toBeCalledWith 和 toHaveBeenCalledWith 之间的玩笑区别

Question

这在文档中并不明显，但是...toBeCalledWith和之间有什么区别toHaveBeenCalledWith？

Answer 1

从文档https://jestjs.io/docs/en/expect#tohavebeenCalledwitharg1-arg2-

.toHaveBeenCalledWith(arg1, arg2, ...) 在别名下： .toBeCalledWith()

从源代码：

https://github.com/facebook/jest/blob/b7cb5221bb06b6fe63c1a5e725ddbc1aaa82d306/packages/expect/src/spyMatchers.ts#L1128

https://github.com/facebook/jest/blob/b7cb5221bb06b6fe63c1a5e725ddbc1aaa82d306/packages/expect/src/spyMatchers.ts#L1131

//...
  toBeCalledWith: createToBeCalledWithMatcher('toBeCalledWith'),
  toHaveBeenCalled: createToBeCalledMatcher('toHaveBeenCalled'),
  toHaveBeenCalledTimes: createToBeCalledTimesMatcher('toHaveBeenCalledTimes'),
  toHaveBeenCalledWith: createToBeCalledWithMatcher('toHaveBeenCalledWith'),
//...

它们是由createToBeCalledWithMatcher具有不同名称的函数创建的。

所以，他们是一样的。
