我们在测试时可能都见过这个屏幕，您所需要的只是一个带有自签名证书的 HTTPS 站点，然后您会看到“此网站的安全证书有问题”屏幕，这需要您单击链接才能继续。
对于 Watir，这不是问题，我可以像处理任何其他网页一样自动化屏幕，根据其文本或 ID 值单击链接。
使用 Watir-Webdriver 就好像 HTML 中的任何内容都无法识别。我并不孤单看到这个问题
这不仅仅是尝试单击链接，几乎您在这里尝试的任何操作都会在此页面上失败，即使是一个简单的功能，例如puts browser.text将返回一个错误。
Selenium::WebDriver::Error::NoSuchElementError: Unable to find element with tag name == body
您可以查看源代码，使用开发人员工具，或者让浏览器元素吐出它的 HTML，并清楚地看到该死的 body 标签就在那里，但 Webdriver 由于某种原因对此视而不见。
我不知道这是线索还是转移注意力，但我知道 webdriver 在底层使用了大量的 XPATH，而且我相信 XPATH 是区分大小写的。在这方面，当我使用时，我看到一些非常不寻常的东西puts browser.html与此页面相比，每个标签名称都是全大写的。无论如何，有点不寻常但合法有效的 HTML。使用browser.html其他页面上显示小写标签。这可能是导致 webdriver 此页面出现如此多问题的原因吗？
对于如何让 webdriver 查看链接元素以便我可以单击它，有人有任何好主意吗？
