Refactor EppToolVerifier to accept chaining verify commands
We're doing this to allow several new tests:
- xml files (that exist today)
- xml files with substitutions
- xml content (maybe? Currently private. Caching the files seems more readable)
- no data at all
Instead of having only one interface
eppToolVerifier.verifySent("file1.xml", "file2.xml");
we're refactoring to allow:
eppToolVerifier
.verifySent("file1.xml")
.verifySentAny() // we don't care about this epps
.verifySent("file2.xml", substitutions)
.verifyNoMoreSent();
In this case we're checking that "exactly 3 EPPs were sent, where the 1st one has content from file1.xml, and the 3rd one has the content from file2.xml, after the given substitutions were applied"
This also updates EppToolCommandTestCase to have only one EppToolVerifier, and
always finish by checking verifyNoMoreSent, meaning that in every test - all
sent epps must be accounted for (verified or skiped)
