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。

const assert = require('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.

const assert = require('assert');

// Creates call tracker.
const tracker = new assert.CallTracker();

function func() {}

function foo() {}

// Returns a function that wraps func() that must be called exact times
// before tracker.verify().
const callsfunc = tracker.calls(func, 2);

// Returns an array containing information on callsfunc()
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
//  }
// ]
