Meh. Pedant time.

The first step of every testcase is supposed to fail to ensure a testing framework can fail in the scope of the testcase. In practice nobody acknowledges this, much less incorporates it.

Without, one is forced to concede that the test environment is not sane—and, therefore, no case under test is certifiable—because it cannot be known, for certain, if failure was a possibility.

Nobody cares.
