Continuous Integration (CI) is a development process in which developers incorporate or integrate code changes into a shared repository quickly, usually many times a day. Thereafter, the verification of each integration is done through an automated build and automated tests. The reason for performing regular continuous integration is that it helps teams to identify defects and fix them quickly. When making small changes in the mobile app, sometimes it introduces a new defect that is easy to recognize with continuous integration.
Continuous testing in DevOps is a type of software testing where the software is tested at every aspect of the software development life cycle. The purpose of continuous testing is to evaluate the software’s quality at every step of the ongoing delivery process by testing early and testing often. One can involve stakeholders like DevOps, developers, QA, and the operation system in the continuous testing process.
The benefit of continuous testing is that code is consistently developed, delivered, tested, and deployed. For instance, Whenever a developer examines its code in the source code server like Jenkins, he/she will be able to execute an automated set of unit tests in the continuous process. In any case of test failure, one can reject the build and give information about it to the developer. If the build successfully passes the test, QA servers for exhaustive functional and load tests are implemented to monitor the performance. The execution of tests is done in parallel. After passing all tests, the software is deployed in production.
