python - 通过 IDLE gui 运行 pytest

Question

我已经安装了 python 3.4.2，然后运行 ​​pip install -U pytest 来安装 pytest。

我有以下示例脚本:

# content of test_sample.py
import pytest

def func(x):
    return x + 1

def test_answer():
    assert func(3) == 4

当我在 IDLE 中按 F5 时，它似乎没有运行任何东西。如何通过 IDLE 测试我的脚本？

更新
我尝试添加 pytest.main()，但收到错误。

    raise ValueError("saved filedescriptor not valid anymore")
ValueError: saved filedescriptor not valid anymore

尝试将 pytest.main() 添加到脚本底部。

checkout :http://pytest.org/latest/usage.html#specifying-tests-selecting-tests对于一些不同的选项和语法。

编辑:在 IDLE 中运行时，您还需要像这样启动 pytest:pytest.main("--capture=sys")
