如何手动运行一个django TestCase对其他数据库？ [英] How do I run a django TestCase manually / against other database?

问题描述

我有一些方法写入一个 django.test.TestCase 对象，我想从
管理运行。 py shell 在我的真实数据库。但是当我尝试实例化TestCase对象来运行测试方法时，我收到这个错误：

I have some methods written into a django.test.TestCase object that I'd like to run from the manage.py shell on my real database. But when I try to instantiate the TestCase object to run the test method, I get this error:

ValueError: no such test method in <class 'track.tests.MentionTests'>: runTest

有没有办法实例化 TestCase 对象？还是有办法针对非测试数据库运行测试方法？

Is there a way to instantiate the TestCase objects? Or is there a way to run a test method against a non-test database?

推荐答案

这是我最近发现的一种方法。我还没有找到更好的东西。

Here's a method that I found recently. I haven't found anything better yet.

from django.test.utils import setup_test_environment
from unittest import TestResult
from my_app.tests import TheTestWeWantToRun

setup_test_environment()
t = TheTestWeWantToRun('test_function_we_want_to_run')
r = TestResult()
t.run(r)
r.testsRun # prints the number of tests that were run (should be 1)
r.errors + r.failures # prints a list of the errors and failures

根据文档，我们应该调用 setup_test_environment（） 手动运行测试。 django.test 使用 unittest 进行测试，所以我们可以使用 unittest的/ code> TestResult c>在运行测试时捕获结果。

According to the docs, we should call setup_test_environment() when manually running tests. django.test uses unittest for testing so we can use a TestResult from unittest to capture results when running the test.

在Django 1.2中， DjangoTestRunner 可用于更结构化的测试。我还没有尝试过。

In Django 1.2, DjangoTestRunner could be used for more structured testing. I haven't tried this yet though.
