The test plan is dead!
Well, hopefully. At a STAR West session this past week, James Whittaker asked a group of test professionals about test plans. His first question: “How many people here write test plans?” About 80 hands shot up instantly, a vast majority of the room. “How many of you get value or refer to them again after a week?” Exactly three people raised their hands.
That’s a lot of time being spent writing documents that are often long-winded, full of paragraphs of details on a project everyone already knows to get abandoned so quickly.
A group of us at Google set about creating a methodology that can replace a test plan — it needed to be comprehensive, quick, actionable, and have sustained value to a project. In the past few weeks, James has posted a few blogs about this methodology, which we’ve called ACC. It’s a tool to break down a software product into its constituent parts, and the method by which we created “10 Minute Test Plans” (that only take 30 minutes!)
The ACC methodology creates a matrix that describes your project completely; several projects that have used it internally at Google have found coverage areas that were missing in their conventional test plans.
The ACC methodology is fast; we’ve created ACC breakdowns for complex projects in under half an hour. Far faster than writing a conventional test plan.
As part of your ACC breakdown, risk is assessed to the capabilities of your appliciation. Using these values, you get a heat map of your project, showing the areas with the highest risk — great places to spend some quality time testing.
We’ve built in some experimental features that bring your ACC test plan to life by importing data signals like bugs and test coverage that quantify the risk across your project.
Today, I’m happy to announce we’re open sourcing Test Analytics, a tool built at Google to make generating an ACC simple — and which brings some experimental ideas we had around the field of risk-based testing that work hand-in-hand with the ACC breakdown.
You can check out a live hosted version, browse or check out the code along with documentation, and of course if you have any feedback let us know – there’s a Google Group set up for discussion, where we’ll be active in responding to questions and sharing our experiences with Test Analytics so far.Long live the test plan!
