Continuous Integration Services I Like

Posted on July 20, 2015 in Blog • 2 min read

The term “continuous integration (CI)” refers to a process that builds, assess and tests code on a frequent basis.

Today continuous integration is a starting point for agile developers and widely used.

Every project I’m working on starts with a setup of continuous integration pipeline. I’m a big fan of agile developing, that’s why I was always searching for tools or services to help me develop my projects better and faster.

Here is a brief summary of services, selected over the years, I use in my projects, all of them are free, provide a badge you can embed in your website and are really easy to use. As example I will show the services I use on Ghiro, an open source image forensics tool. is a service to help you track your code coverage over time, and ensure that all your new code is fully covered.

This is of great help to focus you on writing tests (yep, I will do…)

For example, this is the dashboard you get for Ghiro:

DRONE.IO is another continuous integration tool, I think it is more customizable than Travis-CI although I use both. is a code quality service, it monitors your codebase for metrics and trends. It runs checks against your code to look for errors, code smells and deviations from stylistic conventions. It finds potential problems before they’re problems, to help you decide what and when to refactor.

It is a good service, although it is not so much configurable (i.e. you can’t mark false positives), it could help to keep a code quality in your projects.

For example, this is the dashboard you get for Ghiro, there are same false positives I can’t mark as accepted:

I love this service, I found it of great help. Remember: it is mandatory to keep track of insecure dependencies in your project!

For example, this is the dashboard you get for Ghiro:

Travis CI

Travis-CI is the best continuous integration and building services you will get, any description is pointless, and it is free. Kudos to these guys.

For example, this is the build report you get for Ghiro:
