Continuous integration for open source web applications on GitHub

This diploma thesis provides a comprehensive view on graphical web user interface testing during continuous integration. It focuses on open source projects published on GitHub that use Docker containers for their deployment. First part of the work is an overview of free cloud servers for the integration of open source projects. In addition, the work includes an overview of automated testing tools that are based on the Selenium WebDriver library. Attention is paid to tools supporting the development of test scenarios according to the agile methodology called behaviour driven development. Another part of the thesis describes the design of technical solution that allows integration of graphical web interface testing into the process of continuous integration for open source projects. The proposed solution uses Travis CI as cloud integration server and a standalone website to store reports and other information on past integrations. Automated tests are defined using the Robot framework and executed using a Docker image, which is published on Docker Hub. The use of the proposed solution is demonstrated by its implementation and deployment for the open source project EasyMiner. This project is developed at the University of Economics Prague in DIKE department. The implementation includes the creation of a test suite with scenarios according to the behaviour driven development methodology.
