Introduction of the importance of testing to raise a testing trophy for your front-end application.

I’m a front-end developer and I work in a web agency. I love this job because I have the opportunity to develop many projects from scratch and therefore continuously learn new development concepts.

But I’m often working on 3 or 4 projects at the same time, so it’s hard to keep up with each one of them.
