Core Principles
Abstract: 

As the agile development methodology gets more popular, it is a big challenge to release new versions of components into distributed systems without introducing new faults or degrading system performance. In this presentation, we discuss an effective testing framework we built using record-and-replay and log analysis techniques for regression tests and capacity tests on large scale distributed systems. A stack of open source tools are used to build this testing framework. Through replaying the incoming events and comparing systems responses, we can verify the correctness of the systems. System performance metrics are collected through log analysis in replay for performance criteria check and performance comparison with the previous version of systems. This testing framework is also an example of effectively using open source tools to build a practical application.
