单元测试 - 针对程序中最小的功能模块(函数和方法)的测试
|
|||
|
测试方法:
|
|||
|
- 白盒测试:程序自己写的测试
|
|||
|
- 黑盒测试:测试人员或QA,不知道代码实现细节,只关注功能
|
|||
|
编写Python单元测试 - 定义类继承TestCase,写测试方法(test_开头)
|
|||
|
执行单元测试:
|
|||
|
- unittest.main()
|
|||
|
- python3 -m unittest test_example01.py
|
|||
|
第三方库 - nose2 / pytest
|
|||
|
pip install pytest pytest-cov
|
|||
|
pytest -v --cov
|
|||
|
------------------------------
|
|||
|
pip install nose2 cov-core
|
|||
|
nose2 -v -C
