JavaScript libraries like jQuery have empowered Web developers to create very complex Web interactions and animations in the browser using simple syntax and few lines of code. Unfortunately, it has also become easier than ever to write tangled JavaScript code that is untestable while being difficult to read, extend and maintain.
“
Obtiva has an amazing grasp on test-driven development and JUnit and has probably the most extensive Java knowledge of any company I know. I feel that the information and practices that were given the course will be invaluable.
