java - Selenium 网络驱动程序 : how to verify that there is a heading titled “Download” on the page wrapped in

Question

我应该使用哪个断言？请举个例子好吗？

代码当前打开 selenium 网站并单击“下载”链接。

在下载页面上有一个名为“下载”的 h2 标题。

<h2>Downloads</h2>

如何验证是否存在包含文本“下载”的标题并且该标题被 h2 标签包围？

如果我无法将断言行添加到“测试”方法中，请您帮我弄清楚如何在下面的代码中创建和调用所需的方法。我是java和selenium的新手。感谢您提供的任何帮助。

  private String closeAlertAndGetItsText() {
    try {
      Alert alert = driver.switchTo().alert();
      String alertText = alert.getText();
      if (acceptNextAlert) {
        alert.accept();
      } else {
        alert.dismiss();
      }
      return alertText;
    } finally {
      acceptNextAlert = true;
    }
  }
}

您可以使用 xpath 和 findElements 来实现此目的:

@Test
public void testGuayaki() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.linkText("Download")).click();

    List<WebElement> downloadHeader = driver.findElements(By.xpath("//h2[contains(text(), 'Downloads')]"));
    if(downloadHeader.size() > 0)
    {
        System.out.println("Found h2 header Downloads");
    }
}

如果要进行精确匹配，可以修改xpath如下:

//h2[text() = 'Downloads']
