Built to Last or Built Too Fast? Evaluating Prediction Models for Build Times

摘要

Automated builds are integral to the Continuous Integration (CI) softwaredevelopment practice. In CI, developers are encouraged to integrate early andoften. However, long build times can be an issue when integrations arefrequent. This research focuses on finding a balance between integrating oftenand keeping developers productive. We propose and analyze models that canpredict the build time of a job. Such models can help developers to bettermanage their time and tasks. Also, project managers can explore differentfactors to determine the best setup for a build job that will keep the buildwait time to an acceptable level. Software organizations transitioning to CIpractices can use the predictive models to anticipate build times before CI isimplemented. The research community can modify our predictive models to furtherunderstand the factors and relationships affecting build times.
