Fundamentals ofContinuous IntegrationTestingPresented By Cygnet Infotech Pvt. Ltd.
Continuous Integration Continuous Integration aims at minimizing Integrationtime to enable quicker time-to-market. The continuous cycle of Code->Build->Test->Deploy isfollowed to enable high-quality and bug-free releases. Most integration bugs are identified and fixed on aregular basis to avoid last-minute delays. The working code is committed frequently so roll-back iseasy in case of major new defects.

Continuous Testing By applying a lean workflow, continuous testing can beimplemented. It is best to select continuous testing tools based on thedevelopment language and nature of the application. The tool will watch the code for changes andautomatically runs the tests after compilation. Then thetools will provide feedback through a notification system.
Automated ContinuousRegression Testing Regression defects might become the hardest to fix ifthey are not identified and isolated at an earliest. Continuous Regression tests are automatically run in thebackground of an application to provide rapid feedbackon defects and failures. The code is well-tested so that the number of regressiondefects are minimized. Some automated test tools capture the changes inapplication to evolve and monitor effectively.
Continuous PerformanceTesting Even when the functionality is tested on a regular basis,performance might be neglected leading to applicationfailure after deployment. It is essential to carry out continuous performance testingso that the application can be studied for: Reponses times Changes in Speed Consistency Changes in Reaction Time
Continuous Load Testing It is important to follow continuous load testing to makethe application ready for use. Making it an iterative process of Plan-> Test->Analyze->Fix will help tweaking and tuning effective. Continuous load testing helps reuse test cases andestablish clear performance related goals. Load testing must start with small incremental scenarios,and the finally become one whole package.
Continuous Scalability Testing Building a bridge and then testing it for extension is not veryproductive. Similarly getting an application on track withouttesting it as to how much more it can take is a failure. With continuous scalability testing, you can find out andimprove the below attributes of your application: Throughput Network Usage CPU Memory Usage Continuous Scalability Testing helps reduce business risksand quick identification of application’s performanceattributes.
To Summarize While continuous integration development process can helpdeliver a high-quality software in short time, it cannot berendered complete without implementing continuous testing. The overall Continuous Integration process helps reduceassumptions and assures a healthy software throughout. With better project visibility brought in by CI, effective time-critical business decisions can be made. Finally when Continuous Testing based on ContinuousIntegration is implemented, the confidence on the end-product/application is high.
