pytest文档59-运行未提交git的用例(pytest-picked)
前言
我们每天写完自动化用例后都会提交到 git 仓库，随着用例的增多，为了保证仓库代码的干净，当有用例新增的时候，我们希望只运行新增的未提交 git 仓库的用例。
pytest-picked 插件可以实现只运行未提交到git仓库的代码。
pytest-picked
使用命令行安装
pip install pytest-picked
可使用参数
picked:
--picked=[{only,first}]
Run the tests related to the changed files either on their own, or first
--mode=PICKED_MODE Options: unstaged, branch
使用示例：
$ pytest --picked
$ pytest --picked=first
$ pytest --picked --mode=branch
$ pytest --picked --mode=unstaged # default

—picked 参数
我们在已提交过 git 仓库的用例里面新增了 2 个文件 test_new.py 和 test_new_2.py
cd到项目根目录，使用 git status 查看当前分支状态

On branch master
Your branch is up-to-date with 'origin/master'.
Changes to be committed:
(use "git reset HEAD <file>..." to unstage)
new file: pytest_demo/test_new.py
new file: pytest_demo/test_new_2.py
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: pytest_demo/test_new.py
modified: pytest_demo/test_new_2.py
可以看到有2个文件，使用 pytest --picked 运行用例
>pytest --picked

所有测试都将从已修改但尚未提交的文件和文件夹中运行。
—picked=first
首先运行修改后的测试文件中的测试，然后运行所有未修改的测试

—mode=PICKED_MODE
--mode 有2个参数可选 unstaged, branch, 默认是--mode=unstaged
git 文件的2个状态
untrack 没加到git里面的新文件
unstaged staged：
暂存状态, unstage就是未暂存状态，也就是没git add 过的文件
先弄清楚什么是 untrack 状态，当我们 pycharm 打开 git 项目，新增一个文件的时候，会弹出询问框：是否加到 git 文件
如果选择是，文件会变绿色，也就是 unstage 状态（没git add 过）；选择否，那就是一个新文件，未被加到当前分支的 git 目录里面，文件颜色是棕色。
git status 查看当前分支的状态,此时会看到 pytest_demo/test_3.py 是 Untracked files

Your branch is up-to-date with 'origin/master'.
Changes to be committed:

new file: pytest_demo/test_new_2.py

Untracked files:
(use "git add <file>..." to include in what will be committed)
.idea/
pytest_demo/__pycache__/
pytest_demo/test_3.py
运行 pytest --picked 会默认执行所有的 Untracked 文件和 not staged 文件，默认是--mode=unstaged。
>pytest --picked
Changed test files... 3. ['pytest_demo/test_new.py', 'pytest_demo/test_new_2.py', 'pytest_demo/test_3.py']
Changed test folders... 2. ['.idea/', 'pytest_demo/__pycache__/']

如果我们只需运行当前分支上已经被暂存，但尚未提交的文件（不包含 Untracked files），使用 git diff 查看分支代码的差异
>git diff --name-only master
pytest_demo/test_new.py
pytest_demo/test_new_2.py
运行 pytest --picked --mode=branch, 运行分支上已经被暂存但尚未提交的代码
>pytest --picked --mode=branch
Changed test files... 2. ['pytest_demo/test_new.py', 'pytest_demo/test_new_2.py']
