What you want is a TAssertable>>#should:raise: that:
- takes a one arg block as second argument that is evaluated with the
exception thrown
- fails if no exception is raised
Then please call it #should:raise:suchThat:
That's what is in upcoming SUnit 5.0 [1]
Also I would avoid using traits in SUnit, this is
non-portable. The TestAsserter class was introduced already
in SUnit 4.0. Indeed, only if you at all care about having SUnit in sync
with other dialects :-)
Best, Jan
