运行Django测试时如何看到stdout？ [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，无论通过打印发送到标准输出不显示。当测试失败时，我会看到每个失败测试的stdout块，所以我猜Django陷阱它（但是当测试通过时不显示）。

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 TEST_RUNNER ，它正在使用一个项目特定的运行程序出鼻子。 Nose具有 -s 选项以阻止它捕获 stdout ，但如果我运行：

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 首先捕获它并抛出一个不这样的选项错误。 manage.py 的帮助没有提到这一点，但是我发现如果我运行：

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 test - -s

它忽略 -s ，让我在自定义赛跑者身上抓住它，将其传递给鼻子，没有问题。

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