CloudBeat supports 4 frameworks - yet develops it’s own framework:
Oxygen (as a CLI or an IDE) - make sure you try that out for an easy approach that requires little to no knowledge in coding.
Java + Cucumber - this framework has the simple advantage of writing your tests in a certain method - while the person who develops in Java - makes it read the text written in the test - and runs it as an automation test.
Java + TestNG - this framework is the most popular framework in the testing automation world.
MSTest - this framework is supported by Microsoft and written most of it in C#, it is open source and can be also used for unit testing.
