"Core values of testing" and "super complete learning guide for 0 basic software testing" summarized by test engineers for 8 years

I am now a student with 8 Years of experience as a test engineer , What is the value of testers ? I've been thinking . This problem is in the fifth year of employment , It was only last year that it gradually became clear .

The core value of testing , I think it's continuous technical investigation , Provide quality feedback as quickly and comprehensively as possible . Split into several keywords ：“ continued ”,“ Technical investigation ”,“ As quickly and comprehensively as possible ”,“ Quality feedback ”.

“ continued ” It means that testing is an iterative process . Test the branch of a certain version , Most of them are not difficult , The problem is to plan for the long term , Manage test data and use cases , And automated scripts , Planning for performance and safety testing . When necessary, , Testers need to take on the role of process improvement .

“ Technical investigation ”, It's my analogy of the testing process . Because it's an investigation , So we should collect information spontaneously , Early intervention . Because it's a technical position , So I won't resist learning code , Don't be afraid to discuss technology with developers . I will update my testing technology and toolbox from time to time , Always remind yourself , Constantly arm yourself with knowledge .

“ As quickly and comprehensively as possible ”, It means that testers cannot find 100% problems , There will inevitably be some thoughtlessness and omissions ; Plus time is limited , How to improve test efficiency , It is also a problem that we need to study and think repeatedly . Testing is the same as development technology , There are also professional tools and frameworks ; Testing is the same as product design , It also requires user thinking , Deep understanding of the business . If you can have both “ Development ” and “ product ” The long way , Then leave “ Fast and comprehensive ” The closer the test goal is .

“ Quality feedback ”, It means that the main output of testers is quality feedback . Found out Bug, Do you want to repair , When will it be repaired , It's not up to the tester to decide . Quality needs to be built by the whole product team , Not from the test . Quality , It's not just the test ; Poor quality , It's not just testers who have problems .

These statements , I don't know how many colleagues will resonate . There are many stories behind every point .

0 How to switch to software testing ？

This should be a problem that all newcomers will face , So I combine my own experience , Made some summary and learning methods , I hope it can help you .

Here are five parts that I have summarized

First step ： Cognitive preparation

Before you start to learn , First of all, we must be clear about our understanding of industry and learning ：

• For new students , If you can go to a big company, don't go to a small one , Don't believe the myth that small companies are more exercise ;
• Don't rush into outsourcing in order to reduce the difficulty , When we push in , The test manager of a large factory sees that those who have outsourcing experience should not ;
• To enter the testing industry, you must learn a language , Those who think that there is no need to write code for testing or are more exclusive to writing code , We can make a detour ;
• Technology is the foundation of your foothold , But don't think technology is the best , You can get 100% Respect for ;
• While constantly learning, we should also actively participate in the communication in the industry , Like salon 、 Lectures, etc , It's more reliable for friends to push than for overseas investment resumes ;
• Education is very important , Project experience is fatal , English is a bonus ;
• Learning is long feedback 、 Anti human , Don't expect quick success in the short term , Don't believe 35 The nonsense of unemployment at the age of ;
• Communication skills are as important as technology , This is true in any industry ;

The second step ： Specific learning route preparation

Be sure to have your own learning direction , The goal is to do T Font talent , When ensuring the breadth, we must also have one or two specialties , Only in this way can you stand out in the interview .

I roughly divide it into 2 A gear ：

• a monthly salary 5-9k： From starting with zero foundation to being able to find a job
• a monthly salary 15-25k： Testing, performance testing and automated testing

The first stage ： a monthly salary 5-9k, Just entered , Learn how to test the function first ！

For new people with zero foundation , We must learn first Basic theoretical knowledge , After having a certain computer foundation and software testing foundation , Then do requirement analysis and use case analysis , So this stage focuses on laying the foundation and writing test cases

Learning goals ： Master basic testing theory 、 Preparation and management of various test documents 、 Operation of database 、 Meet the needs of most enterprises

Definition of software testing 、 Life cycle 、 Workflow 、 Demand analysis ;
Design of test cases 、 To write 、 review ;
bug The basic knowledge of Zen and the use of Zen ;
test plan 、 Preparation of test report ;
SVN、Git The use of version control tools ;

Take care of the basic requirements above , We already know that we can do specific combat content , It's better to find one first at this time web Test project Go and do it , If a project gets hold of , Follow the procedure below ：

Release the project for approval , Establish a project team to divide the work ;
Requirements review , Learn how to read requirements documents , Conduct demand analysis , List the test points ;
Tidy up test points , Write test cases , And then use case reviews ;
Perform the test , Such as function 、 Interface 、 Taiwan before and after 、 Compatibility 、 database , For the discovery of bug Submit to Zen ;
analysis 、 summary 、 Write test report ;

After a complete run of the process , We can only say that we have mastered the overall testing process , But it's still not enough to find a suitable job , Want to learn to do functional testing , The following is also a must ：

Linux Relevant skills

Operating environment 、 command 、 mount this database 、 Deploy test environment, etc

Database related skills

Various command usages 、 Field 、 Additions and deletions

Interface testing related skills

The basic theory of interface testing 、http agreement 、 The test method ;
Interface test requirement analysis 、 Use case writing 、 review ;
The mastery of several tools ,jmeter、postman、soupUI;

APP Test related skills

install / uninstall 、 offline 、UI、 Login and other test content ;
Compatibility test 、monkey、fiddler Grab the bag ;

OK, I've done this , Congratulations, you've been able to send your resume to find a testing job ！

All of the above are theoretical and documentation capabilities 、 As long as you are willing to recite 、 Ken write , All can be mastered independently .

I know all the above , Can only be said to be able to get a job , But now the industry has higher requirements for recruitment , Handle automation or performance testing , To get 10k Above the monthly salary . All of the above are theoretical and documentation capabilities 、 As long as you are willing to recite 、 Ken write , All can be mastered independently .

The second stage ： a monthly salary 15-25k, Get the performance 、 automated testing , Acquire the ！（ I am also at this stage, but I belong to the group with relatively little experience , That's why 20k）

Let's start with performance testing , There are many misunderstandings and pain points in the industry ：

• It just doesn't work , It is impossible to give suggestions for R & D and operation and maintenance personnel
• Can't locate the problem , Lack of clear logic and data to prove value
• Performance testing tools ≠ Performance testing
• Performance testing technology system is backward （loadrunner）, We need to embrace open source software

If you want to solve these problems , So performance testing you have to learn ：

The concept and process of performance testing ： Analysis of common problems 、 Popular tools 、 The project design
Performance testing tools ： jmeter Tool use 、 actual combat ;jmeter multi-protocol 、 Expand and customize ; Distributed pressure measurement and task scheduling ;
Performance monitoring ： Performance monitoring system and monitoring data acquisition
Performance implementation ： Distributed service pressure measurement , Scene design 、 Scene execution ; Correlation analysis of test results ,TPS、 response time 、 Thread correlation analysis , Correlation analysis between stress and resource utilization
Performance analysis and report ： jvm Debugging and system debugging ; Performance bottleneck analysis

Performance testing you can get to this level ,15k That's all right , If you can grasp the following automated test learning content , That would have a direct impact on the monthly salary 25k！

Get it done Python perhaps Java Language , Suggest First from Python Starting with , Study first Python Basic grammar of .

web End of the automation test ： selenium install 、 Recording 、 Handle ;web Control 、JavaScript Script 、PO Pattern ;
Mobile APP automated testing ： appium Use 、 Recording 、 Element positioning method ;APP Control positioning 、 Interaction , Parameterized use cases ;appium Problem location analysis 、 Source code analysis 、 Secondary packaging ;
Automatic test of server interface ： Interface automation test framework request; Interface request construction 、 Assertion ;json/xml request 、 Response assertion ;headcookie Handle 、 Certification system ;

The third step : Community interaction , Broaden the circle

I will use my remaining time , To participate in some communities , Communication with peers , Learn from the big boys , After all, it's the fastest way to learn to stand on the big guy's experience . Just learn a little every day , If you stick to it, you will find that software testing is very easy ！！

Step four : Choose learning materials

• adopt B Station search for relevant videos to learn , However, it is suggested to find an experienced one to help you .
• Some other free videos , Some courses of software testing can be searched in Tencent class , There are some free open classes .
• Go to some famous testing forums 、 Search for relevant information on official account , such as 51testing、testerhome、 Official account programmer Yifan et al .
• Pure dry goods sharing , I learned to collect test resources before , Already classified . If you don't want to sort out by yourself, you don't know the learning direction at present , You can pay attention to the public at the bottom of the building ️ Card No ️️️️️ Programmer Yifan will have a set of teaching resources and related documentation resources taught by meituan architects for everyone to learn .

Step five ： In the interview

All I do is ： Brush the surface , Then summarize what questions are asked , Then remember , Is the basic knowledge of computer , Network problems , Easy to test , Memorize the code questions , Because my foundation is poor , I understand the train of thought , Then recite the code questions

It is suggested that no matter what the size of the interview , If you don't want to be abused by the interviewer, don't want to , Only brush the surface test questions and make comprehensive preparations , Of course, in addition to this, we need to lay a solid foundation in our daily life , In this way, no matter what kind of knowledge the interviewer has to chisel into the dead , You can handle it too

Combined with practical experience from reading articles , Summarize and sort out a set of interview materials , The content covers the contents I mentioned below . Prepare to share with students interested in software testing .

What good is that , The advantage is that many questions are mastered very skillfully before you know it , Whether it's concept or principle , The foundation is more and more solid , Learning is getting faster and faster , The important thing is that the interview is getting better and better , What caused you offer, More and more big , It will lead to your self-confidence getting better and better , The most important thing is that it will make you more and more interested in learning , At this time, you will think of ways to learn , To improve yourself . Because I have tasted the sweetness of learning , This is a series of positive feedback .

Friends who need it can get it here , Pay attention to the public at the bottom of the building ️ Card No ️️️️️ Programmers can check the specific content by themselves ！
