The first thing to say is that the industry has been changing in the past two years. The main trends in the industry are as follows:
1. It seems to be "declining" on the surface, but it is rapidly iterating internally;
2. Personnel are polarized, only manual absorption into outsourcing, the basic requirement of the industry is to know performance and automation, and then develop towards testing and development;
3. The threshold for entering software testing is increasing, technical threshold and academic threshold;
4. More research and development into the field of testing;
5. The salary of test engineers is constantly increasing.
Tell me how to light up your "skill tree" as a test engineer:
As a qualified test engineer, you need to have the following skills:
· Test basic theory/test design ability
· Business knowledge
· Industry technical knowledge
· Database
· Master the programming language
Get automated testing done
· Quality process management
Test basic theory/test design ability
For example, boundary value analysis, equivalence class division, causality diagram, decision table, orthogonal experimental design, etc. These basic test foundations and scientific design methods can well regulate our behavior, thus helping us to clarify our thoughts and ideas. Improve efficiency. Many people think that the answer is short, thus ignoring the solidity of the foundation. Often the most basic place is the most difficult to master.
business knowledge
This seems very imaginary, and it seems that there is no specific knowledge point, but anyone who has done the test knows that this part is often very important. If you don't understand business knowledge, it is reckless and blind. As a tester, the most important thing is to think about problems from the user's point of view, not the development side, find the core business and functions, and then divide the test priority and classify the defects. In addition, it is also very important for automation. For example, only when you have mastered the characteristics of the business, can you use automated means to cover which scenarios first, and invest valuable automation resources in the most important places.
Industry technical knowledge
When it comes to industry knowledge, it's gone. It’s not that we know a little about testing methods, we can run a script, and we’re done using a framework, or that the testing requirements cover a wide range of areas, and you have to be proficient. For example, the front-end technology stack, API design, back-end server, database, service architecture, etc., if these knowledge can be opened up, during the interview, if the interviewer asks you a question, you can explain it point by point, reflecting your Definitely a good test engineer.
database
Whether you are doing automated or manual testing, you must perform data validation. SQL language is one of the skills that test engineers must have. Mastering SQL language and then finding the required data in the database is a must.
master programming language
Test without writing code? That's not called a test engineer. Especially for test development, it is necessary to start quality control from the code layer, so if you master the language, you can understand the code, locate defects directly, and estimate risks and difficulties earlier. Another aspect is automated testing, to control the development of various automated testing frameworks and use cases.
Get automated testing done
For UI automation, it is very important to master selenium and appium, especially appium on the mobile side. Enterprises pay more attention to it. The basic idea is to locate elements, then operate elements, then obtain feedback, and finally use the test framework to manage tests use case .
In addition, interface automation has many unique advantages over UI automation in terms of input-output ratio, such as high operating speed, low development and maintenance costs, and it can be developed simultaneously with the development code. To put it simply, by simulating a browser , sending a request to implement an interface call, comparing the return value with the expected value, and verifying the result.
Quality Process Management
The last thing to talk about is quality management . For testers, it is not just to do testing, but to be responsible for the quality assurance of the business.
As a key role in DevOps, future software test engineers and quality personnel must have certain development and operation and maintenance capabilities;
· Testers will get more deeply involved in the development work. By "shifting testing to the left", they will work with developers to formulate test plans in advance, and promote code review, code audit, unit testing , automated smoke testing, test precision analysis, and R&D self-testing, etc. To ensure the quality of the research and development stage;
· In addition, testers will also participate in configuration deployment, configure automated test cases into the continuous delivery chain, and monitor the application quality after release through the whole process through "shifting testing to the right".
