pytest-choose

English | 简体中文

为pytest提供基于文本文件收集用例的能力

v0.1.0升级说明：

• v0.0.x版本升级至v0.1.0版本时，请将原--fc-path参数更改为--fc-allow-path
• 升级后规则文件不强制要求完全包含class function块，按需编写即可

1.安装

pip install pytest-choose

2.参数说明

3.过滤文件模板

3.1.JSON

{
  "@说明": [
    "@注释以‘@’符开头声明"
  ],
  "path": [
    "@下方填写用例路径",
    "TestClassName"
  ],
  "marker": [
    "@下方填写需要选中的测试tag",
    "test_function_name"
  ],
  "class": [
    "@下方填写需要执行的测试类",
    "TestClassName"
  ],
  "function": [
    "@下方填写需要执行的测试方法",
    "test_function_name"
  ]
}

4.示例

创建测试文件：

# test_demo.py
import pytest


class TestDemo:
    def test_demo_1(self):
        print(1)

    @pytest.mark.testt    
    def test_demo_2(self):
        print(2)

@pytest.mark.test
def test_demo_3():
    print(3)

def test_demo_4():
    print(4)

def test_demo_5():
    print(5)

def test_demo_6():
    print(6)

def test_demo_7():
    print(7)

4.1.基本使用

创建文件choose.json，用于选择用例:

{
  "class": [
    "TestDemo"
  ],
  "function": [
    "test_demo_2",
    "test_demo_3",
    "test_demo_4",
    "test_demo_5"
  ]
}

执行测试:

pytest --fc="on" --fc-allow-path="./choose.json" --fc-coding="utf-8"

测试结果如下:

======================= test session starts =======================
platform win32 -- Python 3.9.6, pytest-7.4.3, pluggy-1.3.0
rootdir: D:\Project\PytestDev\pytest-choose
plugins: choose-0.1.0
collecting ... 

[pytest-choose] <Allow list>: choose.json -> Successful use of rules
[pytest-choose] Filter 5 cases and collect 2 cases
collected 7 items

cases\test_choose.py ..                            [100%] 
======================== 2 passed in 0.03s ======================== 

4.2.黑名单过滤

创建文件filter.json，用于过滤用例:

{
  "function": [
    "test_demo_3",
    "test_demo_4",
    "test_demo_5"
  ]
}

执行测试:

pytest --fc="on" --fc-block-path="./filter.json" --fc-coding="utf-8"

测试结果如下:

======================= test session starts =======================
platform win32 -- Python 3.9.6, pytest-7.4.3, pluggy-1.3.0
rootdir: D:\Project\PytestDev\pytest-choose
plugins: choose-0.1.0
collecting ... 

[pytest-choose] <Block list>: filter.json -> Successful use of rules
[pytest-choose] Filter 3 cases and collect 4 cases
collected 7 items

cases\test_choose.py ....                          [100%] 
======================== 4 passed in 0.05s ======================== 

4.3.黑白名单过滤

• 当同时使用黑白名单时，过滤结果为两个规则的差集（{x∣x∈白名单,且x∉黑名单}）
• 当黑白名单无重合项时，默认黑名单失效。

创建文件choose.json，用于选择用例:

{
  "function": [
    "test_demo_2",
    "test_demo_3"
  ]
}

创建文件filter.json，用于过滤用例:

{
  "function": [
    "test_demo_3",
    "test_demo_4",
    "test_demo_5"
  ]
}

执行测试:

pytest --fc="on" --fc-allow-path="./choose.json" --fc-block-path="./filter.json" --fc-coding="utf-8"

测试结果如下:

======================= test session starts =======================
platform win32 -- Python 3.9.6, pytest-7.4.3, pluggy-1.3.0
rootdir: D:\Project\PytestDev\pytest-choose
plugins: choose-0.1.0


[pytest-choose] <Allow list>: choose.json -> Successful use of rules
[pytest-choose] <Block list>: filter.json -> Successful use of rules
[pytest-choose] Filter 6 cases and collect 1 cases
collected 7 items

cases\test_choose.py .                             [100%] 
======================== 1 passed in 0.04s ======================== 

4.4.多规则文件过滤

• 当传入规则文件不存在时，仅会抛出响应日志，不会中止测试
• 当传入同类型的多个规则文件时，生效规则为该类型所有规则文件的并集

创建文件choose.json，choose_1.json，用于选择用例:

{
  "function": [
    "test_demo_2",
    "test_demo_3"
  ]
}

{
  "function": [
    "test_demo_4"
  ]
}

创建文件filter.json，用于过滤用例:

{
  "function": [
    "test_demo_3",
    "test_demo_4",
    "test_demo_5"
  ]
}

同时传入不存在的文件filter_1.json，执行测试:

pytest --fc="on" --fc-allow-path="./choose.json" --fc-allow-path="./choose_1.json" --fc-block-path="./filter.json" --fc-block-path="./filter_1.json" --fc-coding="utf-8"

测试结果如下:

======================= test session starts =======================
platform win32 -- Python 3.9.6, pytest-7.4.3, pluggy-1.3.0
rootdir: D:\Project\PytestDev\pytest-choose
plugins: choose-0.1.0


[pytest-choose] <Allow list>: choose.json -> Successful use of rules
[pytest-choose] <Allow list>: choose_1.json -> Successful use of rules
[pytest-choose] <Block list>: filter.json -> Successful use of rules
[pytest-choose] <Block list>: filter_1.json -> No such file or directory
[pytest-choose] Filter 6 cases and collect 1 cases
collected 7 items

cases\test_choose.py .                              [100%] 
======================== 1 passed in 0.04s ======================== 

4.5.用例路径及Tag过滤

• 当传入path参数中路径不存在时会在用例收集阶段触发对应异常
• Tag参数以and方式拼接

创建文件choose.json用于选择用例:

{
  "path": [
    "./cases/"
  ],
  "marker": [
    "test",
    "not testt"
  ],
  "function": [
    "test_demo_2",
    "test_demo_3"
  ]
}

测试结果如下:

======================= test session starts =======================
platform win32 -- Python 3.9.6, pytest-7.4.3, pluggy-1.3.0
rootdir: D:\Project\PytestDev\pytest-choose
plugins: choose-0.2.0
collecting ... 

[pytest-choose] <Allow list>: choose.json -> Successful use of rules
[pytest-choose] Filter 5 cases and collect 2 cases
[pytest-choose] Use marker: test and not testt
[pytest-choose] Use case path: ['./cases/']
collected 7 items / 1 deselected / 6 selected                                                                                                                                                             

cases\test_choose.py .                              [100%] 
======================== 1 passed in 0.04s ========================
