4.1 自定义多线程执行jest测试脚本

jest本身就是多进程执行文件，本次只是在学习工作线程的一次尝试

1、准备两个测试文件

test.js

const assert = require('assert')
describe('test',function (){
    it('should ', function () {
        assert.ok('1')
    });
})

hello.test.js

const assert = require('assert')
describe('',function (){
    it('should ', function () {
        assert.ok('1')
    });
})

2、main.js

//工作线程的代码都在其他文件里，所以不用判断isMainTread
const { Worker } = require("worker_threads");

// if(isMainThread){

    let  worker1 = new Worker(`${__dirname}/worker1.js`);
    let  worker2 = new Worker(`${__dirname}/worker2.js`);
    worker1.on('message',function (msg){
        console.log(msg+'111')
    })
    worker2.on('message',function (msg){
        console.log(msg+'222')
    })
// }

3、worker1.js

var process = require('child_process');

var cmd = 'jest /src/check_file/hello.test.js';
process.exec(cmd, function(error, stdout, stderr) {
    console.log("stdout:"+stdout);
});

4、worker2.js

var process = require('child_process');

var cmd = 'jest /src/check_file/test.js';
process.exec(cmd, function(error, stdout, stderr) {
    console.log("stdout:"+stdout);
});

5、执行main.js代码后，test.js/hello.test.js会以两个线程执行，生成的测试报告，也会分成两份
