selenium

Digg's Andrew Bayer has just written a blog describing how we use Git, Hudson, Selenium, Puppet and Gerrit to manage continuous deployment at Digg.

Andrew describes how we get developer commits to production quickly and safely using a combination of automated packaging and staging, web based code review and automated testing (unit and selenium)

i'm currently working on re-engineering many of the development processes at digg. we're adopting a number of practices from the agile world that complement the type of development that we do. these practices include: build automation, automated deployment, daily scrums, short releasable time-boxed iterations, simple design, refactoring, and just-in-time specification.

we've decided to be agile about our adoption of our new agile processes, introducing them incrementally, measuring the results along the way and iterating as necessary.

as we worked through the cascading dependencies of our adoption path, it quickly became clear that automated testing had to be a cornerstone practice if we were going to make a success of the others.
