当前测试主要问题：
- 第一步生成的注释有时为空，例如CODE2。
- 生成拓展词的时候，有时会出现补 @param / @throw / @return 等情况。
- 预测的结果里，有时会引入新的掩码，例如 CODE2-3 attrURI。
- 一些不常见的缩写，即使是代码里有对应的全称，也预测不出来。例如 CODE2-2 nsme。
下文格式说明：
- 测试代码编号
- 测试代码本体
- 缩写词测试结果
- 缩写词=>全称
- 模型给出的结果
- 发现的一些额外问题或补测结果

- meth => method ✅
['Method to call', 'Method name', 'Method called', 'The method', 'Method', 'Method to invoke', 'Method to execute', 'Method invoked', 'Method object', '']- nsme => NoSuchMethodException ❎
['TODO', 'The namespace', 'The attribute name', 'the namespace', 'The namespace name', 'The element', 'The element name', 'The name of the namespace', 'The namespace<mask1>', 'The name of the element']不常见的缩写，会被匹配成更常见的全称，如这里的namespace，但是对应缩写应该是nmse才对。
- attrUri => The Namespace URI of the attribute ✅
['attribute URI', 'attribute uri', 'The namespace URI', '@return true if successful', '@param attrLocalName\n@param attrValue\n@param elem', 'The URI of the attribute<mask1>Handler', '@param attrLocalName\n@param attrRawName', '@param attrLocalName\n@param attrRawName\n@param attrValue\n@param elem', 'The URI of the attribute<mask1>String', '@param attrLocalName\n@param attrValue']因为没能生成注释，所以补充时把attrUri后面的参数注释补上了 => 第一步的注释生成效果不佳会导致第二步的补齐出现问题。
为什么生成结果里也带掩码，<mask1>？
- iae => IllegalAccessException ❎
