To facilitate the development of robust, error-free code, Apex supports the creation and execution of unit tests. Unit tests are class methods that verify whether a particular piece of code is working properly. Unit test methods take no arguments, commit no data to the database, and send no emails. For example:

Sam Newman provides a succinct definition of microservices in Building Microservices : “Microservices are small, autonomous services that work together.”. Codebases grow as we write code to add new features. Code related to similar functions starts to become spread all over, making fixing bugs or implementations more difficult.

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.

“Hail the QA Engineer” may be clickbait, but it isn’t controversial to say that testing and debugging will rise in importance. First, one of the cornerstones of QA is testing.
