java - 为什么我关于该元素包含某个字符串的断言失败了，即使它存在？

Question

主方法末尾的断言失败，即使该字符串包含在元素内，至少根据我在断言之前执行的控制台写入行。

谁能帮我弄清楚为什么该断言失败了？我已经无计可施了。简直就是把我的头发拔出来。

抱歉，如果有点困惑，我是 Java 新手。

在断言中，您在 WebElement 上调用 toString()，它返回如下内容:

[[[[[[ChromeDriver: chrome on LINUX (084b45f48be31410009e34b87903f54a)] ->     id: order-summary]] -> xpath: .//a[(@href='/a0Gf40000005CcuEAE')]]] -> xpath: ../../../..]

就像 Andy 指出的那样，您应该使用 itemParentRow.getText()。
