pytest高级用法，参数、函数、自动、返回值引用（九）

1.通过参数引用

@pytest.fixture()
def init_xx():
    print(".....初始化测试数据")
    with open("./test.txt", "w") as f:
        f.write("1")
class Test_xx:
    # 通过参数引用
    def test_xx(self, init_xx):
        with open("./test.txt", "r") as f:
            assert f.read() == "2"

2.通过函数引用

@pytest.fixture()
def init_xx():
    print(".....初始化测试数据")
    with open("./test.txt", "w") as f:
        f.write("1")
# 通过函数引用
@pytest.mark.usefixtures("init_xx")
class Test_xx:
    def setup_class(self):
        print("...setup_class")
    def teardown_class(self):
        print("...teardown_class")
    def test_xx(self):
        with open("./test.txt", "r") as f:
            assert f.read() == "2"
    def test_yy(self):
        assert True

3.设置自动运行，测试类内的每个方法都调用一次函数

# 设置自动运行，测试类内的每个方法都调用一次函数
@pytest.fixture(scope="function", autouse="True")
# 设置自动运行，测试类内的只调用一次工厂函数
@pytest.fixture(scope="class", autouse="True")
def init__xx():
    print("...初始化测试数据")
class Test_yy:
    def test_xx(self):
        print("...test_xx")
    def test_yy(self):
        print("...test_yy")

4.使用返回值，参数列表

# 使用返回值，参数列表
@pytest.fixture(params=[1, 2, 3])
def init_xx(request):
    return request.param
class Test_zz:
    # 开始
    def setup_class(self):
        print("...setup_class")
    # 结束
    def teardown_class(self):
        print("...teardown_class")
    # 参数引用
    def test_a(self, init_xx):
        assert init_xx == 4

练习：

from init_driver.Init_driver import init_driver
from selenium.webdriver.support.wait import WebDriverWait
import pytest

# 练习（一）
class Test_SZ:
    # 开始
    def setup_class(self):
        self.driver = init_driver()
    # 结束
    def teardown_class(self):
        self.driver.quit()

    # 显示等待
    def wait_ele(self, type, xpt):
        if type == "id":
            return WebDriverWait(self.driver, 5, 1)
                .until(lambda x: x.find_element_by_id(xpt))
        if type == "xpath":
            return WebDriverWait(self.driver, 5, 1)
                .until(lambda x: x.find_element_by_xpath(xpt))
    @pytest.fixture()
    def t_index(self):
        # 进入设置，由声音和振动滑动到飞行模式
        s_1 = self.wait_ele("xpath", "//*[contains(@text, '声音和振动')]")
        e_1 = self.wait_ele("xpath", "//*[contains(@text, '飞行模式')]")
        self.driver.drag_and_drop(s_1, e_1)
        # 点击勿扰模式
        self.wait_ele("xpath", "//*[contains(@text, '勿扰模式')]").click()

    @pytest.mark.usefixtures("t_index")
    # 业务一
    def test_001(self):
        # 改变勿扰规则
        off_on = self.wait_ele("id", "android:id/switchWidget")
        # 点击开关
        off_on.click()
        # 点击勿扰规则
        self.wait_ele("xpath", "//*[contains(@text, '勿扰规则')]").click()
        # 选择仅限闹钟
        self.wait_ele("xpath", "//*[contains(@text, '仅限闹钟')]").click()
        # 取改变后的概要信息
        summary_text = self.wait_ele("id", "android:id/summary")
        assert "仅限闹钟" in summary_text.text, "失败了..."
