我尝试使用www.example.com _screenshot（）方法保存selenium python项目中失败测试用例的屏幕截图driver.save。我指定了我的文件夹作为参数。但是在我的项目中看不到失败的屏幕截图。以下是代码。

self.driver.save_screenshot(".//Screenshots//"+"test_homePageTitle.png")

以下是绝对路径-/Users/cherry/Documents/Selenium pj/nopcommerceApp2/Screenshots
我想将失败的测试用例保存为特定文件夹中的屏幕截图
下面是完整的代码：

import time
from pageObjects.loginPage import LoginPage
from utilities.readProperties import ReadConfig

class Test_001_Login:
    baseURL = ReadConfig.getApplicationURL()
    username = ReadConfig.getUseremail()
    password = ReadConfig.getPassword()

    def test_homePageTitle(self, setup):
        self.driver = setup
        self.driver.get(self.baseURL)
        act_title = self.driver.title
        self.driver.close()
        if act_title == "Your store. Login":
            assert True
        else:
            time.sleep(5)
            # self.driver.save_screenshot("./nopcommerceApp2/Screenshots" + "test_homePageTitle.png")
            self.driver.save_screenshots('.//Screenshots//"+"test_homePageTitle.png')
            self.driver.close()
            assert False

    def test_login(self, setup):
        self.driver = setup
        self.driver.get(self.baseURL)
        time.sleep(10)
        self.lp = LoginPage(self.driver)
        self.lp.setUserName(self.username)
        self.lp.setPassword(self.password)
        self.lp.clickLogin()
        act_title = self.driver.title
        self.driver.close()
        if act_title == "Dashboard / nopCommerce administration":
            assert True
        else:
          time.sleep(5)
            self.driver.save_screenshot(".\\Screenshots\\" + "test_login.png")
            self.driver.close()
            assert False
