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

作为一种解决方法，我建议禁用Javascript：

HttpUnitOptions.setScriptingEnabled(false);

Answer 2

我发现的唯一方法是拒绝使用HttpUnit并在jWebUnit和HtmlUnit之间进行选择
