如何使用鼻子测试将模拟包从python覆盖率报告中排除

本文介绍了如何使用鼻子测试将模拟包从python覆盖率报告中排除的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我目前尝试使用模拟库在python中编写一些基本的鼻子单元测试.

I currently try to use the mock library to write some basic nose unittests in python.

完成一些基本示例后，我现在尝试使用nosetests --with-coverage，现在我有了模拟程序包，并且尝试模拟"的程序包显示在覆盖率报告中.有可能排除这些吗?

After finishing some basic example I now tried to use nosetests --with-coverage and now I have the mock package and the package I tried to 'mock away' are shown in the coverage report. Is there a possibility to exclude these?

这是我要测试的课程:

from imaplib import IMAP4 class ImapProxy: def __init__(self, host): self._client = IMAP4(host)

和测试用例: 从模拟导入补丁

And the testcase: from mock import patch

from ImapProxy import ImapProxy class TestImap: def test_connect(self): with patch('ImapProxy.IMAP4') as imapMock: proxy = ImapProxy("testhost") imapMock.assert_called_once_with("testhost")

我现在得到nosetests --with-coverage

. Name Stmts Miss Cover Missing ------------------------------------------ ImapProxy 4 0 100% imaplib 675 675 0% 23-1519 mock 1240 810 35% [ a lot of lines]

是否可以通过--cover-package=PACKAGE

感谢Ned Batchelder我现在了解.coveragerc文件，谢谢！！

Thanks to Ned Batchelder I now know about the .coveragerc file, thanks for that!

我创建了一个.coveragerc文件，其内容如下:

I created a .coveragerc file with the following content:

[report] omit = *mock*

现在，我在覆盖率报告中的模拟输出为:

Now my output for mock in the coverage report is:

mock 1240 1240 0% 16-2356

它不再涵盖模拟包，但仍在报告中显示.

It does not cover the mock package any longer but still shows it in the report.

如果有帮助，我会使用3.5.2版的Coverage.py.

I use Coverage.py, version 3.5.2 if this is any help.

推荐答案

创建一个.coveragerc文件，该文件排除了报告中不需要的内容: nedbatchelder/code/coverage/config.html

Create a .coveragerc file that excludes what you don't want in the report: nedbatchelder/code/coverage/config.html
