What are the 3 techniques of DevOps regression testing?

In a specific DevOps test scenario, the team can consider using a regression testing strategy so that whenever the source code undergoes modifications or changes, regression testing can be performed accordingly. It also becomes an essential activity to run regression tests whenever any new functionality has been introduced. Time can be saved considerably in a DevOps test environment, if regression test is performed strategically so that bugs can be detected quickly and easily. When the source code is debugged inside a DevOps environment, the platform of regression testing ensures that the bugs that have been fixed do not lead to more issues. In this article, you will get to know about the three techniques of DevOps regression testing.  

The strategic relevance of regression testing in DevOps: 

1. Selective regression testing: Only selected test cases are executed from test suite when there is a specific change in the code. The complete test need not be run. The code outcome can be tested and checked at a faster pace. The effect of both changed code and previous code can be effectively compared. 

2. Partial regression testing: That specific part that could have been affected is selected especially when changes in the code takes place. New parameters are added to the existing system to ascertain if the system is working as usual after the modifications are being made. Critical bugs can be easily detected in the current code. This testing technique can be quickly performed. 

3. Complete regression testing: The entire application is examined in this type of testing technique. When 100% coverage of test cases needs to be performed by QA testers then complete regression testing can prove to be beneficial. It is usually used in scenarios where the project owner does not want to make drastic changes during the testing process. Test cases and test scenarios can be provided with 100% coverage using this testing technique.    

Solutions provided by regression testing: 

1. Managing the environment: If regression testing needs to be properly implemented on the new application code then it needs to be tested in an environment wherein the production environment is accurately mimicked as closely as possible. In a global enterprise environment, this means that thousands or even millions of customers are mimicked and upon that a dizzying network of firmware versions, applications and network of servers. 

2. The significance of test metrics: Powerful analytic and reporting tools can be used for feeding and organizing real-time data to dashboards and reports allowing decision makers, stakeholders and testers to know results and progress at any given moment.  

3. The value of automated tests: A variety of automated software testing tools can be considered. Based on the organization’s network, methodology, interface or application, an automated test solution can be used. For example, if regression tests needs to be regularly performed on an online interface then Selenium is a good solution that can be considered.
