testing - 函数调用是否缺少参数语义或语法错误？

Question

我收到一条评论，说调用参数数量不正确的函数是语义错误。我会说它是一个语法错误，因为正确的语法是使用分隔符提供尽可能多的参数。

还有一个问题：如果程序员没有正确理解需求并实现了与请求不同的功能，那是逻辑错误吗？它是否被认为是一个错误？

Answer 1

A syntax error has to do only with conformance to the language.

A semantic error has to do with conformance to the API.

A function call that has the wrong number of parameters for the defined function is a semantic error.

As to your second question, at least by my definition, a logic error is when the code compiles and runs but does not function as expected, so I would call your example a logic error. But I'm not sure this definition is universally accepted or obvious, so it may be a matter of opinion.

Answer 2

方法调用的参数数量不正确是语法错误。如果程序不这样做，客户期望也是一个错误。请求阶段的错误被触发到代码阶段。
