Selenium WebDriver findElement(By.xpath())不适合我

Question

我已经通过xpath教程并检查了许多其他帖子,因此我不确定我缺少什么.我只是想通过xpath找到以下元素:

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

我尝试了很多东西,例如:

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

错误是Expression is not a legal expression.

我在MacBook上使用Firefox

任何建议将不胜感激.

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