Avoid questionable use of ClassPathResource#getPath() in tests

Browse Source 
Prior to this commit, several tests used ClassPathResource#getPath()
based on the knowledge that the ClassPathResource had been created
using the ClassPathResource(String,Class) constructor. However, making
such an assumption seems ill advised in light of the abstraction that
ClassPathResource provides.

In light of that, this commit avoids questionable use of
ClassPathResource#getPath() in tests by refactoring those tests to use
the proper abstractions provided by ClassPathResource.
