Testing your Windows with the MP! Interface Tester

Complex windows created with XML data can quickly become difficult to visualize and testing your windows in Messenger itself can sometimes cause additional complications and unnecessary delays. For those reasons, a special tool called "Interface Tester" is provided with the scripting API to help developers preview their creations quickly and without hassle.

"Interface Tester" will be able to preview any file that is located in a sub-directory of the Messenger Plus!'s "Scripts" directory or in the "Interface" directory (for those interested in skinning Messenger Plus! itself).

In addition to displaying your windows on screen, "Interface Tester" is also capable of validating your XML files if the schema file is copied in the same directory and if MSXML 5.0 or above is installed on your system (you can get MSXML at It is highly recommended that you do not redistribute any file that does not validate against the most current version of the Interface Windows' Schema File.
