Oscar uses pytest to run the tests, which can be invoked using:
You can run a subset of the tests by passing a path:
$ ./runtests.py tests/unit/offer/availability_tests.py
To run an individual test class, use:
$ ./runtests.py tests/unit/offer/availability_tests.py::TestASuspendedOffer
(Note the ‘::’.)
To run an individual test, use:
$ ./runtests.py tests/unit/offer/availability_tests.py::TestASuspendedOffer::test_is_unavailable
You can also run tests which match an expression via:
$ ./runtests.py tests/unit/offer/availability_tests.py -k is_unavailable
Testing against different setups¶
To run all tests against multiple versions of Django and Python, use detox:
You need to have all Python interpreters to test against installed on your system. All other requirements are downloaded automatically. detox is a wrapper around tox, creating the environments and running the tests in parallel. This greatly speeds up the process.
Kinds of tests¶
Tests are split into 3 folders:
- unit - These are for tests that exercise a single unit of functionality, like a single model. Ideally, these should not write to the database at all - all operations should be in memory.
- integration - These are for tests that exercise a collection or chain of units, like testing a template tag.
- functional - These should be as close to “end-to-end” as possible. Most of these tests should use WebTest to simulate the behaviour of a user browsing the site.
When running a subset of tests, Oscar uses the spec plugin. It is a good practice to name your test cases and methods so that the spec output reads well. For example:
$ py.test tests/integration/catalogue/product_tests.py --spec ============================== test session starts ============================== platform darwin -- Python 2.7.9 -- py-1.4.26 -- pytest-2.7.0 rootdir: /Users/mvantellingen/projects/django-oscar, inifile: setup.cfg plugins: cache, cov, django, spec, xdist collected 15 items tests/integration/catalogue/product_tests.py::ProductCreationTests [PASS] Allow two products without upc [PASS] Create products with attributes [PASS] None upc is represented as empty string [PASS] Upc uniqueness enforced tests/integration/catalogue/product_tests.py::TopLevelProductTests [PASS] Top level products are part of browsable set [PASS] Top level products must have product class [PASS] Top level products must have titles tests/integration/catalogue/product_tests.py::ChildProductTests [PASS] Child products are not part of browsable set [PASS] Child products dont need a product class [PASS] Child products dont need titles [PASS] Child products inherit fields [PASS] Have a minimum price tests/integration/catalogue/product_tests.py::TestAChildProduct [PASS] Delegates requires shipping logic tests/integration/catalogue/product_tests.py::ProductAttributeCreationTests [PASS] Entity attributes [PASS] Validating option attribute =========================== 15 passed in 1.64 seconds ===========================
