AttributeError: 'TestCase' object has no attribute 'Keys'

AttributeError: 'TestCase' object has no attribute 'Keys'是一个错误信息，意味着在TestCase对象中找不到'Keys'属性。根据给出的引用内容，我无法找到与该错误信息直接相关的引用内容。然而，根据常见的Python错误信息，这个错误通常发生在试图访问一个不存在的属性时。要解决这个问题，你可以检查代码中是否正确使用了'Keys'属性，并确保在TestCase对象中存在这个属性。如果你确定代码正确且没有任何问题，那么你可能需要进一步调查问题的原因，可能是由于其他地方的错误导致的。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
