Question

我是py.test的新手，请让我知道如何在PyScripter编辑器中运行py.test。我试过了这种方式，但它不起作用。

import pytest

def func（x）：返回x + 1

def test_answer（）：断言func（3）== 5

pytest.main（）

并且在运行上述脚本时出现错误

请帮助我

Answer 1

脚本似乎是错误的，据我所知pytest.main可以使用如果你想你的pytest应该由python解释器运行。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test_sample

的python文件中使用以下代码

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

这应该可以解决您的问题

如果您不希望python运行您的pytests，您可以配置pyscripter runner由pytests通过工具运行 - > gt;配置工具然后添加pytests命令行参数。然后你可以从工具中运行pytest。默认情况下，pyscripter使用python口译员作为跑步者

Answer 2

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

Answer 3

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

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

应该特别安装包含TerminalWriting代码的“py”lib。如果这不起作用，请file an file使用您正在使用的确切环境/ PyScripter版本。还有“import py; print py。 version ”的值。

Answer 4

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 运行 - ＆gt; Python引擎 - ＆gt;内部 运行测试，它应该工作。 Somtime pyscripter没有接收到更改，您可能必须重新初始化python引擎（Ctrl + F2）
