Professor of Tsinghua University: software testing has gone into a misunderstanding - "code is necessary"

Have you found that the current recruitment Test Engineer Of JD, Basically all Development content involved 了 ？ such as ：
Do you feel like you can't write code ？ You can't do the test ？

in fact ,**“ The interview requires making rockets , Screw in the screws for daily work ”** Such things abound .

Even if daily work is just “ Dot ” Verification work , I have to take a written exam during the interview , Write a sort algorithm or something on paper .

Software testing has gone into a misunderstanding ——“ Non code ”！

In other words , Software testing is a current trend , The test engineer must write code for any role .

Write code , Increase automation , Let the computer complete the repetitive action , There's nothing wrong with it . But once it's over , become “ You have to write code ”, It is a misunderstanding in the current software industry .

“ Non code ” The formation of misunderstanding , There are several reasons ：

Testing is not valued

I believe in this topic It will resonate with many testers .

Please answer a few questions ：

“ What is the ratio of R & D and testing personnel in the company ？”
“ How long is the software development cycle ？ How much time is left for testing ？”
“ Problems occurred after the software went online , Which team was the first to be asked ？”

A few questions , Basically, men can be silent and women can cry .

The test team must demonstrate its own technicality 、 speciality ？ It should also be shown quantitatively .

Comprehensive learning and research , Follow the code , Is a very direct idea .

therefore , Many testers drop business research , Pick it up IDE Start writing code …

The test team leader doesn't understand testing

This is also a practical problem , Many test teams are actually led by R&D Leadership of , Or the test manager should report to R&D Person in charge Report .

R&D Leadership of ,99% A pure R & D background , It's also an indisputable fact .

IT Technology development , The division of labor is becoming more and more detailed , R & D and testing , There are two different directions .

This will inevitably lead to the problem that the layman is in charge of the layman .

From the perspective of pure R & D personnel , The amount of code is a measure of work , But this standard requires 、 Measuring the work of testing , It generalizes .

The majority of people , You can only understand what you know , Otherwise, apply it to your own understanding .

Too much emphasis on automation

automated testing , It's a good direction , It has replaced a lot of manual labor , Especially in regression testing , Particularly important ！

however , If you feel “ automated testing ” It can solve all problems , That would be an exaggeration .

Fully promote automated testing , This means that the relevant testers must write code .

• How to determine the business coverage of the test ？

• How to judge whether the scope of abnormal use cases is sufficient ？

• How many defects are discovered by automated test cases ？ How much is found by manual testing ？

Answers to a few questions , Speak for themselves .

If there is no good Software architecture , automated testing , In especial UI automated testing , Is absolutely Tired of dealing with all kinds of changes .

The prerequisite for launching automated testing is , Have a good test architect plan .

in summary

Out of the “ Non code ” Misunderstanding , Software testing should return to its essence ： Guarantee quality .

In testing this angle , The essence of software testing is quality assurance , All the work that can improve the quality should be covered by testers , The code is only part of it .

The existence of misunderstanding , As a result, many testers are learning code for code , Did not solve the quality problem , Don't even know the business .

What is more frightening is that many testers do not care about the business , And don't care about technology , It's about thinking about what role to turn into in the next step .

In the field of software testing , The interface test 、 Security testing 、 Performance analysis ……, A lot of work really doesn't need to write code .

Human energy is limited , Full bloom , Often it means “ The eighteen martial arts are sparse ”. Will eventually face 35 Age problem .

With agility and DevTestOps The popularity of the system , The testing industry also began to develop slowly , Various concepts have become popular , Testers may be confused about future development , This is understandable , But still have the ability to think independently , Don't always follow suit , Believe in the celebrity effect .

Lost time , Think about the nature of things , Find the essence , There will be a direction .

The house needs to be built layer by layer , Knowledge needs to be learned at one point one . We should lay a good foundation in the process of learning , More hands-on practice , Don't talk much , The last dry goods here ！ I stayed up late to sort out the stages ( function 、 Interface 、 automation 、 performance 、 Test open ) Skills learning materials + Practical explanation , Very suitable for studying in private , It's much more efficient than self-study , Share with you .
