new assert.CallTracker()

创建新的 CallTracker 对象，其可用于跟踪函数是否被调用了特定次数。 必须调用 tracker.verify() 才能进行验证。 通常的模式是在 process.on('exit') 句柄中调用。

const assert = require('assert');

const tracker = new assert.CallTracker();

function func() {}

// callfunc() 必须在 tracker.verify() 之前恰好被调用 1 次。
const callsfunc = tracker.calls(func, 1);

callsfunc();

// 调用 tracker.verify() 并验证是否所有 tracker.calls() 函数都已被准确调用。
process.on('exit', () => {
  tracker.verify();
});

Creates a new CallTracker object which can be used to track if functions were called a specific number of times. The tracker.verify() must be called for the verification to take place. The usual pattern would be to call it in a process.on('exit') handler.

const assert = require('assert');

const tracker = new assert.CallTracker();

function func() {}

// callsfunc() must be called exactly 1 time before tracker.verify().
const callsfunc = tracker.calls(func, 1);

callsfunc();

// Calls tracker.verify() and verifies if all tracker.calls() functions have
// been called exact times.
process.on('exit', () => {
  tracker.verify();
});
