Further, at an early stage of the development lifecycle, developers need to execute tests after each stage, involving, writing and execution of tests, along with the refactoring of the code.
Moreover, as the development process, progresses, and with the gradual development of a software product, the need for frequent execution of testing activites, also arises, so as to achieve the desired quality. However, with the stipulated deadlines and the limited budget & resources, most of the organization, unwillingly, compromises, either with the quality or with the time, thus affecting the smooth continuous delivery process.
This brings, continuous testing in the picture. With continuous testing, you don't need to compromise. It is an effective testing, carried out, in the direction of automating the testing process and incorporating it, in the development process, as soon as possible. The window of continuous testing, runs in the background, with affecting the development process, and automatically execute the tests, to reveal the issues, at the earliest, thereby helps, in shortening the duration of the release and ensuring the continuous delivery process.
Continuous testing is the uninterrupted execution of automated tests while being part of the software delivery process, facilitating immediate feedback based on the business changes associated with the product and mitigating risks before they proceed to the next SDLC stage. This end-to end automation of tests helps to integrate QA into the Devops processes to maintain continuity and thereby addressing the overall challenge of quicker development cycles. The scope of Continuous testing is pretty huge with validation of functional and non-functional requirements of the product. It involves API testing, unit, integration and system testing of the software, all done under a simulated environment with automation.
It's an assessment which touches upon mitigation of risk factors and queries related to optimal test coverage which ensures the readiness of the build to pass through the next stage in software development life cycle.
A holistic analysis to ensure that all the working processes in the product are in perfect alignment with the rapidly evolving business demands. This includes tracking the most recent trends which can potentially harm the internal codes because of their alien nature. This also includes the enhancement of defect prevention capabilities
This involves identifying high risk areas and also tracking if the existing requirements are being met satisfactorily or are in need of further verification.
Employing automated testing for defect prevention, risk prioritisation and code analysis. Aim is to achieve more with each iteration.
To ensure accuracy in yielding of test outcomes and the maintenance of test information, it's important to have the services of a good data management tool.
In order to save on testing time and cut the costs incurred in establishment of test setups, continuous testing can enable simulation or virtualization of different test stages.
Along with the job of continuous delivery process, below given are some of the advantages of the continuous testing.
