Test changes in Devops mode -- learning and thinking

The company is gradually moving from agile mode to DevOps Model transformation , What changes have taken place in the work of testers ,DevOps What are the changes to the test , Need to study hard to understand . Record useful knowledge points and good learning materials in the learning process .

DevOps spell

It's development (development) And operation and maintenance (operations) Abbreviation DevOps

DevOps The background ：

To adapt to the market Fast change , Require the enterprise Product fast iterations , Flexible coping The user needs , It's breeding DevOps.

The software development model mainly goes through the following stages ：

  Waterfall model It solves the problem of difficult division of labor and cooperation , But a year 1~2 Time of The publishing process is too slow , And it can't meet the changing requirements .

agile development It solves the problem that requirements change frequently 、 Online slow problem . however The gap between development and operation and maintenance has not been solved , It even adds a lot of difficulties and disputes between development and maintenance .

DevOps On the basis of agility , The main solution is development and operation and maintenance 、 Barriers between operations , More emphasis on end-to-end collaboration from requirements design to production deployment , More emphasis on lean 、 Efficient ; We should try our best to eliminate the waste in every link , The ultimate pursuit of high productivity in every link , To get fast 、 The purpose of high quality online .

DevOps Value pursuit

Value exploration and rapid validation .

Value exploration is to quickly discover and identify the real needs of external customers , Create value points for it .

" Fast verification loop " Ask the enterprise to find the business problem and set the business goal , Fast realization and landing of value points .

The test belongs to " Fast verification loop ", The process requires the development of / test / The role of operation and maintenance closely matches , High efficiency and high texture to verify new features .

DevOps Landing value

Improve business responsiveness

DevOps In the fall to the ground , It can improve the quality of delivery while improving efficiency , The improvement of the degree of automation can improve the responsiveness to the iteration of business requirements , The throughput of research and operation can be improved by geometric level .

Improvement of R & D delivery specifications

R & D teams of different projects or products , Carry out R & D delivery activities on the same platform , Through the pre established process of the platform 、 Rules and other constraints on the delivery activities of different R & D teams , So as to realize the unification of R & D delivery specifications and Standards , Realize enterprise level optimization, promotion and improvement .

Improve the efficiency of R & D delivery

By preparing for the environment in the R & D delivery process 、 Compiling and constructing 、 Code quality check 、 The system test 、 Automation of software deployment and other processes , Reduce the time of manual operation or waiting for manual operation , Comprehensively improve the automation level of R & D delivery process , Improve R & D delivery efficiency .

Improve the quality of R & D delivery

R & D delivery quality assurance from the existing deployment results , Extend to source code quality assurance 、 Test coverage guarantee and other processes , So as to realize the quality inspection and improvement of the whole process from source code to deployment , The whole link improves the quality of R & D delivery

R & D delivery control improved

For the demand of R & D delivery 、 Development 、 test 、 Release and deployment process , Conduct comprehensive data and measurement , Establish quality access control for key indicators , So as to realize automatic technical control , Combined with the existing administrative control , Controlled by a single result , Achieve R & D delivery “ The process + result ” Control and control , Improve management and control .

Continuous optimization of R & D delivery

be based on DevOps platform , Through pipeline process data collection , And further measurement analysis , Realize continuous optimization of R & D delivery process , Both include DevOps Platform optimization , It also includes the R & D delivery process 、 Optimization of standards and specifications .

DevOps Next test changes

（1） Step by step centralized test -》 High frequency quick test

（2） Proportion of manual testing -》 Increase in the proportion of automated testing , Interface automation 、 Contract automation testing 、 Functional automation is in great use , It is used to improve the online test progress

（3） Pay attention to the single link of the test process after the completion of development , Ignore the participation of testers before and during development , Product operation control and quality participation after deployment and launch -》 Emphasize the left shift of the test , Test move right , Testing activities have run through DevOps The whole process , The development team also has to take on the task of testing , The test team will also be connected to the development phase of testing and testing guidance activities

（4）UT Weaken ,API And contract testing is more acceptable ：UT Automation still exists , because UT Maintenance work is huge , And the demand changes quickly , Lead to UT The input-output ratio is out of proportion ,UT Automation weight drops , Use API And the contract 、Mock Wait for the test to replace .

（5） Deployment automation , Grayscale publishing is becoming more and more popular ： The deployment of services has been completely replaced by automation tools , Testing is self-test based on the deployed environment . meanwhile , Grayscale publishing and A/B Testing solves the global risk caused by too fast process , Upgrade and fallback become routine activities .

（6） The tester was right Platform tools are increasingly dependent ：DevOps After the process is completed , More rely on the ability of platform tools to support .

Test shift left and right

Test shift left ： It means that testers participate in various activities in the early stage of the software project earlier , Define relevant test cases before function development , Discover quality problems in advance . Early introduction of the testing process helps prevent defects , It also provides developers with the flexibility to apply dynamic changes throughout the development phase .

Test move right ： It's monitoring directly in the production environment , And get user feedback in real time . In this way , Collect feedback from the user side , Continuously improve the user experience satisfaction of the product according to user feedback , Improve product quality . Moving the test right helps better respond to unexpected situations .

-------- Yes DevOps Some thoughts on testing ---------

DevOps Medium quality assurance （QA） It is no longer the exclusive responsibility of testers , It's the direction that all the staff have to work for . Testers get involved in the development work in advance , Develop test plans with developers ; Developers can participate in configuration deployment ; Operation and maintenance personnel can fill in test cases in the automated test case library ; Testers configure automated test cases into the continuous delivery chain at any time , The common goal of all members is to deliver efficiently 、 High quality products .

Continuous testing requires testers to have a certain coding ability . Testers should not only master common testing tools 、 Use of version control tools and integration tools , And be able to read the code , Check the build log , Constantly optimize the whole test strategy and test cases . Testers must also be involved in the entire continuous delivery process , Ensure the quality of products in the most efficient way .

Testers should focus on the continuous optimization of testing strategies . Automated testing is certainly the most important way to achieve continuous integration , But not all tests are suitable for Automation , Such as usability test and interface consistency test . Testers need to focus on continuous test strategy optimization , By adjusting the proportion of various test cases 、 Increase test coverage 、 Improve the quality of test cases and rapid feedback to improve test efficiency , Achieve comprehensive quality assurance .DevOps How to deal with the era test ？_ Development https://www.sohu.com/a/292575150_753085https://blog.csdn.net/wetest_tencent/article/details/111195675https://blog.csdn.net/wetest_tencent/article/details/111195675
