Node.js new assert.CallTracker()用法及代码示例

new assert.CallTracker()

创建一个新的 CallTracker 对象，该对象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') 处理程序中调用它。

import assert from 'node:assert';
import process from 'node:process';

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();
});const assert = require('node: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();
});
