【pytest-3】python代码中调用pytest

1.pycharm配置pytest

File——>settings——>Python Intergrated Tools—>Default test runner设置成pytest

 

2.pycharm写pytest代码

运行test_a.py

import pytest
class Test_class:
    def test_one(self):
        a = "hello"
        assert hasattr(a,"tock")
    def test_three(self):
        c = "hello"
        d = "o"
        assert d in c
    def test_four(self):
        c = 3+6
        d = 4+4
        assert c==d

if __name__ == '__main__':
    pytest.main("-p test_a.py")

运行结果：

3.配置好了之后，直接右击运行

 3.1如果脚本是以xx.py,也可以直接运行

3.2.如果py脚本不是以test_*.py的格式，也可以直接运行。

3.3.如果是unittest，也可以当作pytest去运行，pytest兼容unittest。

4.pytest.main(),main中参数

pytest.main():main中传入不同指令用以执行指定测试用例

• -s：显示程序中的print/logging输出。
• -v：丰富信息模式,输出更详细的用例执行信息。
• -q：简化控制台输出，安静模式。
• -k：关键字匹配，用and区分:匹配范围(文件名，类名，函数名)。
• -m：pytest -m ”标记“ 说明：执行特定的测试用例。

示例：

pytest.main(['-s','test_*.py'])#-s:显示程序中的print/logging输出
