question: public void testExampleKeystorePath ( ) { assertNotNull ( "Example keystore is null, meaning that something has changed in the " + "structure of the example configs and/or ExternalPaths.java - " + "SSL randomization is broken" , SSLTestConfig . TEST_KEYSTORE ) ; }
target:  A trivial test that verifies the example keystore used for SSL testing can be  found using the base class. this helps future-proof against the possibility of  something moving/breaking the keystore path in a way that results in the SSL  randomization logic being forced to silently never use SSL.  (We can't enforce  this type of check in the base class because then it would not be usable by client  code depending on the test framework
