There are times when developers get stuck with a problem that has to do with version changes. Trying to run the code or test without upgrading the package can result in unexpected errors.
Automating testing is a crucial step in the development pipeline of a software product. In an agile development environment, where there is continuous development, deployment, and maintenance of software products, automation testing ensures that the end software products delivered are error-free.
Web applications continue to evolve at an unbelievable pace, and the architecture surrounding web apps get more complicated all of the time. With the growth in complexity of the web application and the development process, web application testing also needs to keep pace with the ever-changing demands.
โTest frequently and early.โ If youโve been following my testing agenda, youโre probably sick of hearing me repeat that. However, it is making sense that if your tests detect an issue soon after it occurs, it will be easier to resolve. This is one of the guiding concepts that makes continuous integration such an effective method. Iโve encountered several teams who have a lot of automated tests but donโt use them as part of a continuous integration approach. There are frequently various reasons why the team believes these tests cannot be used with continuous integration. Perhaps the tests take too long to run, or they are not dependable enough to provide correct results on their own, necessitating human interpretation.
