source of involution
The earliest "source" of the introversion is a few pictures of top students from famous schools.
Some of the "inward scrolling" pictures of college students blowing up their circle of friends are as follows: Some people are reading books on bicycles, some people have stacks of books on their dormitory beds, and some people even read books while riding bicycles. Writing papers on a computer. These pictures were first circulated among the academic masters of Tsinghua University and Peking University. Afterwards, popular words such as "watching the computer while riding a bicycle" and "Tsinghua Juan Wang" appeared on the hot search, and related emoticons also appeared on the social software of many college students. So this is also the reason why the current graduating students 00 back door is excellent! ! ! But when I get older, I really can’t bear the toss. I can’t go to bed late and get up early, and I can’t hold my mobile phone after dinner and get off work. I just want to take a comfortable bath and sleep after work.
Why does involution exist in the testing circle?
As the IT Internet boom intensifies, a large number of fresh graduates choose to enter the IT circle after graduation, and another group of migrant workers switch to the IT industry for high salaries and benefits. More and more people are pouring into the army of programmers. Coupled with the popularity of the Internet industry, a large number of programmer positions have been created, and the threshold is getting lower and lower than before. Especially with the framework and toolization of programming, the requirements for programmers are not so high. Programming technology is no longer difficult to reach, and the barriers to entry are no longer unattainable. The lowering of the threshold means to us that more and more newcomers are pouring in. If you do not have a breakthrough in technology, then you will inevitably fall into a highly introverted situation.
Therefore, many junior and middle-level test engineers are looking for breakthroughs, hoping to break through to the senior or even architectural level, and become a scarce talent in the market; or hope to enter a large factory, receive more formal and systematic vocational training, and handle a larger scale. More complex projects, access to more and better colleagues and partners.
But this is not an easy task. There is no professional curriculum system for testing. When many test engineers learn, they learn a little here and a little there. It is not particularly systematic, which leads to their weak technical foundation. They don’t know what they want. In addition, they are surrounded by a growth environment that is far inferior to that of a big factory. If they want to continue to grow and break through difficulties on their own, it is like finding a way in the fog. There are many difficulties and it is easy to give up halfway.
Only by constantly improving yourself can you stand out in the harsh environment of involution
I think everyone knows the status quo of their careers. If you can’t change your career, you can only find ways to change yourself. Self-examination, continuous learning, good planning, based on 10-20 years of career, plan ahead. Don't wait until you are 40 and still submit resumes for interviews everywhere, and wait for the rice to cook at home, that would be too passive.
In order to help programmer friends change jobs for interviews, get promoted and raise their salaries, face career difficulties, and improve their skills, this article provides you with a set of quick learning methods and notes covering testing all technology stacks. At present, I have received feedback from seven or eight netizens, saying that the interview asked a lot of knowledge points.
The content involves: testing theory, Linux foundation, MySQL foundation, Web testing, interface testing, App testing, management tools, Python foundation, Selenium related, performance testing, LordRunner related, etc.
