Compiles the test class with bogus code into a .class file. Unfortunately it's very tedious.

Parameters:

counter - Unique test counter.

packageNameSuffix - Package name suffix (e.g. ".suffix") for nesting, or "".

Returns:

The resulting .class file and the location in jar it is supposed to go to.

Throws:

Exception

Makes a jar out of some class files. Unfortunately it's very tedious.

Parameters:

filesInJar - Files created via compileTestClass.

Returns:

path to the resulting jar file.

Throws:

Exception
