The main focus of unit tests is to focus on small units in isolation. But only focusing on the small units does not touch all the code. So this blog post clarifies the difference between

Having talked to many developers, we found out that there is a huge demand for topics around engineering of SAPUI5 applications. The dynamic nature of JavaScript makes the language very powerful, but it is also

Wouldn’t it be nice to get instant feedback if your application still works after each change? Having the correct setup of your development environment, this can be easily achieved. With local testing, you get instant

Are you scared of making changes to our code? Do you spent a lot of time debugging or maintaining your code? Are you new to JavaScript and do not know the language’s many pitfalls ?

On the last GTAC Mark Trostler (a Google Software Engineer) has given a presentation about testable JavaScript Code and how testability relates to high quality code and adaptivity to requirement changes. You can apply these
