# Preview window for others

Display the Preview window by clicking on a test and choosing the FilePreview menu command, or the Preview toolbar button. This describes the Preview window for services like the Script service. The Web (HTML) service uses a web browser-like variation.

This window shows the source (e.g. of the script) in the top half, and the output of that script in the bottom half, separated by a splitter bar that allows you to change the proportion of each that is displayed. At the bottom of the window is a display of the result of the check: success or an error message.
