Ten years' experience of byte test engineer directly hits the pain point of UI automation test

When looking for a job, we need to have experience in automated testing , From this point of view, testers will not be embarrassed to say that they are doing software testing . Most testers also use automated testing tools 、 Recording and playback 、 The test script 、 Development of automated testing for gadgets , Then slowly contact UI automation 、 Interface automation 、 Continuous integration , Finally, build an automated testing framework system .
Most beginners of testing are probably most exposed to automated testing UI It's automated , Have also used mobile terminals Uiautomator、Appium UI Automation framework 、PC Internet interface related Selenium、Robot Framework UI Automation framework , Subconsciously, I think UI Automated testing is simple . But after using it for a period of time, there are mixed emotions , Especially when it is really used in work, it is immediately acclimatized , The time of developing and maintaining scripts is much longer than that of manual testing , Do more harm than good , Finally, from regression to manual testing .

If you want to UI Automation can be used in practical work , The following pain points must be solved , otherwise UI Automated testing still has a long way to go .

1、 Demand is unstable , Frequently changed items

UI The biggest challenge of automated testing is the change of requirements , If the interface changes frequently , The script needs to be rewritten , The frequent changes of interface requirements lead to the script writing speed can not catch up with the changes of requirements , that UI Automation exists in name only , therefore UI Automated testing is especially suitable for stable requirements 、 Projects that will not change frequently . The project requirements of agile development are unstable , Changes in requirements often lead to changes in the interface , At the same time, the project cycle of agile development is short , Therefore, agile development projects are not suitable for UI automation .

2、 Develop projects with short maintenance cycles

For one-time development 、 Short cycle projects , in consideration of UI Input output ratio of automation , Not suitable for UI automated testing .UI The benefits of automation are mainly reflected in multiple rounds of testing , Imagine that a project with a short maintenance cycle has fewer test rounds , Such as interface test 1 To 2 Just turn , In this way, manual testing can be used . At the same time, the development and debugging of automated scripts itself requires a certain amount of time , If the project cycle is short , There is not enough time to support script development , There is no need for automated testing .

3、 The development of the tested system is not standardized , Testability requirements are not clear

UI Automated testing is actually simulating manual clicking , Unlike the human eye can directly find the control that needs to be clicked , The program is different , We need to find the control to click in advance , Then let the program click to complete the simulated manual operation . This requires defining some columns of specifications for automated testing before project development , Development engineers follow the specifications when developing ,UI Automation can go on . For example, there is no unique... Defined for the button control id Or text description , The control cannot be found when the automation script is written . If the development often changes the definition of the control casually before different versions , The script that can be executed before will not run correctly later , Need real-time maintenance , Bring high labor costs and become inefficient . Similarly, there are interface parameters in the process of interface automation testing .

What kind of project is suitable for UI Automated testing ？ The following list can be used for reference ： Demand is stable and changes infrequently ; Frequent regression validation is required ;UI Interface stability 、 The interface control definition specification is testable ; Develop projects with long maintenance cycles ; The project schedule pressure is small ; Large companies and platforms ; Most testers in the testing department have script development ability .

At present ,UI Testing is the testing link that consumes the most manpower of the testing team , Most testers' daily work is UI test . therefore UI Automation is very suitable for solving simple 、 mechanical 、 Repetitive tasks , Increase test coverage .

UI Automated testing is more than just writing test scripts , Design is also required , It is not only necessary to consider the execution efficiency of hundreds of use cases , Maintenance costs also need to be considered , Correctness of execution results . We need to understand ,UI Automated testing cannot replace manual testing , It is also difficult to reduce the number of testers , We should not blindly advocate and pursue UI automated testing .
