10: 00 interview, came out at 10:02, the question is really too

Two years of software testing , Over the past two years , From the beginning of the hazy understanding of the test , Now the train of thought is gradually clear , It also makes clear its own development direction . Although the testing theory and testing tools as well as testing technology have been strengthened , But I still don't feel deep enough .

In recent years, I have been doing tests in outsourcing companies , Know last year 12 month , Determined his idea of going to a big factory , So , I have been constantly improving myself . little does one think …

From outsourcing , I didn't expect the algorithm to die in another factory

Since joining this company , Working overtime every day , A lot of money , So I put up with it . little does one think 8 Monthly notice , Everyone is not allowed to work overtime , Wages are falling 30%, Suddenly there are people who can't afford to eat .

Fortunately, a brother pushed me to an Internet company , Excitedly meet the interviewer ,q The front is still a very happy answer , I didn't expect several questions to kill me ：

• What are system bottlenecks ？
• What is concurrency ？ stay lordrunner in , How to do concurrent testing ？ What happens if the rendezvous fails ？
• In your previous work , A software bug （ Or call it Bug ） What is included in the record and how to mention it - Deliver high-quality software defects （ Bug ） Record ？
• What are the criteria for the end of the test ？
• What are the performance test indicators , Do a performance test on a login function , What are the indicators , How to measure the maximum number of requests that can be processed at the same time

• What are the characteristics of orthogonal table test case design method ？
• What are the considerations of requirement testing ？
• One client has 300 clients and three hundred clients have 300 clients to put pressure on the server , What's the difference? ? ?

It's a lot harder , Just didn't answer , I knew I'd take a good look at the study notes and road map given by a big man .

In order to help programmers change jobs and interview 、 A promotion and pay increase 、 Career dilemma , Improve your technology , This article gives you a complete set of quick learning methods and notes covering testing all technology stacks . So far, we have received feedback from seven or eight netizens , It is said that the interview asked a lot of knowledge points .

The content involves the ： Test theory 、Linux Basics 、MySQL Basics 、Web test 、 The interface test 、App test 、 Management tools 、Python Basics 、Selenium relevant 、 Performance testing 、LordRunner Correlation, etc

Experience sharing of software testing posts in large factories
