Continuous testing is crucial in today's fast-paced software development world to ensure quality and speed. It involves testing the quality of software at various stages of the release pipeline, including initial stages, before release, across environments and devices. Continuous testing enables businesses to approach quality evaluation at multiple points, cutting down manual methods and streamlining processes with automation. Without continuous testing, a continuous delivery model will remain unfulfilled. It helps save production costs by catching bugs early, providing actionable feedback, faster deployment, efficient testing, low risk, and scalability. However, it also has its challenges such as lack of test support in software, absence of standard tools, insufficient testing infrastructure, and scaling issues. To overcome these obstacles, businesses must invest in continuous testing to reap its benefits and achieve a successful continuous delivery model.
