First, work actively.

Work attitude is the most important aspect to evaluate a tester. If a high-level tester (pure technical ability) doesn't have a good working attitude, sometimes he can't promote the testing work in the testing team, and sometimes he can hinder it. And a willing tester, even if his technical level is not high and he is not smart, is serious and responsible for his work. He can do whatever you ask him to do. This is also one of the main reasons why many enterprises are willing to let people who have just joined the work do the testing work. In addition, whether testers are active in their work will also greatly affect the development of a tester. For example, one of my testers will teach himself QTP in his spare time to improve his technical level, so that in the next test, he can skillfully use this testing tool for automated testing, which not only improves work efficiency and reduces work intensity, but also creates better development opportunities for himself (because QTP works well, he was promoted to be the test leader). Therefore, it is very important for a person's development to make effective use of working time and take the initiative to study. Another example is similar. Another tester of mine volunteered to participate in the testing work of other groups, regardless of his technical level, when his testing task was abnormally terminated and the tasks of other test groups were very busy. This attitude of asking for a job made him stand out and caught my attention. Naturally, he will pay special attention to his work, and he will learn a lot of new things every time we communicate.

Second, be serious, careful and not afraid of trouble.

It can't be said that testing is a tedious job. If you are not serious, careful and afraid of trouble, I suggest you not to enter this industry, otherwise, you will be the last person to feel uncomfortable. There is a saying that details determine success or failure, especially for testers. When testers do test requirements, every requirement point in the system requirements report written by developers will become several test requirements (you should verify both normal and abnormal situations), sometimes it feels like playing a game of permutation and combination, but there are too many situations in this game. If you are not patient and careful enough, it is easy to miss the test requirements. And these missing places are often the problem points (developers often forget to consider these places, leading to problems). In addition, the data input of test work is also a very complicated thing. For example, the date validity test can easily summarize 300 to 400 test data. How much do you think all the testing work will be? Even more frightening is that testing is not a one-time job, and regression testing is often needed. All tedious work must be repeated constantly, and testers often reduce the number of test cases for fear of trouble, resulting in incomplete testing. Therefore, being serious, careful and not afraid of trouble are the necessary quality requirements for a good tester.

Third, strong learning ability and good at summing up.

1992, when I was working, I wanted to find a book on software engineering, which was a difficult point. 1997 When I first came into contact with testing, there were almost no books on testing, which greatly hindered the improvement of my level, but this cannot be an excuse for us to improve our level. 1997, the tests we did were mainly functional tests, starting with gorilla tests. Later, on the one hand, we looked for test data from professional books, on the other hand, we summarized our own experience. After 1 year, it basically formed its own testing process and method. We have our own test plan writing method, test case writing specification and test summary method. New testers can improve their level quickly through these files. Later, we also adopted this method when learning testing tools. In the process of learning QTP, one of my subordinates basically mastered the use of QTP after three months of study. Moreover, it also summarizes the problems often encountered in using QTP and publishes them on related websites. Many people think that he is a technical expert, but in fact he is just a novice who has worked for 8 months and studied for 3 months. It is the best way for a tester to improve his technical level by constantly learning new technologies, constantly summing up the problems encountered in practical work, solving methods and sorting them out.

There are two points to note:

1. With the increasing specialization of testing work, the original low-level testers can no longer meet the needs of testing. The use of testing tools, the renewal of testing theory and the application of new technologies require testers to constantly improve their own level;

2. A good tester should not only know the test technology, but also know the development environment, tools and system architecture of the system under test, so as to make a reasonable test plan. In other words, the person in charge of testing should not only know the testing technology, but also know the mainstream development technology, architecture and tools (although they don't need to be experts), which the testers should constantly learn and summarize.

3. Master the theory of examination.

Development tools are changing, testing tools are changing, the system under test is changing, and everything is changing. So what is the most important thing for a tester to learn? Personally, it is the study of test theory. Take myself for example, I used to be a pure software maker, and now I am exposed to many hardware-related tests, such as mobile phone tests. However, no matter what system basic theory you are testing remains unchanged, developers need to provide better requirements documents first. Summary design documents, detailed design documents and requirements documents are the standards for us to formulate test requirements, and also the standards for us to judge whether there are problems in the system, while summary design documents and detailed design documents are the basis for us to formulate test cases. Our method of dividing equivalence classes, boundary value test and other basic tests all need the support of these documents. Of course, each different type of test has its own characteristics. For example, the test of mobile phones requires you to have a certain understanding of communication theory (that is, the system environment), so a good tester must master the test theory in quantity. If you think your test theory is good enough, then answer the question about the difference between performance test, load test and stress test.

4. I can't speak clearly, but the charge is ahead

Some of my testers always like to give me attention, but never consider how to achieve it. Their favorite sentence is, you see how smart I am, I can see the essence of the problem at a glance. I am a good consultant (I used to be like this). I want to tell you that such people have actually fallen into the misunderstanding of technical career. Seeing the problem can show that you have a certain level, but how to solve the problem and how to implement it is the real embodiment of a person's level. This bad habit is now called "Si Qi". Only by solving practical problems can we find out the shortcomings of our own solutions and what new problems will appear, so as to continuously improve our work. For a simple example, I have been using TD for a long time, but today I can still find some new features of TD and apply them to my work to improve my test management. Therefore, I personally think that a good tester will always be the one who is in the forefront, and the best way to improve functional ability is in practical work.

5. Handling of interpersonal relationships

Testing is the flashpoint of a problem, especially for those units whose development process is not standardized. How to deal with interpersonal relationships is a skill that a good tester needs to master. As the person in charge of testing, he often faces short testing time, continuous regression testing, abnormal termination of testing, criticism from leaders, responsibilities of developers, and complaints from testers about time limit and testing environment. How to solve contradictions and deal with these problems is a standard to measure the quality of testers. In fact, a major problem is misunderstanding. The misunderstanding of testing workload between developers and company leaders is a major reason for these contradictions. Therefore, as a good tester, besides having some common interpersonal skills, he should also be a good propagandist. Constantly publicize the testing methods, theories and workload to developers and superior leaders, so that they have a correct understanding of the testing work. Only in this way can we really handle the interpersonal relationship between the testing department and other staff, and the testing of the unit will develop in a good direction.
