我是Selenium webdriver的新手。我正在开发一个应用程序，其中单击按钮将弹出一个窗口以创建新文件夹。在此弹出窗口中，我们需要填写几个输入字段，选中几个框，然后单击“创建”按钮以创建文件夹。我试图点击复选框，然后点击创建。复选框没有名称，文本，标签。我尝试使用CSS选择器，然后该元素的以下xpath，其中没有这些正在工作。当使用xpath运行时，我收到一个异常错误，指出“无法找到元素”。
driver.findElement(By.xpath("//div[9]/div[2]/div/div/span/div/div/div[2]/table/tbody/tr/td[2]/table/tbody/tr/td[2]/input"));
这是弹出窗口复选框图像的链接

答案 0 :(得分：2)
首先，如果您正在测试复杂的Web应用程序，下面的答案将不会那么优雅。如果您确实想要对ExtJS ui进行测试，请将类名添加到相关元素中。如果你不能让开发人员这样做，生活将是悲惨的。
第1步：通过cssSelector .x-window或xpath //*[contains(@class, 'x-window')]找到窗口
第2步：找到所有复选框，cssSelector input[id^='checkboxfield']或xpath //input[starts-with(@id, 'checkboxfield')]。或者，您也可以首先找到table[id^='checkboxfield']，然后在里面找到input，但逻辑是相同的。
第3步：索引您想要的
List<IWebElement> checkboxes = driver.findElements(By.cssSelector(".x-window input[id^='checkboxfield']"));
//checkboxes.size() here should be six in your case?
checkboxes[0].click();
我建议您学习如何有效地使用xpath或cssSelector。但是，我认为这个答案仍然不优雅的原因是因为索引元素列表并不是一种稳定的方法。
每当UI更改时，您的测试都会失败。如果您有该复选框的自定义类名，则会更容易，因为您可以通过其唯一的类名找到此特定复选框（例如checkbox-owner-write）。
