One of my most-hated methods in Pharo

    TestCase>fail
         ^self assert: false

What's wrong? Well, I often write self fail at the end of a unit test to remind myself that the test isn't yet done. Now, if I run the test, I care whether an assertion failed or whether the test solely failed. Of course I have no right to expect should detailed feedback from a test runner. But at least I shouldn't be misinformed. But that's exactly what happens. The TestRunner reports that an assertion failed if you call fail, even if none did.
