Quality assurance

To ensure the highest quality, we maintain a complete test suite with a stable 100% of code coverage for each of the packages. As of October 2018, this means over 9600 tests and the number is growing.

Such an extensive test suite requires a proper continuous integration service. We use Travis CI as a build platform. This service ensures seamless and fast developer experience and allow us to focus on the job.
