Question

Tryng out some smalltalk + TDD + ‘good practices’ I’ve run into a kinda ugly block:

How do I do an assertion in GNU Smalltalk?

I’m just looking for a simple ifFalse: [Die] kind of thing

Answer 1

This is the code for assert: from Squeak (which I recommend you use rather than GNU):

assert: aBlock      'Throw an assertion error if aBlock does not evaluates to true.'     aBlock value         ifFalse: [AssertionFailure signal: 'Assertion failed']
