tracker.report()

• 返回: <Array> 包含有关 tracker.calls() 返回的封装函数的信息的对象的数组。
• 对象 <Object>
  • message <string>
  • actual <number> 函数被调用的实际次数。
  • expected <number> 函数预期被调用的次数。
  • operator <string> 被封装的函数的名称。
  • stack <Object> 函数的堆栈跟踪。

数组包含有关未调用预期次数的函数的预期和实际调用次数的信息。

import assert from 'node:assert';

// 创建调用跟踪器。
const tracker = new assert.CallTracker();

function func() {}

function foo() {}

// 返回封装 func() 的函数，其必须在 tracker.verify() 之前调用准确次数。
const callsfunc = tracker.calls(func, 2);

// 返回包含 callfunc() 信息的数组()
tracker.report();
// [
//  {
//    message: 'Expected the func function to be executed 2 time(s) but was
//    executed 0 time(s).',
//    actual: 0,
//    expected: 2,
//    operator: 'func',
//    stack: stack trace
//  }

• Returns: <Array> of objects containing information about the wrapper functions returned by tracker.calls().
• Object <Object>
  • message <string>
  • actual <number> The actual number of times the function was called.
  • expected <number> The number of times the function was expected to be called.
  • operator <string> The name of the function that is wrapped.
  • stack <Object> A stack trace of the function.

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.
