+`autotest` module
+=================
+
+This module provides an interface to do automatic testing of authentication sources.
+To enable it, create a file named "enable" in modules/autotest.
+
+It provides three webpages:
+- https://.../simplesaml/module.php/autotest/login.php
+- https://.../simplesaml/module.php/autotest/logout.php
+- https://.../simplesaml/module.php/autotest/attributes.php
+
+All the webpages have a mandatory paremeter 'SourceID', which is the name of the authentication source.
+
+On success, the web pages print a single line with "OK".
+The attributes page will also list all the attributes of the user.
+On error they set the HTTP status code to 500 Internal Server Error, print a line with "ERROR" and then any information about the error.
+
+Note that you still have to parse the login pages to extract the parameters in the login form.
