我是 py.test 的新手，请告诉我如何在 PyScripter Editor 中运行 py.test。我已经尝试过以下方式，但它不起作用。

导入pytest

def func(x): 返回 x + 1

def test_answer(): 断言 func(3) == 5

pytest.main()

在运行上述脚本时，我收到一条错误消息 

Traceback (most recent call last):

该脚本似乎是错误的，据我所知，如果您希望 pytest 应该由 python 解释器运行，可以使用 pytest.main。您需要在目录下进行测试。例如，您的 pytest 文件名为 test_sample，其中包含以下内容 ===================================pytests/test_sample ================================

    import pytest
    def func(x): return x + 1
    def test_answer(): assert func(3) == 5

==================================================== ================================ 然后你可以在运行你的test_sample的python文件中有以下代码

   pytest.main(args=['-s', os.path.abspath('pytests')])

这应该可以解决您的问题

如果你不想让 python 运行你的 pytests，你可以通过 tools-->configure tools 配置 pyscripter runner 以由 pytests 运行，然后添加 pytests 命令行参数。然后，您可以从工具中运行 pytest。默认情况下 pyscripter 使用 python 解释器作为运行器

您可以在 pydev 中使用 pytest：
http ://pypi.python.org/pypi/pytest-pydev/0.1

import pytest,os
os.chdir("C:\Users\Public\Documents\Development\Python\<test_pytest.py>") #your file location
pytest.main(['-s', 'test_pytest.py'])

保存文件。在 Pyscripter 上转到Run-->Python Engine--> Internal Run the test ，它应该可以工作。Somtime pyscripter 不接受更改，您可能需要重新初始化 python 引擎 (Ctrl+F2)

似乎 PyScripter 设置了一些 pytest 无法识别的 sys.stdout 流。我只是试图从 pytest 方面改进处理。您可以尝试使用它：

pip install -i http://pypi.testrun.org -U pytest

特别是还应该安装包含 TerminalWriting 代码的“py”库。如果这不起作用，请使用您正在使用的确切环境/PyScripter 版本归档一个文件。还有“import py ; print py.version”的值。

HTH，霍尔格
