Title:

Large scale testing in an Agile world: Building quality in the IBM SDK for Java v7

Stream:

Java SIG (2)

Speakers:

Andrew Taylor; Iain Lewis

Abstract:

Followers of Agile development practices will know that with the arrival of new function comes new bugs and new bug fixes. Therefore it is critically important to regularly run existing tests ( to check for regressions) , as well as new tests. Deciding what to run and how frequently to run it needs to be carefully considered, especially when it is not feasible to run all tests on every build.

Testing the IBM Java SE product is a larger task that you may expect - To the casual user it is a black box that provides you with a base on which to run your Java applications, but peek beneath the surface and you find a complex combination of systems including not only the core VM, but also a JIT compiler, Garbage Collector, base Class Libraries as well as bundled value add libraries. Coupled with the wide range of platforms supported and the geographical spread of the development teams the challenge facing the test teams is high.

The talk will cover how IBM's implementation of Java is comprehensively tested across a worldwide organisation in an Agile development environment, focusing on the recent delivery of Java 7 SE. We will look at the problems faced in meeting IBM's high quality standards, and how we address those problems, including covering a wide variety of use cases and the automation required to support this on a large scale.
