A common theme among most software testing organizations is their escalating interest in Test Automation. While test automation has grown in popularity, there are still many myths and biases surrounding it. Such myths can unknowingly create a self-limiting boundary and negatively impact the possibilities of test automation.

Cloud-based testing has become quite integral these days. Most businesses have already done the shift towards cloud-based testing. The traditional testing that was done on the software installed on local servers is now slowly fading away. Cloud-based testing comprises cloud-based test automation as well.
