• pytest文档3-pycharm运行pytest

    前言

    上一篇pytest文档2-用例运行规则已经介绍了如何在cmd执行pytest用例,平常我们写代码在pycharm比较多
    写完用例之后,需要调试看看,是不是能正常运行,如果每次跑去cmd执行,太麻烦,所以很有必要学习如何在pycharm里面运行pytest用例

    pycharm运行三种方式

    1.以xx.py脚本方式直接执行,当写的代码里面没用到unittest和pytest框架时,并且脚本名称不是以test_开头命名的,此时pycharm会以xx.py脚本方式运行

    2.当脚本命名为test_xx.py时,用到unittest框架,此时运行代码,pycharm会自动识别到以unittest方式运行

    3.以pytest方式运行,需要改该工程设置默认的运行器:file->Setting->Tools->Python Integrated Tools->项目名称->Default test runner->选择py.test

    备注:pytest是可以兼容unittest框架代码的

    pycharm写pytest代码

    1.在pycharm里面写pytest用例,先导入pytest

    # D:/YOYO/test_class.py

    import pytest
    
    class TestClass:
            def test_one(self):
                x = "this"
                assert 'h' in x
    
            def test_two(self):
                x = "hello"
                assert hasattr(x, 'check')
    
            def test_three(self):
                a = "hello"
                b = "hello world"
                assert a in b
    
    if __name__ == "__main__":
        pytest.main('-q test_class.py')
    

    运行结果

    .F.                                                                      [100%]
    ================================== FAILURES ===================================
    _____________________________ TestClass.test_two ______________________________
    
    self = <YOYO.test_class.TestClass object at 0x00000000039F9080>
    
        def test_two(self):
            x = "hello"
    >       assert hasattr(x, 'check')
    E       AssertionError: assert False
    E        +  where False = hasattr('hello', 'check')
    
    test_class.py:11: AssertionError
    ============================== warnings summary ===============================
    <undetermined location>
      passing a string to pytest.main() is deprecated, pass a list of arguments instead.
    
    -- Docs: http://doc.pytest.org/en/latest/warnings.html
    1 failed, 2 passed, 1 warnings in 0.06 seconds

    2.运行结果“.F. ” 点是代表测试通过,F是Fail的意思,1 warnings是用于pytest.main('-q test_class.py')里面参数需要传list,多个参数放list就不会有警告了

    pytest.main(['-q', 'test_class.py'])

    pycharm设置pytest

    1.新建一个工程后,左上角file->Setting->Tools->Python Integrated Tools->项目名称->Default test runner->选择py.test

    2.改完之后,再重新建个脚本(注意是先改项目运行方式,再写代码才能出来),接下来右键运行就能出来pytest运行了

    3.pytest是可以兼容unittest脚本的,之前写的unittest用例也能用pytest框架去运行
