This file contains multiple primitive tests for avoiding performance regressions.
|
|
|
|
- Time bound tests: Benchmarks are done on GHA before adding numbers
|
|
- Query count tests: More than expected # of queries for any action is frequent source of
|
|
performance issues. This guards against such problems.
|
|
|
|
|
|
E.g. We know get_controller is supposed to be cached and hence shouldn't make query post first
|
|
query. This test can be written like this.
|
|
|
|
>>> def test_controller_caching(self):
|
|
>>>
|
|
>>> get_controller("User") # <- "warm up code"
|
|
>>> with self.assertQueryCount(0):
|
|
>>> get_controller("User")
