fixture+yield用法

import pytest


class TestCase:
    def setup_class(self):
        print("setup_class：所有用例执行之前")

    def setup_method(self):
        print("setup_method:  每个用例开始前执行")

    def teardown_method(self):
        print("teardown_method:  每个用例结束后执行")

    def teardown_class(self):
        print("teardown_class：所有用例执行之后")

    @pytest.fixture(scope="class")
    def fixture_class(self):
        """class级别"""
        print("fixture_class：执行class级别装饰器")
        yield
        print("fixture_class：恢复class级别设置")

    @pytest.fixture(scope="function")
    def fixture_function(self):
        """用例级别"""
        print("fixture_function：执行用例级别装饰器")
        yield
        print("fixture_function：恢复用例级别设置")

    def test_A(self, fixture_function):
        print("用例A")
        assert True

    def test_B(self):
        print("用例B")
        assert True

    def test_C(self, fixture_function, fixture_class):
        print("用例C")
        assert True

    def test_D(self):
        print("用例C")
        assert True
