python - 如何在 PyScripter 中运行 Py.test

Question

我是 py.test 的新手，请告诉我如何在 PyScripter 编辑器中运行 py.test。我已经尝试过 belwo 方式，但它不起作用。

导入测试

定义函数(x): 返回 x + 1

def test_answer(): 断言 func(3) == 5

pytest.main()

在运行上面的脚本时我得到一个错误提示

请帮帮我

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。您需要在一个目录下进行测试。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 文件中包含以下代码

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

这应该可以解决您的问题

如果您不想让 python 运行您的 pytests，您可以通过 tools-->configure tools 将 pyscripter runner 配置为由 pytests 运行，然后添加 pytests 命令行参数。然后你可以从工具运行 pytest。默认情况下，pyscripter 使用 python 解释器作为运行器
