When an org.junit.Assert.assertEquals fails in a test I'm running under Pax
Exam, I get an unhelpful stack trace in the HTML test results. The testcase is
not present in the stack trace, so it's hard to see which assert failed. (I
can't see the 'right' stack trace anywhere else, e.g. in logs, for that
matter.) The full stack trace is immediately below.
I tried running under Eclipse and putting a breakpoint at
JUnit4TestRunner.java:263, but the caught exception was even more cryptic. See
further below (and apologies for the lack of formatting).
When I comment out the assertEquals in the testcase, the test passes both under
Gradle and under Eclipse, so I have the feeling that the test configuration is
reasonable.
Any suggestions?
Regards,
Glyn
