Automation frameworks enable automation testers by simplifying the test development and execution activities. A typical automation framework provides an environment for executing test plans and generating repeatable output. They are specialized tools that assist you in your everyday test automation tasks. Whether it is a test runner, an action recording tool, or a web testing tool, it is there to remove all the hard work from building test scripts and leave you with more time to do quality checks. Test Automation is a proven, cost-effective approach to improving software development. Therefore, choosing the best test automation framework can prove crucial to your test results and QA timeframes.
When I started writing tests with Cypress, I was always going to use the user interface to interact and change the application’s state when running tests.
Hey LambdaTesters! We’ve got something special for you this week. ????
I think that probably most development teams describe themselves as being “agile” and probably most development teams have standups, and meetings called retrospectives.There is also a lot of discussion about “agile”, much written about “agile”, and there are many presentations about “agile”. A question that is often asked is what comes after “agile”? Many testers work in “agile” teams so this question matters to us.
The events over the past few years have allowed the world to break the barriers of traditional ways of working. This has led to the emergence of a huge adoption of remote working and companies diversifying their workforce to a global reach. Even prior to this many organizations had already had operations and teams geographically dispersed.
Learn to execute automation testing from scratch with LambdaTest Learning Hub. Right from setting up the prerequisites to run your first automation test, to following best practices and diving deeper into advanced test scenarios. LambdaTest Learning Hubs compile a list of step-by-step guides to help you be proficient with different test automation frameworks i.e. Selenium, Cypress, TestNG etc.
You could also refer to video tutorials over LambdaTest YouTube channel to get step by step demonstration from industry experts.
