The key to successful test automation is to focus on tasks that maximize the return on investment (ROI), ensuring that you are automating the right tests and automating them in the right way. This is where test automation strategies come into play.
Greetings folks! With the new year finally upon us, we’re excited to announce a collection of brand-new product updates. At LambdaTest, we strive to provide you with a comprehensive test orchestration and execution platform to ensure the ultimate web and mobile experience.
Entering the world of testers, one question started to formulate in my mind: “what is the reason that bugs happen?”.
“Test frequently and early.” If you’ve been following my testing agenda, you’re 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. I’ve encountered several teams who have a lot of automated tests but don’t 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.
The fact is not alien to us anymore that cross browser testing is imperative to enhance your application’s user experience. Enhanced knowledge of popular and highly acclaimed testing frameworks goes a long way in developing a new app. It holds more significance if you are a full-stack developer or expert programmer.
