Of the seven levels of software testers, it is said that only 1% can achieve level 7

Some people say ： Software testing is the most important low A little bit of work . Some people say ： To a certain extent, the salary of the test position can only stand still and cannot be improved , Others say ： The testing industry is less technical than development , Easy to replace .

This is actually the biggest misunderstanding of the testing industry . The test can be deep or shallow , Narrow or wide , Oxfork is rarely tested , Many people who talk about the test can't mention a few bug.

Zhihu respondent Chenfu has been doing testing work at Microsoft for six years , He summarized several stages of the tester , You can see how many stages you are in .

Although I have switched to development now , After all, I have been in this field for six years , It seems that I still have the opportunity to speak here .

At first I came into contact with the test purely by accident , When Microsoft came to our school for an interview, only those who did the test were willing to ask me . But after a while, I gradually fell in love with this position . Tell me about my past experience .

** Just like development , Experienced and inexperienced tests play a very different role in the team .** From the actions taken in case of problems encountered during the test , I have observed that there are several levels that testers can reach ： Insert picture description here
1. Open one bug;

2. Look for additional information such as design documentation and history , Make sure it's a question , Then give a detailed bug Repeat step ;

3. Make some refinements to the reproduction steps , Be sure to reproduce bug The minimum steps ; If possible , Automate the reproduction steps ;

4. Try to identify the problem by studying the code ;

5. Try to give a fix;

6. Analyze the cause of the error , Propose some standardized methods to detect similar problems , such as stress,fuzzing wait ;

7. Be able to define corresponding data analysis methods for standardized test processes , It can ensure that both development and project managers can get the information they need to control the quality status .

So as a tester , What is our goal ？

My goal for myself is all that I can control bug from 1 Achieve 4, In at least two cases, I can even achieve level 6.

I have been at Microsoft for more than six years , I've seen it in many departments. It always achieves the level 7 Test of , Tests that can achieve this state , No one dares to say that their skills are not good .

For developers , If you have a person around you who can deal with most bug Achieve level 4 Test of , I believe that the development work will be much easier .

Even if it's catching bug There are also many kinds of .

Catching a group of monkeys and casually clicking on the keyboard is a test , Seriously step by step through various technical means （ Code coverage 、 Pressure test 、 Security analysis, etc ） Step by step is also a test .

As a technician , Which one do you trust ？

I think most people will choose the latter , But what I want to say is that in practice, many test teams will unconsciously become the former .

Why? ？ Because the test does not understand the product design , So I instinctively choose the easiest thing to do , But ask them ： How much did you measure ？ How confident ？ They are all stupid .

I'm not saying that the monkey test is meaningless ： On the contrary , It can catch many blind spots in our thinking . But if your entire team lives entirely on monkey testing , It is absolutely impossible to give you a reliable result .

Then the officials will inevitably ask , The Daniel test and the number of Daniel teams ？

Unfortunately , In my personal experience , The fact is that among the testers I met , At most, you can only achieve level 1 It's not uncommon to have testers .

Can do 3 Many people think our testers are quite good , As for the team with multiple Daniel tests, it is really rare （ The proportion of Microsoft headquarters is much higher ）. Insert picture description here
Yes , Don't be surprised , This is what happened to me at work . But notice , This is not to say that the company is spending money on waste , It is the current situation that will inevitably result in the initial stage of the industry without professional testing education . We all started from this state , They all need time to make progress .

Maybe someone will ask ： This is not to compete with the development ？ Yes , you 're right . But why not rob ？

What is our purpose ？ Yes bug Or do better products ？ If your whole goal is to open more bug, That's really simple .

Real examples , I've seen colleagues test automated code bug Finished product bug Of , His theory is to ignore bug What is it? , Drive it out first , As for whether it is a product problem, a test code problem, or even an environmental fault, it can be slowed down , Anyway, he is not responsible for pointing out the reason .

Actually , It is impolite to ask a colleague to do this or that , But this kind of driving without doing anything bug Besides, work style is delaying the work of all colleagues .

As part of a team , Testing takes an extra minute on the product , Sometimes it can save a few days of development work , Because the test is the most familiar with this bug People who , Development needs to be analyzed from scratch .

—— Of course , Conversely, development should try to bring testing into the development process , Let everyone know the details of the progress of various functions . This kind of cooperation can also greatly reduce the time for testing to redesign the use cases when the product design changes .
