This talk covers topics such as:

• Theory of CI testing, where it can help and where not.
• Insights about your repository (Version Control Systems, VCS).
• Strategy (what to test, level of testing and when).
• Human/community aspects and challenges (Open Source Software, OSS).
• Workflows (Make your devs happy).
• Security.
• Examples of production setups.

This talk is slightly opinionated and based on experience gathered through various open source communities and companies.
