Display the Aperçu window by clicking on a test and choosing the
Fichier > Aperçu
menu command, or the [Aperçu] 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.
