There are quite a lot of assertions that don't give any details if a test fails.
For example, the following currently fails when using Harmony: testIncreasingTolerance(org.apache.commons.math.ode.nonstiff.AdamsBashforthIntegratorTest) java.lang.AssertionError: at org.junit.Assert.fail(Assert.java:74) at org.junit.Assert.assertTrue(Assert.java:37) at org.junit.Assert.assertTrue(Assert.java:46) at org.apache.commons.math.ode.nonstiff.AdamsBashforthIntegratorTest.testIncreasingTolerance(AdamsBashforthIntegratorTest.java:89) Obviously one can find the code from the line number, but that does not actually get one much further as there's no indication what the values are: assertTrue(handler.getMaximalValueError() < (36.0 * scalAbsoluteTolerance)); Seems to me it might be useful to create some additional assert methods, for example: assertLessThan([message,] maximum, actual) which would report the max and actual values if the check failed. As far as I can tell, this is not currently supported by JUnit3/4 - only assertSame/assertEquals report the expected and actual values. WDYT? There are also lots of cases of assert() calls without a message; again this means digging into the test code to find the problem. I propose to add messages to at least the ones that Harmony triggers.
