我刚接触保险，遇到了一个奇怪的问题。我的报道将我的虚拟环境站点包考虑在内。下面是覆盖运行的输出:
coverage run test.py

下面是我的项目目录的结构，位于home目录下:

我一开始把虚拟环境放在项目目录中，现在用virtualenvwrapper把它移到了~/Envs，但是问题仍然存在。Run.py和test.py在任何方面都不特殊，它们都是从atcatalog中导入app。我还试图找到省略虚拟环境目录的方法，但google没有给出答案(令人惊讶)。我不认为覆盖的目的是测试已经测试好的站点包。所以我将把它们从运行中排除。
我怎样才能在测试我的站点包时避免覆盖?
多亏了tknickman，我明白了:使用
coverage run --source <path to project dir> test.py
或者创建一个配置文件.coveragerc，它驻留在运行coverage的目录中，包含以下内容:
[run]
source =
<path to project dir>
表示您没有将虚拟环境安装在项目目录下。如果虚拟环境安装在项目目录下，可以使用
coverage run --source <project path> --omit <pattern> test.py
注意，省略需要一个像
这样的文件模式~/projectdir/venv/*
而不是路径
对应的。coveragerc看起来像这样:
[run]
source=
<path to project dir>
omit=
<path to project dir>/<name of virtual env>/*
我仍然认为像标准库的包一样，任何安装在site-packages下的包都不应该被默认覆盖。
尝试使用py。测试，然后在setup.cfg文件中指定测试选项。首先需要pip安装pytest。
例如:[pytest]
norecursedirs = build docs/_build *.egg .tox *.venv
python_files = tests/functional* tests/integration*
addopts =
#--verbose
--tb short
# Turn on --capture to have brief, less noisy output
# You will only see output if the test fails
# Use --capture no if you want to see it all or have problems debugging
--capture fd
# --capture no
# show extra test summary info as specified by chars (f)ailed, (E)error, (s)skipped, (x)failed, (X)passed.
- rfEsxX
--junitxml junit.xml
--cov workspace --cov-report xml --cov-report term-missing
您可以阅读更多关于配置py的信息。测试在这里:https://pytest.org/latest/customize.html
在您的setup.cfg文件中包括:
[coverage:run]
omit=*/site-packages/*,*/tests/*,*/.eggs/*
如果使用pytest，您可以指定setup.cfg中要测试的独占路径或文件(参见文档):
[pytest]
# a directory
testpaths = tests
# exact file(s)
python_files = tests/test1.py tests/test2.py
看起来如果你包括python_files和testpaths参数，那么python_files将只被使用。
