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.

Installation edit

Expect depends on modules from the Scribunto extension.

  • Download and place the file(s) in a directory called Expect in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'Expect' );
    
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Usage edit

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 )
end

-- Return the exported hash
return p
