For many people who are new to the industry or planning to enter the industry and become software testing engineers, they just started to contact this industry and don’t know what they should learn, or what knowledge they must master to become a qualified testing engineer.
According to the author's opinion, if you can learn the following knowledge points well during the learning process and build a good testing knowledge system by yourself, then it will be very easy to enter the industry~
01 Learn the basic theories of testing well
It is said that theoretical knowledge is the cornerstone of learning. For software testing learning, learning the basics of testing knowledge is also very important.
First of all, we need to master the software testing development process and related models, understand the relevant knowledge of agile development, be able to classify tests, master the testing process, and be able to write test cases (including but not limited to use case design for black box testing, etc.);
Then, learn defect (bug) management and software life cycle, and be able to write test reports, etc.;
Next, learn about the test points and test methods of different ports, such as web pages, mobile phones, etc. At this stage, we usually need to learn the system, compatibility testing, special testing, interface testing, performance testing, and learn to use tools. Common ones include Monkey and so on.
Finally, you must be able to write common test documents, such as bug tickets, test plans, software test reports, etc.
02 Learning database
We all know that the reason why software can realize the interaction between the front end and the back end is mainly due to the connection between data. No matter what type of test it is, it is inseparable from the use and support of the database. The interaction between the front and back ends of the software is essentially data interaction. Therefore, it is very important to learn to use databases.
Regarding databases, novice testers need to understand the basic concepts of databases, relational databases, database SQL additions, deletions, modifications, common table operation statements, and the use of database tools. For example, the use of Navicat and so on.
03 Learn to use Linux system
We all know that Linux system is the main server operating system. In daily work, if we want to locate the source of some bugs, we need to check the server-side logs. Many times, it is not practical to check the logs directly on the software testing server. Therefore, we need to build a testing environment through the Linux system and use the server of this testing environment to find bugs.
Therefore, as test engineers, we need to master the basic knowledge points of Linux, such as multi-user, multi-version, multi-release and other related knowledge; we also need to know common Linux commands and tools, be able to deploy and configure basic applications, and be able to install and use them. docker, can write basic shell scripts, use remote terminal tools, etc.
04 Can do interface testing
We mentioned earlier that we need to learn the basic knowledge of interface testing, but here we focus more on practical operations. Regarding the interface testing part, we mainly divide it into several parts: including HTTP/HTTPS protocols, common request methods, cookies and sessions, interface documents and test cases, the use of interface testing tools, etc.
We all know that interface testing is essentially a type of functional testing, but interface testing is extremely important because it connects various systems of the software. Therefore, it is very important to learn interface testing well. By doing interface testing well, hidden problems in the software can be discovered earlier, thereby improving testing efficiency and reducing repair costs.
05 Can do performance testing
Regarding performance testing, the author believes that it is a testing section with relatively high technical requirements. If you are new to the industry, you can consider performance testing as a goal after two years of work. But before that, you must first master the relevant content of performance testing, so that you can slowly establish a foothold in this field.
Therefore, we need to learn the basic concepts of performance testing, testing processes (including but not limited to demand analysis, scenario design, script writing, performance tuning, etc.), use performance testing tools (such as Jmeter, Loudrunner, etc.), and write performance test reports . In addition, getting more exposure to performance-related projects and learning complete project experience will be very helpful for our future development.
06 Master automated testing
Automated testing is a popular testing method nowadays and is also a direction for the future development of the testing industry. Learning automated testing is a step towards getting a high salary for novices. Therefore, before that, it is particularly important to master one or several programming languages.
Personally, I recommend Python first, followed by Java, and you also need to master certain front-end knowledge. In addition, you must master the relevant automated testing tools selenium, appium, etc., and of course, master the commonly used automated testing frameworks. For interface automation testing, if it is implemented in python, you need to master the use of requests library and unittest framework.
07 Others
Friends who have the spare capacity can also master some public knowledge, such as the use of SVN, Git version control, the deployment and use of continuous integration Jenkins, etc.
This part is mainly to help us better handle and complete some of the more distinctive test problems in our work. Although these techniques are not used frequently, when they are used, there may be problems of not knowing what to do. So friends who have spare energy can learn more.
write at the end
In fact, what I mainly introduce to you today is a framework. If you friends can see this, I would like to express my deep gratitude. The album page at the end of the article is the author’s test knowledge sharing under long-term coding. Interested friends may wish to click on the album page to see if there is any knowledge that interests them.
It is said that there is a road to the mountain of books, and hard work is the path to it, and the sea of learning is boundless and the boat is made of hard work. Reading one more book and learning one technical point can bring us one step closer to a better version of ourselves.

Software Testing Interview Document
We must study to find a high-paying job. The following interview questions are from the latest interview materials from first-tier Internet companies such as Alibaba, Tencent, Byte, etc., and some Byte bosses have given authoritative answers. After finishing this set I believe everyone can find a satisfactory job based on the interview information.
