1.通過參數引用

@pytest.fixture()
def init_xx():
    print(".....初始化測試數據")
    with open("./test.txt", "w") as f:
        f.write("1")
class Test_xx:
    # 通過參數引用
    def test_xx(self, init_xx):
        with open("./test.txt", "r") as f:
            assert f.read() == "2"

2.通過函數引用

@pytest.fixture()
 
def init_xx():
    print(".....初始化測試數據")
    with open("./test.txt", "w") as f:
        f.write("1")
# 通過函數引用
@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.設置自動運行，測試類內的每個方法都調用一次函數

# 設置自動運行，測試類內的每個方法都調用一次函數
@pytest.fixture(scope="function", autouse="True")
# 設置自動運行，測試類內的只調用一次工廠函數
@pytest.fixture(scope="class
 
", autouse="True")
def init__xx():
    print("...初始化測試數據")
class Test_yy:
    def test_xx(self):
        print("...test_xx")
    def test_yy(self):
        print("...test_yy")

4.使用返回值，參數列表

# 使用返回值，參數列表
@pytest.fixture(params=[1, 2, 3])
def init_xx(request):
    return request.param
class Test_zz:
    # 開始
    def setup_class(self):
        print("...setup_class")
    # 結束
    def teardown_class(self):
        print("...teardown_class")
    # 參數引用
    def test_a(self, init_xx):
        assert init_xx == 4

練習：

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

# 練習（一）
class Test_SZ:
    # 開始
    def setup_class(self):
        self.driver = init_driver()
    # 結束
    def teardown_class(self):
        self.driver.quit()

    # 顯示等待
    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):
        # 進入設置，由聲音和振動滑動到飛行模式
        s_1 = self.wait_ele("xpath", "//*[contains(@text, ‘聲音和振動‘)]")
        e_1 = self.wait_ele("xpath", "//*[contains(@text, ‘飛行模式‘)]")
        self.driver.drag_and_drop(s_1, e_1)
        # 點擊勿擾模式
        self.wait_ele("xpath", "//*[contains(@text, ‘勿擾模式‘)]").click()

    @pytest.mark.usefixtures("t_index")
    # 業務一
    def test_001(self):
        # 改變勿擾規則
        off_on = self.wait_ele("id", "android:id/switchWidget")
        # 點擊開關
        off_on.click()
        # 點擊勿擾規則
        self.wait_ele("xpath", "//*[contains(@text, ‘勿擾規則‘)]").click()
        # 選擇僅限鬧鐘
        self.wait_ele("xpath", "//*[contains(@text, ‘僅限鬧鐘‘)]").click()
        # 取改變後的概要信息
        summary_text = self.wait_ele("id", "android:id/summary")
        assert "僅限鬧鐘" in summary_text.text, "失敗了..."

pytest高級用法，參數、函數、自動、返回值引用（九）
