import sys

import pytest

class TestDemo:

    def test_demo1(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    def test_demo3(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    def test_demo2(self):
        x = 'hello'
        assert hasattr(x,"check")


if __name__ == "__main__":
    pytest.main(['-v', '-s','test_2.py'])

看着默认执行顺序是代码中函数的顺序

更改用例的执行顺序，可以安装包 pip install pytest-ordering

按序执行@pytest.mark.run(order=x)

import sys

import pytest

class TestDemo:
    @pytest.mark.run(order=1)
    def test_demo1(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    @pytest.mark.run(order=3)
    def test_demo3(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    @pytest.mark.run(order=2)
    def test_demo2(self):
        x = 'hello'
        assert hasattr(x,"check")


if __name__ == "__main__":
    pytest.main(['-v', '-s','test_2.py'])

依赖执行

pip install pytest-dependency

用例默认执行顺序是test1-->test2-->test3，test2依赖test1，test3依赖test2。

test1通过才会执行test2，test2通过才会执行test3，如果test1失败，则后续依赖的用例跳过，

如果依赖的用例还未执行，也会跳过

import sys

import pytest

class TestDemo:
    @pytest.mark.dependency(name="test1")
    def test_demo1(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    @pytest.mark.dependency(name="test3",depends=['test2'])
    def test_demo3(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    @pytest.mark.dependency(name="test2",depends=['test1'])
    def test_demo2(self):
        x = 'hello'
        assert hasattr(x,"check")


if __name__ == "__main__":
    pytest.main(['-v', '-s','test_2.py'])

test_demo2未执行，test_demo3跳过

import sys

import pytest

class TestDemo:
    @pytest.mark.dependency(name="test1")
    @pytest.mark.run(order=1)
    def test_demo1(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    @pytest.mark.dependency(name="test3",depends=['test2'])
    @pytest.mark.run(order=3)
    def test_demo3(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    @pytest.mark.dependency(name="test2",depends=['test1'])
    @pytest.mark.run(order=2)
    def test_demo2(self):
        x = 'hello'
        assert hasattr(x,"check")


if __name__ == "__main__":
    pytest.main(['-v', '-s','test_2.py'])

顺序对了，但是test_demo2失败，test_demo3跳过

import sys

import pytest

class TestDemo:
    @pytest.mark.dependency(name="test1")
    @pytest.mark.run(order=1)
    def test_demo1(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    @pytest.mark.dependency(name="test3",depends=['test2'])
    @pytest.mark.run(order=3)
    def test_demo3(self):
        x = "hello world"
        print(f"{x} python")
        assert 'h' in x

    @pytest.mark.dependency(name="test2",depends=['test1'])
    @pytest.mark.run(order=2)
    def test_demo2(self):
        x = 'hello'
        assert hasattr(x,"replace")


if __name__ == "__main__":
    pytest.main(['-v', '-s','test_2.py'])

顺序对，依赖对
