pytest文檔59-運行未提交git的用例(pytest-picked)

前言

我們每天寫完自動化用例后都會提交到 git 倉庫，隨着用例的增多，為了保證倉庫代碼的干凈，當有用例新增的時候，我們希望只運行新增的未提交 git 倉庫的用例。
pytest-picked 插件可以實現只運行未提交到git倉庫的代碼。

pytest-picked

使用命令行安裝

pip install pytest-picked

可使用參數

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 參數

我們在已提交過 git 倉庫的用例里面新增了 2 個文件 test_new.py 和 test_new_2.py

cd到項目根目錄，使用 git status 查看當前分支狀態

>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個文件，使用 pytest --picked 運行用例

所有測試都將從已修改但尚未提交的文件和文件夾中運行。

--picked=first

首先運行修改后的測試文件中的測試，然后運行所有未修改的測試

--mode=PICKED_MODE

--mode 有2個參數可選 unstaged, branch, 默認是--mode=unstaged

git 文件的2個狀態

• untrack 沒加到git里面的新文件
• unstaged staged：暫存狀態, unstage就是未暫存狀態，也就是沒git add 過的文件

先弄清楚什么是 untrack 狀態，當我們 pycharm 打開 git 項目，新增一個文件的時候，會彈出詢問框：是否加到 git 文件

如果選擇是，文件會變綠色，也就是 unstage 狀態（沒git add 過）；選擇否，那就是一個新文件，未被加到當前分支的 git 目錄里面，文件顏色是棕色。
git status 查看當前分支的狀態,此時會看到 pytest_demo/test_3.py 是 Untracked files

Untracked files:

        .idea/
        pytest_demo/__pycache__/
        pytest_demo/test_3.py

運行 pytest --picked 會默認執行所有的 Untracked 文件和 not staged 文件，默認是--mode=unstaged。

>pytest --picked

如果我們只需運行當前分支上已經被暫存，但尚未提交的文件（不包含 Untracked files），使用 git diff 查看分支代碼的差異

>git diff --name-only master
pytest_demo/test_new.py
pytest_demo/test_new_2.py

運行 pytest --picked --mode=branch, 運行分支上已經被暫存但尚未提交的代碼

>pytest --picked --mode=branch

Changed test files... 2. ['pytest_demo/test_new.py', 'pytest_demo/test_new_2.py']
Changed test folders... 0. []
