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

github仓库地址https://github.com/anapaulagomes/pytest-picked

--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

>git status
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

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

        .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。

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']
Changed test folders... 0. []
