Hi Martin,
I have not tried any code (also not from Dexterity), only read your
article. Some things are not clear to me.
- At the end of the first mock example you say: "We must remember to put
the test case into replay mode, using self.replay()." Why? What does
that do?
- In the third mock example you say that we "set the expectation that
lookup_schema() should be called on it once", stressing the word
'once'. Which part of the test code does that? From the paragraphs
after that I *guess* that whenever the code is this:
self.expect(...).result(...)
it implicitly means this:
self.expect(...).result(...).count(1, 1)
Is that a correct guess? If so, I think you should mention that
explicitly, perhaps already in the first mock example.
BTW, if that is correct then I would find "count(0, None)" a more
logical default, so by default no restriction on the number of times
a mocked method is called.
And a question: is there next to mock_utility also something like
mock_tool, so you could you this to mock for example the
portal_catalog? I guess something along these lines might work:
from whereever import CatalogTool
catalog_mock = self.mocker.proxy(CatalogTool())
context_mock = self.mocker.mock()
self.expect(context_mock.portal_catalog).result(catalog_mock).count(0,None)
