DESCRIPTION

View webinar: http://www.eurostarconferences.com/community/member/webinar-archive/webinar-88-improve-the-process-by-taking-control Testing is one of the few overarching aspects of software delivery. Done well it is almost invisible. Yet in reality almost all aspects of a successful release require test input. Despite this testers often give developers freedom to select automation test strategies and are happy to let release managers co-ordinate releases, while reducing their role to nit-picking software. This session will examine how focusing on testing enabled Songkick to overhaul their entire build and release pipeline, and move from safe, controlled releases to continuous deployment. Contrary to common belief this approach could only succeed by drastically improving testing. The unique skills and knowledge that a tester holds is exactly what is needed to avoid testing gaps, prevent test duplication and most of all educate the development team about working with risk. Whatever your development approach this session will help you identify and explore ways in which your testing skills can, and should, be used to drive radical process improvements.

Make the checks fast◦ < 10 minutes to complete

Checks must run locally

Run tests in the most sensible order

Fast feedback

Page 16: "Improve The Process By Taking Control" with Amy Phillips

Never release if the build is red

Green builds must mean the tests have passed

Trust the test results

Releases

Page 20: "Improve The Process By Taking Control" with Amy Phillips

It ended up being about more than just releases…

Everyone cares about testing

Fast and maintained automated checks

Bug fixes often take just minutes

Page 21: "Improve The Process By Taking Control" with Amy Phillips

What made it work Agree on an end goal

Stay risk focussed

Strong communication throughout the whole team

Use problems to drive positive change

Testers already have these skills

Page 22: "Improve The Process By Taking Control" with Amy Phillips

By managing the people and activities which make up the development process we can manage the risk level of a release.

Testing provides information to this process, which makes better-informed decisions possible.
