Question

我无法以我想要的方式导入我的模块进行测试。我在2.7.2

的virtualenv中运行所有这些

我有一个像

这样的目录结构

/api
    /api
        __init__.py
        my_module.py
    /tests
        my_module_test.py

我将PYTHONPATH设置为/ Path / api /。我将CD刻录到/ Path / api并运行以下

 py.test tests/my_module_test.py

在以下情况下不起作用：

当我在my_module_test.py from api.my_module import my_function

它适用于以下情况：

当我在my_module_test.py from my_module import my_function

为什么我无法像案例1那样导入我的模块？

Answer 1

我使用 PYTHONPATH 作为

PYTHONPATH=`pwd` py.test tests/my_module_test.py

Answer 2

从py.text文档中，您应首先安装。：

pip install -e .

Answer 3

我创建这个作为你的问题的答案和我自己的困惑。我希望它有所帮助。请注意Private Sub returnFiletoSS() ' This Background worker Process . TestWorker = New BackgroundWorker TestWorker.WorkerReportsProgress = True TestWorker.WorkerSupportsCancellation = True TestWorker.RunWorkerAsync() End Sub ' This event handler deals with the results of the background operation. Private Sub TestWorker_RunWorkerCompleted(ByVal sender As Object, ByVal e As RunWorkerCompletedEventArgs) Handles TestWorker.RunWorkerCompleted ' First, handle the case where an exception was thrown. If (e.Error IsNot Nothing) Then MessageBox.Show(e.Error.Message) ElseIf e.Cancelled Then ' Next, handle the case where the user canceled the operation. ' Note that due to a race condition in the DoWork event handler, ' the Cancelled flag may not have been set, even though ' CancelAsync was called. Form2.resultLabel("Canceled") Else ' Finally, handle the case where the operation succeeded. ' Form2.resultLabel(e.Result.ToString()) lastRecord = True ' objWriter1.Close() 'Tried closing writer here, but errors. End If命令行和PYTHONPATH中的py.test。

示例项目为here，以及以下内容：

tox.ini：

mymodule.py

import boto3 def stuff(): print "Yep!"：

tests/text_syntax_errors.py

import boto3 import mymodule # Define a basic test that actually doesn't do much. # I just wanted more than zero tests def test_one_equals_one(): assert 1 == 1：

tox.ini

[tox] skipsdist = True envlist = py27 [flake8] max-line-length = 119 [testenv] deps= -r{toxinidir}/requirements.txt commands=py.test setenv = PYTHONPATH = {toxinidir}：

requirements.txt

来自我的boto3 pytest：

如何运行这些示例

我测试代码的最初动机是我在脚本中拼错了一个导入的模块，我正在为工作而写。

如果您修改README.md并从“mymodule.py”中删除b，您会看到以下命令失败。这是一件好事。同样，如果您希望看到实际测试失败，只需修改boto3并将tests/test_syntax_errors.py更改为1 == 1。

<强> py.test

1 == 0

<强> TOX
