我已经阅读了 xpath 教程并查看了许多其他帖子，因此我不确定我错过了什么.我只是想通过 xpath 找到以下元素:

I've been through the xpath tutorials and checked many other posts, hence I'm not sure what I'm missing. I'm simply trying to find the following element by xpath:

<input class="t-TextBox" type="email" test-id="test-username"/>

我尝试了很多东西，例如:

I've tried many things, such as:

element = findElement(By.xpath("//[@test-id='test-username']"));

错误是Expression is not a legal expression.

我在 MacBook 上使用 Firefox
