Functional testing to automated testing, sharing ten years of automated testing experience

Xiaobian has contacted too many testing peers , Because most of my peers have been doing manual testing before , Now I'm eager to do automated testing , There is no lack of work 5 More than years of colleagues . I I have been engaged in software automation testing for nearly ten years , Come into contact with Bottom server 、 API 、Web、APP、H5 wait , I know a lot about automation . Let's share my personal experience here .

If you don't know anything about automation , I'm yelling about automation every day , It's all empty shouting .

 

therefore Want to automate , First Learn about some common problems in automated testing .

What is automated testing ？

automated testing , seeing the name of a thing one thinks of its function , Automatically complete the test work .

Through some automatic testing tools or self-made wheels, we can realize the manual point before simulation / Write the work and verify the results to complete the whole testing process , This kind of testing process , It's automated testing .

Because every automated test is case It all starts with manual testing , So the basis of automated testing is manual testing .

Why automated testing

1. Automated testing saves cost ( According to the project )
2. Some test projects are hard to implement by hand ( The cost of manual work is high )
3. The project quality process requires

The advantages of automated testing And disadvantages

advantage ：

Regression testing is more convenient and reliable ; Can run more , More cumbersome testing , And fast and efficient ; Some manual tests can be executed, which are quite difficult or impossible , Such as a large number of concurrent users ; Better use of resources , It has the characteristics of consistency and repeatability , Automated test scripts are completely reusable ; Enhance the credibility of the software ; Testing in multiple environments, etc .

Inferiority ：

Maintenance costs are relatively high

System development time may not be shortened

Still rely on manual testing , Many problems can't be found

Automated test classification

According to the classification of test purpose, it can be roughly divided into ： Function automation test , Performance automated testing

According to the test object, it can be divided into ：Web Application testing ,APP test , The interface test , Unit test, etc

Function automation

The purpose of testing is to find out whether the functions in the software meet the requirements of users , Practice has proved , Often we implement UI The purpose of automated testing is not to find defects in software systems , More is to verify whether the system can run normally .

Besides, it can be based on UI Conduct automated tests , We can also test based on the web service interface provider , Interface based functional testing is common , It's also a very effective means .

In addition, it can be tested based on the basic code of the system , Such as unit testing , Integration testing phase , This phase of testing is also called white box testing , We can go straight to DAO,Service Service to test , Common testing techniques here include Junit, TestNG, Mock, Stub etc. .

Performance automation

Performance automation testing is to simulate high concurrent load through testing tools for stress testing , In order to find the bottleneck of software system running under high load , Include Performance bottlenecks in the application itself , Network bottleneck , Server hardware resource bottleneck , Data storage server, etc , Usually only with the help of automated testing tools , Common performance testing tools include , Loadrunner, Jmeter, Ngrinder, Gatling etc. , No matter which testing tool , There are basically three parts ： Test script management , Test scenario configuration , Monitoring results .

Similar to functional automation is , Performance test work objects can also be user oriented UI layer , Or service interface provider , You can even directly face the underlying business logic layer , The vast majority of performance tests conducted through the user layer simulate the tests closest to real user scenarios , It is also the inevitable stage of performance testing .

The process of automated testing

 

Common tools for automated testing

below I A brief list of common tests , And the best testing tool for it .

Performance testing tools :Loadrunner,Jmeter,Ngrinder,Gatling, There are some differences and limitations in each testing tool , You can refer to relevant documents for details .

Function test tools : Selenium, QTP

APP Automated test tool ：Appium, UI Automator, MonkeyRunner, Android UI Recommended for testing UI Automator, yes Android Automated testing framework provided by , Basically support all Android Event operations .IOS Applications can choose to use Appium.

Interface automation testing tools ：Junit,TestNG, OKhttp, HttpClient,Spring Restful etc. , Some coding experience is required , Of course, there are also some A tool for success , such as Postman,HttpRequester,SoapUI etc. .

Unit test tools ：Junit, TestNG, EasyMock, Mockito, JMockit etc.

Since what conditions are suitable for people to do automated testing

Have code capabilities

Master a development language , java、Python、ruby、c#

Be familiar with the tested system

For example, you are web test , You have to understand js、css、html、xpath

You are a mobile test , You have to have Android Development basis and iOS Development infrastructure , Meeting debug app

You are a C/S You need to be familiar with the test TCP、IP agreement

Master a set of automatic testing framework ( Tools )

such as selenium/appium ;nunit/testng ;robot framework/cucumber

Good at learning , To know what it is to know what it is

IT The industry is changing too fast , The frequency of emerging things is fast , Only keep learning , To keep up with the times , Not eliminated .

In a word

Learn a development language Java/Python, Learn a testing tool selenium/appium, Master a testing framework , More precipitation , need System information 【 Private letter my key words “999” Free access 】. To learn more , And then seize the opportunity , It's easy to transform automated testing
