I'm a senior test engineer who has been outsourced by Alibaba and now has an annual salary of 40w+. My two-year career changing experience is sad

I graduated from an ordinary university majoring in machinery ,14 Years of graduation ,16 I changed my career in 2000 , At present IT Software testing in the industry has 3 More years , The position is Senior Software Test Engineer , Coordinates Shanghai …

I think now I have a little qualification to talk about the topic of career change ; I hope before you decide to change your career , First, find out whether it is your inner love or impulse to change careers ;

If job hopping is another good opportunity , Well, in most cases , Is to start over , High risk . That's why there's an old saying ,“ Job hopping for half a year , I have been poor for three years ”, Although it is absolutely right , But it makes sense . under these circumstances , Compared with continuing to die , Switch , Maybe the worst choice . therefore , Before you consider changing careers , You might as well spend more time , Several industries that are interested in you , Take the initiative 、 Comprehensive understanding and screening .

I had a chance to change my career + luck , Why do you say that? , I graduated with a bachelor's degree in mechanical engineering , I know there is no good job after graduation , It's basically the sales of the machinery industry , Or technical drawing , Or go to the first and second lines of the factory , But as an undergraduate , None of the three wants to , Some people would say , It's good to make mechanical technical drawings , But otherwise , First, I didn't learn any technology at all in school , It's all books , Just pass the exam , To be honest with you , I'm a good player in the League of College heroes ,haha.

Career change experience

Later, I worked in Shanghai for more than a year , One month on average 6,7000 about , Share a flat with colleagues 1500 A small single room , Get rid of the overhead , There's basically nothing left , Every time I see a luxury car driving on the road , High end restaurant consumption , People who spend a lot of money are suitable for me. I can think , How can I stay in Shanghai , Go on like this , In the end, I'm sure I can't go on , Go back to your hometown , But back home , What can I do ？？？

Then it was luck , It was decided to find another way out , I just don't know what to do , There happened to be a client , The relationship maintenance is OK , He just does IT Of , Know what I think , He introduced me to a man he knew IT Training institutions learn .

I now sum up this in one sentence “ Choice is greater than effort ” 了 .

My learning process at that time was learning + employment , Full time study , About three months , Because I'm an undergraduate , Age and education are appropriate , Plus I learned well , The employment agency over there is also very responsible , So the monthly salary of employment at that time was just 1w whole , Already very satisfied ！ Now it seems that compared with other institutions, the time is very short , It seems that many institutions have to 5,6 It takes months to finish school and get a job , This is a calculation , I earned my tuition for a few months , Other institutions don't seem to have graduated yet , And I don't know their employment salary , But my income must be not low .

Now more than three years after changing jobs , Revenue growth , It also needs to constantly learn industry technology , It is impossible for those who want to change careers to earn a high salary all their life , In especial IT Technology industry , It's simple , The same way, if you don't advance, you will fall back .

My career transition , Several suggestions can be summarized ： How did you change your career ？ Is it easy to change careers ？ In all things, we must make plans , If you are not modest, you will be ruined , Not prepared in advance , In the end, even if you change your career, your life won't change much . Changing careers is not an easy process , The skill accumulation and learning process after changing careers is not easy . Changing careers is just the beginning , After a successful career change , You still need to do a lot of accumulation to get what you want , If you want to be opportunistic , Then it is recommended not to change careers .

Heartfelt suggestions

So as a person who came here , If you want to change careers , My suggestions are ： Be sure to think about changing careers , Don't change careers just by half pushing , There must be insufficient motivation to change careers , Can't learn ; Second, when changing careers, you must have knowledge, recommend reliable ones, or have an in-depth understanding of the employment situation of the organization , Especially how to ensure employment , Don't listen to sales , Even online reviews are written by the Navy , Ask the people who really have to learn there , Their evaluation is the most true . Because many agencies do a lot of advertising , But employment is bad , Spend the same money , Half a year , Finally, the employment salary is very low or can't work at all , Shop bully , You can't handle him , In the end, you lose a lot of money + Time ！ No one can bear the loss .

As a tester , I'd like to share with you all these years , I want to sum up the technology , Share your notes on the skills you need to master as an advanced automation Tester , I hope to help friends who want to go all the way on the road of Technology ！

1、 Basic theory of software testing ：

Software testing theory knowledge is the theoretical basis and support to carry out testing work , It's a skill that must be mastered at a very important stage of testing .

• Encapsulate the test framework ： Integrate Appium、adb Tools such as 、 Predefined exception handling 、 Record Appium journal 、 Screen capture 、 Build a multi-purpose testing framework

8、 Advanced software test automation —— Continuous integration and continuous testing

Continuous integration and continuous testing are built in iterations 、 Test the product and fix it Bug The process of . It helps the team identify defects early in the development phase , The defects are usually relatively less complex , And it's easier to solve . Through continuous integration and continuous testing , The risk of errors can be minimized as soon as possible , And accelerate the delivery of better quality software .

• version control Git： Background introduction 、 The deployment environment 、 work area 、 Staging area and submission area 、 Branch creation and merging 、 Resolve conflicts 、 label 、 config And aliases 、 Local warehouse and remote warehouse 、 GitHub And code cloud

According to this learning architecture route , Constantly explore and improve , Break through the bottleneck of technology , so to speak , It's a process that's going to kill you , But as long as you get through it . Life will be much easier in the future . It's just that it's hard at the beginning , Just take the first step , You're halfway there , When we look back on this journey after it's finished , You're bound to feel a lot . I've come a long way , To get more high paying jobs , It pays off , It can also be regarded as a recognition of my ability , Really proved their value . At least after tax 30+ My salary is satisfactory in my current state .

These materials , For friends who do software testing, it should be the most comprehensive and complete war preparation warehouse , This warehouse also accompanied me through the most difficult journey , I hope it can help you ！ Everything should be done as soon as possible , Especially in the technology industry , We must improve our technical skills . I hope that's helpful …….

I wish everyone can get the heart offer~~
