Can JStestDriver be used to test js code within JSP files?

Question

Quick question:

It is possible to do unit testing, particularly with JStestDriver, on Javascript code written inside JSP files?

Or I have to necessarily extract it into external js files?

Answer 1

The JavaScript source with the substitutions from the compiled JSP have to be extracted into separate files. Here is an example using CoffeeScript:

• CoffeeScript TDD

For JSP in particular, it is necessary to find the path to the compiled output and debug the result. Use jspc, the JSP compiler, to test the output with JsTestDriver.

The jspc command-line tool enables you to precompile JSPs at the command line.

You must disable dynamic reloading of JSP when deploying a web application archive that has precompiled JSP without the corresponding jsp source files.
