You need to know why the company wants to recruit beta , First of all, understand 【 Test Development 】 What do they do .

The work content of test development can be roughly divided into the following three types ：

1. Only develop , Don't test
2. Develop and test
3. Only test , No development

「“ Only develop , Don't test ”」

Some big Internet companies have developed to a certain scale , The user volume is very large , At this time, if there is a bug, There's always a huge butterfly effect , Bring huge loss to users .

Conventional Manual testing

It has been unable to meet the needs of daily testing , It's up to the baseman alone to ensure the quality of the business , The test is one-sided 、 It costs a lot 、 Low efficiency .

So big factories don't hesitate to hire test and development engineers at high salaries , Develop test tools or platforms to , Rich testing methods , Improve test performance , Strengthen product quality , Ensure high availability of the system .

「“ Develop and test ”」

Some medium-sized Internet companies , Business is on the rise , But quality engineering is still in its infancy .

Recruited at this time Test Development Engineer

, Need test development to lead a number of outsourcing students to ensure the business test tasks , And then you need to start from 0 To 1（ Or from 1 To n） Go ahead quality

Infrastructure is built .

Be both a father and a mother , It's a lot of work , Basically, the vast majority of test development engineers are in this stage .

「“ Only test , No development ”」

“ Interview to build rocket , Working screw ”, It's quite appropriate to use it here .

Generally, some companies have many and complicated businesses , We need to recruit someone with a little stronger ability Business test

Little expert go Cover Quality assurance work .

Although these companies are recruiting test and development engineers , But when it comes in , In fact, it's just business testing .

  Compared with the above two types of test development ,“ Only test , No development ” Test and development engineers are still in the minority , And working “ happiness ” Generally not high .

But anyway ,「 Recruitment “ Test Development Engineer ” The threshold stone is still better than “ Test Engineer ” Higher , Wages will also be relatively higher .」
