide arguments to that graph. The definition is done once, but the graph can be reused several times.

-- Load the lib
local expect = require 'expect'

-- Create a few compute graphs
local expectString = expect:create():asType():toBeEqual( 'string' )
local expectNoColon = expect:create():toBeUMatch( '^[^:]*$' )

-- Create an exported hash
local p = {}

-- Add a function
function p.helloWorld( name )
	-- Call the compute graphs
	expectString( name )
	expectNoColon( name )

	-- Should be safe to do whatever now
	return mw.ustring.format( 'Hi there %s!', name )

-- Return the exported hash
return p
