我使用try-catch块中的Contains text通过xpath查找元素的方法是返回fals

Question

我在Python中使用Webdriver 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。
我的方法是返回false。我原以为它会变成真的。在

我使用下面的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，我要查找的项目名称值是LADEMO_IE_05_21_1510_18_31

当我打印xpath时，控制台返回以下输出 在那里（第五排）。在

^{pr2}$

输出如下：

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

Answer 1

问题可能出在你的时间延迟上。我想当您调用administration_page.add_project(project_name)时，添加项目可能需要一些时间，下一行administration_page.is_project_text_present2(project_name)将返回false，因为页面还没有准备好。当你在控制台中尝试时，你总能找到它。 为了验证这个想法，请添加一些waiting beforeis_project_text_present2方法。如果可以的话，我建议使用waiting to the specific element方法。在

Answer 2

我现在已经设法解决了。我更改了XPath以在表Span类单元中查找项目名称。 现在，当找到项目名称LADEMO_IE_05_21_1510_18_31时，它将返回true

下面是我的代码片段：

页数\管理员py在

    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
