As a senior soft tester who has worked for 10 years, I would like to share with you what courses you need to learn in software testing. First of all, if you want to engage in the software testing industry, you need to have the following conditions: enough care, patience and responsibility; Have a certain foundation of software testing, the so-called high-rise building starts from the ground, and it is the key that everything is difficult at the beginning. Don't listen to others say that testing is easy, just because you really think it's easy to get into the testing industry by mistake. I can only tell you that your friends may be superficial and will give you the wrong guidance. With the development of the Internet, the demand for talents is increasing day by day, and the requirements for testers are getting higher and higher. What are the requirements of enterprises for testers now? We mainly explain it from the following aspects.
First: Have a certain functional testing foundation and computer foundation.
Why do software testers need to have a certain software testing foundation? Because if you don't know what software is. What is software testing? How do you test the software? Software testing is based on software testing, so we give priority to understanding what is software and its classification and composition, and what is software? Software = program+document+data. Software is divided into system software and application software. System software refers to windows operating system and Android operating system. Application software includes: Taobao Mall, Today Headlines, etc. The content of application software belongs to the basic part of computer and needs to be mastered. After we have a certain computer foundation, it is relatively simple to learn the basic knowledge of software testing. What does the software testing foundation include? First of all, we need to understand the characteristics of software testing. According to the test characteristics, it is divided into different development stages, and different test models are derived from different stages, such as waterfall model and V model. Based on different model processes, it is divided into software development process and software testing process. Let's briefly explain the V mode first. After all the development processes, such as the development process on the left, the test process on the right and the characteristics of V model, are developed, the test work will lead to high rework cost. So V mode has some shortcomings, so other modes are born. Since we mainly study software testing, we will focus on the testing process. The correct testing stage of V model includes four stages: unit testing, integration testing, system testing and verification testing. Combined with the software testing process, this paper analyzes the basic knowledge of software testing that we need to learn. First of all, the test process includes the following stages: requirements analysis-test plan-use case design-test environment construction-test execution-defect management-test report. Based on the different test types, it can be divided into white box test, black box test and grey box test. The above content is based on the knowledge points that must be mastered in the basic stage of software testing. Please pay attention.
Second: Know at least one programming language, such as Python and java.
Why do testers need to learn programming? Part of our software is made up of programs. Do programmers make mistakes when writing programs? That's for sure. A program error means an error. How did the bug come about? If you can understand the program, you can directly analyze the problem by reading the program, which is conducive to better positioning. This is part of the positioning white box test. The ultimate goal of learning programming is to provide help and support for testing and development. All testing tools are code-based, and it is relatively easy to test with a certain code foundation. After all, what is needed in the market at present is a full-stack test engineer, so please be sure to master a programming language.
Third: Have a certain understanding of computer networks.
Why do you need to learn network knowledge to do the test? The web system and app application that we usually contact are actually communicated through the network. Based on the OSI seven-layer model, the first layer is that the network layer mainly connects with the server through IP address and port number, and the performance test layer also needs to analyze the bandwidth speed of the network to test.
Fourth: Skillfully use windows and Linux operating systems and understand the working principle of operating systems.
All our software is installed and deployed based on the operating system, including performance testing. In fact, the performance monitoring of operating system applications, the construction of project test environment and other related contents are all based on the operating system, so we should focus on the principle of operating system.
Fifth, master a database language and skillfully operate SQL statements.
As we all know, we usually visit websites based on interfaces, and we usually add, delete and check interface data. After all the data is modified, it is transmitted to the server through the interface, and then reaches the data service, and the data is stored in the table of the database. We need to check whether the data can be stored in the data correctly. At this time, it needs to be applied to basic SQL query statements, so you must master the application of SQL skillfully.
Sixth: Have experience in automated test development, master test tools, master front-end H5 and JS related knowledge, and use test tools to complete daily automated test work.
Learning automatic testing tools is mainly to share the workload for manual testing, improve testing efficiency and improve the happiness of testers. Therefore, we must master the most common testing tools in the market and some knowledge of element positioning related to front-end H5 and JS. The core content that automatic testers must master.
Seventh: Have working experience in performance testing and interface testing, and will use performance testing tools and interface testing tools for testing.
The first application of performance testing tools is something that performance testing engineers must master. Why should they learn the basics of interface testing? Because the performance test is a multi-thread test based on the protocol.
Eighth: Have certain communication skills and document writing skills.
As a qualified tester, communication and expression skills are very important. Sometimes, the company needs to do some project demonstration. Testers need to organize meetings, including communication among internal employees, to make communication problems between departments smoother. Generally speaking, testing and writing test case documents, defect analysis summary reports, test reports, user manuals and other related work require document writing skills, so it is necessary to be an excellent tester.
Summary: Through the above description, we have a clear goal of what knowledge the software testing major needs to learn, and hope to help you through detailed answers.
Asking these questions, you should be Xiaobai. First of all, it is certain that the domestic software testing work is relatively simple and easy compared with the development work of Java and C. Of course, this is only the initial stage.
Probably divided into functional testing, automation testing, interface testing, performance testing, different employment directions determine your study courses, as well as some databases and testing tools, not to mention examples, there are many online. Even if you know what courses there are, it's just a patchwork.
What I can give you is to find a course outline and have a brief understanding of whether it suits you. It doesn't matter if you can't find it. Just find a training institution, such as Beijing Zhonggongyou Employment, and sign up for a seven-day free audition course. You will know whether you are suitable to learn this in a week.
Finally, it's up to you to choose whether to report to class directly or to study by yourself.
The relatively high salary in the IT industry is very attractive to most small partners, and relatively simple software testing is also deeply loved by the public. Many young people want to engage in software testing, but what skills do they need to learn to do software testing in the IT industry? Let's get to know each other! To learn software testing, we must first start with the basic testing theory, and master what works in the software life cycle and how to test, including the work content. Then you need to know the basic programming knowledge you need to master, such as HTML and JavaScript in the front end, Java and c/c++ in the back end, and you need to know one or several of them. Another very important basic part of learning software testing is database learning. For example, the mainstream database management systems in the industry now include Oracle, MySQL and SQLServer. At least one of them should be mastered, and the basic principle, technology and operation of the database should be understood. Besides being familiar with windows system, you must also be familiar with Linux, Unix and other systems, and master the use of these operating systems and the construction of test environment. After having the above basic knowledge, you need to continue to learn the professional knowledge related to software testing and understand some automated testing tools, such as QTP and LoadRunner. , and master the basic theory and testing methods of mobile phone testing, master the use of common mobile phone testing tools, and lay a solid foundation for mobile Internet testing. Knowing this, I have a general understanding of the foundation of software testing. Is the direction of learning software testing more clear? If you want to enroll in software testing classes, or are interested in software testing, you can consult the in-service teachers of Zhonggongyou for details. The software testing training course with excellent employment is relatively good in the industry. Excellent employment has a strong teaching team, systematic and comprehensive curriculum structure and guaranteed employment service. After learning the software test, you don't have to worry about finding a job.
