为什么我断言即使元素存在某个元素也包含某个String也会失败？

Question

即使该字符串包含在元素中，main方法末尾的断言也会失败，至少根据我在断言之前执行的控制台写入行而言。

谁能帮我弄清楚为什么该断言失败了？ 我机智的尽头。 从字面上拉我的头发。

很抱歉，如果是一团糟，我是Java的新手。

    this._price = price;
    this._itemID = itemID;
    this._itemDisplayName = itemDisplayName;

在断言中，您正在WebElement上调用toString() ，返回的内容如下：

[[[[[[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() 。
