Open Source Summit + ELC North America 2020

Several years ago increasing code complexity, community turn over, and wider use of Apache Traffic Server (ATS) were causing reliability issues in production use. The community decided to make this a high priority for future efforts. The payoff from taking testing and reliability as first class objectives is now evident This talk is about that journey, looking at the tools used, the tools built, and the improvements from that work. Ongoing and future efforts will be discussed, because testing remains a critical part of delivering a reliable product. All of these tools are available for other open source projects and almost all for any project.

ATS is a C++ project and therefore these tools focus on C++ code support, although many of them are applicable to other languages. These include
* Catch for unit testing.
* AuTest for black box testing.
* Coverity, clang for static analysis.
* Using different compilers for cross checking.
* Use of continuous integration for driving testing.
* Community efforts and outreach to promote testing and testability.
* Lessons learned from failed efforts.
