Yes. From the docs [1]: """ This flush/load procedure is repeated for each test in the test case, so you can be certain that the outcome of a test will not be affected by another test, or by the order of test execution. """ [1] http://docs.djangoproject.com/en/dev/topics/testing/#fixture-loading > If so, how would I create a series of test methods that build on each > other: for example, one view test creates an object that then will be > retrieved by the next view test? You wouldn't. :-) Each test in a unittest TestCase is supposed to stand alone. You should be able to run any single test from the suite, or any subset of tests, in any order, and get the same passes or failures. Tests *shouldn't* be order dependent. It sounds like what you actually want to write is one long test, rather than N order dependent short tests. If you want to break things into methods for the sake of clarity/code organization, you can - just break the test_* entry method into smaller parts: class MyTest(TestCase): def test_long_test(self): self._part1() self._part2() ... self._partN() def _part1(self): .... Better still, write separate test cases, with separate test fixtures. 1) CreateTestCase, starting with an empty database, checking that you can create new objects 2) EditTestCase, starting with a populated database, checking that you can edit an existing object. Each edit operation starts with the same starting point. Yours, Russ Magee %-) -- You received this message because you are subscribed to the Google Groups "Django users" group.
