运行 Django 测试时如何查看标准输出? [英] How do I see stdout when running Django tests?

问题描述

当我使用 ./manage.py test 运行测试时，我通过 print 发送到标准输出的任何内容都不会显示.当测试失败时，我会看到每个失败的测试都有一个stdout"块，所以我猜 Django 会捕获它(但在测试通过时不会显示它).

When I run tests with ./manage.py test, whatever I send to the standard output through print doesn't show. When tests fail, I see an "stdout" block per failed test, so I guess Django traps it (but doesn't show it when tests pass).

推荐答案

在 settings.py 中检查了 TEST_RUNNER，它使用了一个调用 Nose 的项目特定运行器.Nose 有 -s 选项来阻止它捕获 stdout，但是如果我运行:

Checked TEST_RUNNER in settings.py, it's using a project-specific runner that calls out to Nose. Nose has the -s option to stop it from capturing stdout, but if I run:

./manage.py test -s

manage.py 首先捕获它并抛出no such option"错误.manage.py 的帮助没有提到这一点，但我发现如果我运行:

manage.py captures it first and throws a "no such option" error. The help for manage.py doesn't mention this, but I found that if I run:

./manage.py 测试 -- -s

它忽略 -s 并让我在自定义跑步者的一侧捕获它，将其毫无问题地传递给 Nose.

it ignores the -s and lets me capture it on the custom runner's side, passing it to Nose without a problem.
