Travis & Coveralls

Continuous Integration and QA

During the development process of an application or before deploying code to a server, it is very important to verify the quality of the code. Continuous Integration (CI) is a development practice that allows us to verify checked-in code using an automated build and to detect problems early.

Travis is a continuous integration tool that, once configured, takes care of these tasks and let us save a lot of time (that we can use to actually write code). Travis-ci.org is an online service that works with GitHub (it requires we use GitHub as the repository for our code), and once we have connected the two accounts and configured a very simple file in our projects, it’s automatically triggered when we push on our GitHub repository.

Coverallsruns tests and checks the percentage of the source code that is covered by tests, producing a nice report that shows us the percentage for every single file/module and even the lines of code that have been tested.
