跳过Python预提交unittest

Question

我想使用pre-commit为我的git项目处理git钩子。但是，当我使用它时，git commit命令会一直跳过unittest执行：

(smartexchange) trnbook:SmartExchange ale$ git commit -m "add pre-commit yaml config"
autopep8.............................................(no files to check)Skipped
unittest.............................................(no files to check)Skipped
[hook_precommit da26d1e] add pre-commit yaml config
1 file changed, 14 insertions(+)
create mode 100644 .pre-commit-config.yaml

预提交钩子手动执行的结果相同：

(smartexchange) trnbook:SmartExchange ale$ pre-commit install && python .git/hooks/pre-commit
pre-commit installed at .git/hooks/pre-commit
autopep8.............................................(no files to check)Skipped
unittest.............................................(no files to check)Skipped

我错过了什么？手动执行python -m unittest discover没问题，它执行4 unittest：

(smartexchange) trnbook:SmartExchange ale$ python -m unittest discover -s smartexchange/
....
----------------------------------------------------------------------
Ran 4 tests in 0.001s

OK

我已经阅读了预提交用户文档和以下答案：

Python pre-commit unittest faild

这是我的.pre-commit-config.yaml文件。你知道吗

repos:
-   repo: https://github.com/pre-commit/mirrors-autopep8
    rev: ''  # Use the sha / tag you want to point at
    hooks:
    -   id: autopep8
-   repo: local
    hooks:
    -   id: unittest
        name: unittest
        entry: python -m unittest discover 
        language: python
        'types': [python]
        additional_dependencies: []
        pass_filenames: false

我使用miniconda作为环境管理器。这里是我的conda list输出：

编辑：

Anthony's answer很好；不过，为了将来的参考，最好报告我用来运行带有选项--start-directory=path/to/python_module_folder的unittest命令（这里是docs about test-discovery）的修改后的配置：

    -   id: unittest
        name: unittest
        entry: python -m unittest discover
        language: python
        types: [python]
        args: [--start-directory=path/to/python_module_folder, --pattern=test_*.py]
        pass_filenames: false
        verbose: true

正如pre-commit documentation about argument pattern in hooks所报告的，其他参数应该在long format中。你知道吗

Answer 1

pre-commit只会在特定提交中为files which are staged运行钩子

此配置：

    -   id: unittest
        name: unittest
        entry: python -m unittest discover 
        language: python
        'types': [python]
        additional_dependencies: []
        pass_filenames: false

只在types: [python]文件匹配时运行（对于git commit这意味着需要更改python文件才能执行）

如果您想让它一直运行，可以使用always_run: true（不过，您可能可以节省一些时间）

如果您有任何python文件（将由types: [python]匹配），也可以使用pre-commit run all-files触发它

一些额外的提示

• 您不需要引用'types'（可以直接使用types，因为yaml支持裸词）
• additional_dependencies: []是默认值，您可以删除此行
