AI in Regression Testing

Regression Testing is a type of testing in the SDLC process that is conducted after a code update to ensure that the new changes have not introduced new bugs. There is a possibility that the new code may introduce new logic that does not match with existing code and causes errors.

The frequent releases in regression testing make feedback loops better and faster to have a build-up of broken code detected near the production date. Regression testing ensures that with frequent updates, developers do not break things that already function.

Regression testing comes with challenges like time consumption, maintenance, human error, and optimization. Hence, innovation in regression testing can offer a quick and reliable approach. Incorporating regression testing with AI increases the whole testing process thus reducing the time to market.

AI is transforming software testing methods to make it more efficient and accurate. AI-powered tools can minimize the manual testing effort by creating test cases, running tests, and analyzing test results automatically.

AI in regression testing can create automated test cases, optimize code better, and automate all similar flows which saves time. Ultimately, AI regression testing will be free from labor-intensive and error-prone processes.

Traditional Regression Testing Challenges

Regression testing using traditional and manual methods poses some challenges and risks in an agile environment. 

  1. Time-Consuming: A lot of time and resources are wasted on manual regression testing. Running numerous test cases after every update requires significant effort. Moreover, the defect-fixing process can also take longer.
  1. Limited Coverage: The traditional regression testing method can only cover a limited set of test cases, therefore few bugs and errors can be left unseen.
  1. Maintenance: With the technical advancements and growth of user demands, new features are introduced that require to be tested after an upgrade. However, the traditional testing suites fail to uncover the additional bugs due to the increasing complexity of software systems. This can lead to a delay in the upgrade process.
  1. Chance of human error: Regression testing is a repetitive process performed after every upgrade. The same test cases are conducted over and over again in a monotonous manner which can lead to a decrease in attention, and cause human error and bugs to go unnoticed.

Understanding AI in Regression Testing
