HttpUnit and jQuery: EcmaError

Question

Currently I'm developing unit tests for j2ee application. It uses jQuery version 1.4.

And when I'm trying to click the link and go the next web page(in java test code), HttpUnit fails with exception:

Does anybody knows any workaround to avoid this error ? Thanks !

Answer 1

The only way I've found is to refuse using HttpUnit and choose between jWebUnit and HtmlUnit

Answer 2

As a workaround I would recomment disabling Javascript:

HttpUnitOptions.setScriptingEnabled(false);
