pytest文档59-运行未提交git的用例(pytest-picked)

从零开始学自动化测试 2020-09-17 10:48

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

>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

>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

>pytest --picked=first

—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

>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

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