Customization - Do you use the built-in test form events before you publish JavaScript changes?

Generally you will add Javascript to the form to give client side validation. Given JavaScript is difficult to debug and doesn't get precompiled this can save a lot of time rather than re-publishing all the form changes and having to reload and refresh the forms manually. These events can be trigged using the Preview menu from the form customization environment.

Figure: Test your Javascript via the Preview menu in the Custom Forms Designer
