我对VSTS手动测试用例有问题。当我试图编辑一个时，我收到了一条错误消息，如下所示：
字典中已存在具有相同关键字的元素

只有当测试步骤包含参数时，我才会遇到此问题。刷新页面并重新打开测试用例后，颜色代码为黑色，并且不显示"保存"按钮。此外，...的下拉列表为空。
现有的测试很好，运行它们也是可能的。处理bug、用户故事和任务都很好。
屏幕截图可以在这里找到
有办法解决这个问题吗？
这是由参数名称"@length"引起的，请将其删除或重命名为其他名称，如"@length1"即可。
这似乎是VSTS的一个错误，我帮助您在MS Connect Page上创建了一个反馈，有关详细信息，请参阅此链接："字典中已经存在具有相同键的元素"错误发生在保存测试用例时，该测试用例包含名为"length"的参数。
