Continuous Integration is the combination of any number of the available tools used to improve quality of both code and process. In this session we will look at these available tools and how these can be used. We will also look at Continuous Integration in general and CruiseControl in particular, at how to set it up and built a platform for robust and high-quality code. This session is a must-see for development leaders and technical managers alike, to understand the available options and the advantages offered by this approach.
