django 测试没有为测试创建数据库

Question

i am trying to run tests with python manage.py test the output is this. the directory that contains my test file has an init file. i have two test files also, i'm not sure if that would affect it.

System check identified no issues (0 silenced).

----------------------------------------------------------------------
Ran 0 tests in 0.000s

i have ran python manage.py test -v 2 an the output is this

Skipping setup of unused database(s): default.
System check identified no issues (0 silenced).

----------------------------------------------------------------------
Ran 0 tests in 0.000s
OK

It is not creating a database or even running the tests in my file, i do not know what is wrong. This is my first time running tests.

Answer 1

have you defined function name with, test_ as prefix? like below

def test_your_function()

else every settings looks fine

Answer 2

I've seen the problem. I had a class method decorator on top my class instead of the function that has cls.

Answer 3

This just got me. You might also be importing the wrong test case.

If you import:

from unittest import TestCase

rather than

from django.test import TestCase

It won't create anything.
