After graduation, the first contact testing job was in a small communication company. Most of the work I contacted was mainly functional testing. The salary has always been several thousand yuan, and I was once sent out Poor, and part-time various products, operation and maintenance, and operation work, I don't feel like a tester. Seeking stability, I have been "mixing" like this for 2 years. I don't want to fall like this, I want to keep improving myself.
Before joining this company, that is, two years ago, I started to plan my own life, so in the two years, I did not slack off.
Now, I have switched to Ali and successfully won the offer. My own situation is very ordinary, with a bachelor’s degree and no background. I want to share my experience this time, and I want to encourage people who have the same starting point as me!
Everyone has a dream of a big factory. For programmers, the first-line Internet companies headed by BAT must be their favorite objects. After all, they can work in these big factories, not only with high salary and good treatment, but also with the ability to improve technology. The key is to be able to coat yourself with a layer of gold, so that people can look up to you.
However, some people are unemployed and others are employed. Dachang’s core track is not always recruiting people. The key is how to enter the core track—to improve self-core value and possess irreplaceable ability! !

First things first: clear the stages and make a plan
Since my university, I have become clear about my current situation, and I also understand that if I want to change my life, I must know how to plan. Therefore, since my internship, I have already made a plan for my career, and my plan is clearly divided into several stages, and the goals and focus of each stage are also established.
- The first stage: 0~3 years; the first time I gave myself was 3 years, 3 years to complete the first job hopping, and I need to jump to a larger platform.
- The second stage: 3~7 years; establish your own development direction, automation test engineer, test development, performance test or security test can be used, but I know that no matter which direction it develops, the reserve of technical knowledge must be systematic and perfect.
- The third stage: 7~future; at this stage, I should have completed my own development direction. At this time, I need to think about life, or continue my hobbies, enjoy life, or start a business.
The second thing: sort out knowledge and re-learn
During the three years at Vipshop, I prepared for job-hopping and for the development direction of the second stage, so I sorted out my knowledge and let myself start learning again. In the past three years, I have never failed to improve myself, and my learning direction is also carried out according to the knowledge route I have sorted out, step by step and methodical.
Phase 1 Test Basics
The basics of testing are the most important part of software testing. As long as you are doing testing, no matter what kind of testing it is, you must learn the basics and theoretical knowledge of testing. What is the best level of learning? It is best to be able to understand and express in your own words. After all, during the initial test of the interview, the questions asked are all assessed from the basic theory. What is the basis of the test? The definition of test, the classification of test, the method of test, the life cycle of test. Writing of test plans, test scenarios, test strategies, and test cases. The classification of BUG, the six elements of BUG, the life cycle of BUG, the definition of BUG, the relationship between testing and development processes, waterfall flow, V-shape, W-shape (double V), spiral, agile, etc. Analysis and management methods such as PDCA and 5W2H Quality Management System CMMI (Understanding) Well, probably the above content, all of the above are theoretical and document capabilities, as long as you are willing to memorize and write, you can master them independently.
The second stage of tool learning
After learning the basics of software testing, it's time to learn the tools. In fact, learning tools is really easy, so you don't have to worry about the choice of tools. Just learn the most basic tools, and learn whatever tools you use in the future. At this stage, the focus of learning tools is on the learning of interface testing. The learning of all tools is to pave the way for the learning of interface testing. Below I will list the tools and knowledge points that need to be learned, just learn them in order. Simple network protocols: TCP/UDP, HTTP/HTTPS Basic operations and common instructions of Linux. Basic operation of MySQL database and common SQL statements. The use of fiddle capture tool. The use of postman interface testing tools. The use of jmeter and loadrunner performance testing tools.
The third stage of code learning
OK, after learning the above two parts, congratulations, you are already an excellent junior test engineer. Next, you have to consider the direction of your development. Is it to become an automation test engineer? Or a performance test engineer? Or a security test engineer? ah! This question is so difficult! I don't know how to choose. Anyway, I know a little bit about everything, and I can meet for any position. Regarding the choice of direction, see this article of mine. Well, I believe you already have the answer in your heart, then let's continue to talk about it below. At this stage, we should learn code. Regarding the choice of programming language, I recommend python. There is also a database that must be mastered! In the study of tools, I think you can already master the related applications of the database! So now you can learn programming languages, but you don't have to learn as deeply as development . Such as Java. The same is true for python (python has become mainstream now) In short, you can choose one of the two to learn in the early stage. The suggestion is to learn python? You ask me what I learned. Of course I can do both. Hahahahahahaha, surprise! Not surprisingly!
The third thing: keep blogging and take more notes
Qualified developers must develop good study and work habits. Why should programmers write blogs frequently and take more notes? The reason is simple:
Organize thinking and strengthen understanding. It is convenient for future review and review. Record growth. Practice writing organization skills. Feedback and interact with other people, others will find some problems that you can't find, and improve your thinking.
The fourth thing: community interaction, broaden the circle
I believe that every working social animal knows the importance of personal connections, and we developers also need to accumulate our own personal connections. Therefore, during the three years at Vipshop, I did not just go out early and return late, and work in front of the computer all day long. I would use my remaining time to participate in some communities, communicate with peers, and participate in offline activities. Meetings or events are a more direct way for me to broaden my circle.
The fifth thing: Know how to review and prepare for interviews
I learned to review myself and give myself a summary every year, including knowledge, work, life and emotions, whether I have further improved my richness. This year is the end of the third year of my first phase, and I will also make a summary of the past three years for myself. At the same time, I will also start my job-hopping plan and prepare for interviews.
As the saying goes, stones from other mountains can be used to make jade, and it is helpful to read more and learn from them. After finishing these, 20k+ is ready!

2. Interview strategy
A summary of my interviews this year:
No matter what level of test engineer you are interviewing, the interviewer will ask "Can you program? Do you have experience in automated testing?"
In the final analysis, the software testing industry is still a technical position. With the continuous influx of personnel changing careers and graduating college students into the software testing industry, the ceiling of the industry is gradually rising. It is becoming more and more difficult for testers who are only a little Based on the industry, it will gradually be replaced by automated test engineers and test development engineers.
I was in a bad mood at first, but what my friend said broke me. In the final analysis, my technology is still not enough, and I only know some basics of automated testing, so I will be easily eliminated or replaced: due to the large inflow of these unqualified products in the market Most companies have to lower their expectations because they consider themselves excellent testers, but the truly capable testers are basically not affected, and it is still easy to change jobs. If you are dissatisfied with your current job and do not have enough experience, you may wish to calm down and study further.
