How to learn automated testing?

1） First of all, let's take a brief look at QA Positioning in software development iterations

Waterfall model is widely used in traditional software . The tester's activity area is limited , The time area of the activity is mainly from measurement to online .

In the traditional waterfall model ,QA The space to play is relatively limited , Quality pressure is concentrated in the testing phase . With the expansion of software scale 、 Division of department functions 、 The development of agile iterative model , Most of the Internet or large software projects have evolved into DevOps.DevOps It's a leap in software culture , It emphasizes the product 、 Development 、 test 、 deliver 、 Communication and cooperation in all aspects of operation and maintenance , Extending the agile approach to the entire product . from QA We also have the concept of testing left shift and testing right shift .

2）QA What techniques should we master to do automated testing ？

The theoretical basis of testing

The product form of each company is very different , Therefore, different software development processes have been developed . Most big companies have operations 、 product 、 Vision / Interaction 、 Development 、 test 、 Operation and maintenance 、 Technical support 、 Customer service, etc , You should understand the responsibilities of each role , And understand the logic of the whole product operation . At least we should understand the R & D process of our company and the current mainstream R & D process （ Like agile development Scrum）, And think positively in the process of the project , Form their own software awareness and concept .

General computer foundation （ In fact, it's a university course related to computer science ）

At least one programming language is recommended （C/C++/Java/Python, recommend Python, The cost of learning is relatively simple ）. Compared to specific needs / For domain developers , Testers' requirements for coding technology will be relatively weakened （ Of course, it doesn't mean you don't need geek spirit 、 Architectural thinking ）. involves Web、 desktop GUI、Android/iOS You can learn the corresponding framework from the specific application .

Server side ：

1. White box unit test ：Junit(Java)、unittest(Python)、gtest(C++)

(2)http The interface test ：Postman

(3) Caught tools ：Charles、Wireshark

(4) Pressure measurement ：Jmeter, In large factories, there are some specific written tools that can be used .

(5) Link dependency analysis ： Sort out the dependencies between applications , Provide pressure measurement model , There are also some tools that can be used in large factories .

(6) monitor & Log analysis ： Application stability monitoring , Such as qps、rt, Server load 、cpu Monitoring etc. . Log analysis can do some rule-based error log monitoring 、 Even based on AI The way （ Such as ： machine learning ） Clustering log big data 、 Problem analysis / location .

client （Android/iOS/H5）：

（1）UI：Appium、Macaca、Airtest

（2） performance （CPU/ Memory / Frame rate ）：Android Studio、Instruments(iOS)

（3） stability ：Monkey

（4） Compatibility ： All kinds of cloud real machine platforms
