Python覆盖率：运行1个以上的测试 [英] Python coverage: running more than 1 test

问题描述

我想知道是否有一种方法可以指定使用python coverage配置（ .coveragerc ）文件时要运行的多个测试文件。
如果不是从配置文件中获取，也许从命令行运行时可能吗？
目前，我正在使用3个不同的单元测试文件：

I'm wondering is there a way to specify more than 1 test file to run when using python coverage config (.coveragerc) file. If not from a config file, maybe it is possible when running from command line? At the moment, for 3 different unit tests files I'm using:

coverage run test1
coverage run -a test2
coverage run -a test3

可以短一些吗？
谢谢

Can it be any shorter? Thanks

推荐答案

编辑（2017-09-25）：如@ ned- batchelder在评论中表示，与 pytest .readthedocs.io / zh-CN / latest / rel = nofollow noreferrer>鼻子如果开始新项目，因为鼻子无法保持。

Edit (2017-09-25): As @ned-batchelder says in the comments, prefer pytest over nose if starting a new project, as nose is unmaintained.

看看封面文档，看起来 coverage 支持的模式是每个命令都运行一个特定的模块。

By taking a look at Coverage documentation, it looks like that the only mode that coverage supports is running a specific module with each command.

您可以使用测试框架，例如 鼻子 pytest ，以运行所有测试，并报告成功/失败率和总覆盖率。

You could use a testing framework, such as nose pytest, to run all your tests, and report the success/failure rate and the total coverage.

1）安装pytest，coverage和pytest-cov

1) Install pytest, coverage, and pytest-cov

pip install pytest
pip install coverage
pip install pytest-cov

2）使用-cov pytest 命令c>标记每个需要测量覆盖率的模块或软件包。例如：

2) Run the pytest commmand, using the --cov flag for every module or package whose coverage you need measured. For example:

pytest --cov=foo --cov=bar

样本输出：

Name     Stmts   Miss  Cover   Missing
--------------------------------------
bar.py       3      1    67%   5
foo.py       6      2    67%   9-11
--------------------------------------
TOTAL        9      3    67%

<$ c如果$ c> pytest 与模式 test _ *。py （或其他，更多信息此处）。

pytest will find your tests if they match the pattern test_*.py (or others, more info here).

1）安装鼻子和覆盖范围

1) Install nose and coverage

pip install nose
pip install coverage

2）运行 nosetests 命令，并使用- -with-coverage 标志

2) Run the nosetests command, with the --with-coverage flag

nosetests --with-coverage

样本输出（当使用单个模块foo.py时） ：

Sample output (when having a single module foo.py):

Name     Stmts   Miss  Cover
----------------------------
foo.py       6      2    67%
----------------------------------------------------------------------
Ran 1 test in 0.008s

OK

鼻子测试可以使用启发式方法自动找到您的测试。例如，如果将测试放在以 test 开头的文件名中，并通过继承 unittest.TestCase ， noestests 会找到它们。更多信息此处。


nosetests can automatically find your tests using some heuristics. For example, if you put your tests in filenames that start with test, and create your testcases by inheriting from unittest.TestCase, nosetests will find them. More info here.
