After coding for so many years, what is your annual salary?
I, 4 years old, had the highest salary of 16k*12, and the annual salary was less than 20W. It is said that the salary in the IT industry is high, but there are still very few people at the top of the pyramid with an annual salary of one million. People like me are the ordinary majority, but they still have to work overtime in exchange for a lot of psychological pressure. They often code for two weeks in a row. No time to rest either.
I work in a traditional industry, and the welfare is far inferior to that of an Internet company. I have been thinking about it for a long time and want to enter a big Internet company, but I really can't compete with the 985 and Sea Turtle Elites who get together.
But the obsession is too deep, I always feel that Internet companies are my destination, and I even took a "detour" in order to enter an Internet company.
Tian Ji has heard about horse racing since childhood. This time, I used it in career planning. I gave up 4 years of development experience and changed the track to test.
The mediocre code in the usual work is actually brilliant in the testing position. With the foundation of development, I have a deeper understanding of the software's internal implementation, functional requirements, and functional implementation. I can analyze based on my own experience, where errors are prone to occur, and quickly locate them. It is more targeted to find out where the bug occurs.
During the entire learning process, tens of thousands of lines of code were written, and I was exposed to many advanced framework ideas: PO model, data-driven, keyword-driven, parameterization, continuous integration...
Through the encapsulation and optimization of the code, the encapsulation of the interface, web, and app automation framework is completed. These three sets of frameworks with high reusability and scalability can be directly applied to interviews and work...
After the training course, the salary of my testing position has already surpassed the salary in the heyday of development - 19k*16 salary, and the annual salary has finally passed the threshold of 30W. Tube lunch.
10 to 6 plus weekends is something I never thought about when I was doing development.
Choice is greater than hard work. Sometimes what you want desperately, maybe you can easily get it by changing the direction.
Advantages of developing to testing
1. The requirement for development is depth, and the requirement for testing is breadth. Testing can make your knowledge more extensive;
2. Familiar with Linux system, familiar with SQL, very helpful for software testing, and more competent for software testing;
3. Have a deeper understanding of the internal implementation, functional requirements, and functional realization of the software, and be able to analyze based on your own experience, where errors are prone to occur, and quickly locate and find out where the bugs appear, which is more targeted;
4. Understand development, be good at communicating from the dual perspectives of development and testing, and improve efficiency;
5. Strong logical thinking ability, good at coding, more suitable for automated testing, higher average salary.
Compared with development, software testing requires slightly lower academic qualifications, and the card is not so strict, but its development prospects are not lower than development.
As long as the technology is in place, there are many people with an annual salary of 30W for 2 years of age measurement. Especially for those in the IT industry who transfer to the test, the experience of being a code farmer can also be a plus point for your interview~
Once you have clarified the specific advancement route, then give yourself half a year to a year, hold your breath, and work hard in this direction!
Why learn test development?
When you still feel:
The overall environment is sluggish, and I have no competitive advantage, so I tremble when it comes to layoffs;
There will be career development bottlenecks in the testing industry, salary will be limited, and will not be taken seriously;
Daily repetitive work breeds confusion and no sense of accomplishment
You might as well go to the major recruitment platforms to see the recruitment requirements of software test development engineers (SDET). This is a position that the first-tier Internet companies (BAT, TMD) pay a lot of money to hire, and it is a position that will be hard to find!
Test development engineer, who can test and develop, can provide test technology solutions from the perspective of a test architect with the help of good development capabilities
Develop and implement testing tools or platforms to assist the company's internal test engineers to better complete the test work and complete project delivery faster, serving to improve the efficiency of test execution and internal quality processes.
With the application of DevOps and continuous delivery concepts in major enterprises, traditional functional testers have become a shortcoming of enterprises
A test development engineer who is proficient in development and testing can guarantee the quality of the written software, invisibly save a lot of costs for the enterprise, and improve the efficiency of the test team. This is what modern agile development teams are pursuing!
It is understood that there is currently a gap of 200,000+ in the testing and development of senior talents in the testing and development of major networking manufacturers, which has become a "sweet pastry" for major manufacturers to bid!
A picture clearly shows the difference between an automated test engineer and a test development engineer:
How to move towards test development, is there any reliable way?
As an old tester for almost ten years, I have a deep understanding of the difficulties in the learning process. So I am keen to collect and organize resources, and record the process from stepping on the pit to climbing the pit. I hope that I can record what I have learned, the techniques used in actual work, self-study methods, experience , and some pitfalls I have stepped on.
I also hope that you, who want to learn by yourself, can avoid some detours through my sharing, and can form your own system and apply it to practice. Of course, I sincerely hope that you will get promoted and raise your salary. Perhaps this is the most practical thing.
