Tests do not run in a predefined order, so you cannot make assumptions on that.
What you can do, is to let your TestResource return different
resources based on the context, i.e. the test class that requests it.
MyTestCase>>singleton
^ MyTestResource current singletonFor: self
MyTestResource>>singletonFor: aTestCase
^ singletonCache at: aTestCase class ifAbsentPut: [ aTestCase
buildSingleton ]
If you want to see an example of this pattern have a look at the tests
of PetitParser. PPCompositeParserTest (and its subclasses) and
PPParserResource do exactly follow that pattern.
