我在 try catch 块中使用 Contains text 通过 xpath 查找元素的方法返回 false

Question

我正在将 Webdriver 与 Python 一起使用我有一个方法可以检查网页上的项目名称是否包含预期值。
我的方法是 returning false。我期待它 return 正确。

我正在使用以下 xpath 检查元素是否包含项目名称

self.driver.find_element_by_xpath ('//*[contains(text(), %s)]' % project_name)

例如我正在寻找的项目名称值是 LADEMO_IE_05_21_1510_18_31

当我打印 xpath 时，以下输出在控制台中 returned & 它是那里（向下第 5 行）。

project_name_element = self.driver.find_element_by_xpath ('//*[contains(text(), %s)]' % project_name)

print project_name_element.text

输出结果如下：

JMeter_Reports_MegaOneCC

LAdemo

Sales Demo

Normal

LADEMO_IE_05_21_1510_18_31

LADEMO create a basic project test script - Selenium Webdriver/Python Automated test

LADEMO_IE_05_21_1510_20_44

    except AssertionError as e:
        self.verificationErrors.append(str(e))
    print "I am here in except AssertionError as e: administration_page.is_project_text_present2(project_name)"

控制台的输出是

错误我在这里除了 AssertionError as e: administration_page.is_project_text_present2(project_name)

我的方法是否有错误 return false 而不是 true？

Answer 1

问题可能出在您的时间延迟上。我想当您调用 administration_page.add_project(project_name) 时可能需要一些时间来添加项目并且您的下一行 administration_page.is_project_text_present2(project_name) 将 return false 因为页面还没有准备好。当您在控制台中尝试时，您总能找到它。为了验证这个想法，请添加一些 waiting before is_project_text_present2 方法。如果可行，我建议使用等待特定元素的方法。

Answer 2

我现在已经设法解决了这个问题。我更改了 XPath 以在 table Span class 单元格中查找项目名称。当它找到 LADEMO_IE_05_21_1510_18_31

的项目名称时，它现在 returns 为真

这是我的代码片段：

Pages\admin.py

    def is_project_name_present(self, project_name):
        try:
            test = self.driver.find_element_by_xpath('//span[contains(@class, "linkhover")][text()= "%s"]' % project_name)
        except NoSuchElementException, e:
            return False
        return project_name in test.text # Check if the project name is in the list of projects (list of projects is in the html table, /td class span

TestCases\AdministrationPage_TestCase.py

administration_page.is_project_name_present(project_name)
    assert administration_page.is_project_name_present(project_name), "project name " + project_name + "not found"

我在 try catch 块中使用 Contains text 通过 xpath 查找元素的方法返回 false
