tracker.report()

• 返回：包含关于 tracker.calls() 返回的封装函数信息的对象 <Array>。
• 对象 <Object>
  • message <string>
  • actual <number> 函数实际调用次数。
  • expected <number> 函数预期调用次数。
  • operator <string> 被封装的函数名称。
  • stack <Object> 函数的堆栈跟踪。

这些数组包含了有关未按预期次数被调用的函数的预期和实际调用次数的信息。

【The arrays contains information about the expected and actual number of calls of the functions that have not been called the expected number of times.】

// Creates call tracker.

// Returns a function that wraps func() that must be called exact times
// before tracker.verify().

// Returns an array containing information on callsfunc()
