MetaAutomation by Matt Griscom
Writing automated tests is the easy part. We’ve all seen demonstrations where the sales engineer creates a test on the fly, then re-runs that test. Tools make it easy to see early progress.
Then comes the day-in-day-out usage of automated tests. Tests pass, but the product has bugs in those areas. Tests fail, for no apparent reason, then pass the next time. Your “automation person” runs the tests and understands the results, but if they are gone that day, well no automation. The next product version comes out, your tests are all broken now…
I’ve worked in test automation for many years, on many projects. Each of these projects were in a different stage of maturity for effective automation. Some efforts were no more than having a tool in place, with 1 or 2 people who could create and run the tests. We waited for the tests to be completed so we could add those results in with the manual results.
Other projects had a lot more infrastructure to make the automated tests valuable to the entire development and test organization. Over the years, I’ve added elements of this infrastructure to a set of patterns that I would apply to new automation projects – and those patterns did add value to the new projects. These patterns include standards for version control of the tests, triggers for execution, management of test data & configurations, test execution farms, notifications, results dashboard, and triage helpers.
Along comes MetaAutomation, by Matt Griscom. This book provides a framework which already contains each of those patterns and a few more that were new to me. Matt’s book provides a framework to develop an effective automation program on any software project.
These patterns range across the phases of the development life-cycle for tests. The patterns start with Prioritized Requirements and how these relate to test case creation.
MetaAutomation provides several useful patterns for test cases, including Hierarchical Steps, combined with Atomic Checks allow for reuse of test assets across test cases – and helps isolate failures when they do happen. Several other patterns relate to checking the test results.
The Parallel Run pattern describes how to run many test suites in parallel, perhaps on the cloud, helping to maximize throughput with reduced duration of execution.
Smart Retry and Automated Triage help address the dreaded task of triaging failed tests. Care should be still taken when using these patterns, we don’t want to mask flaky tests by making it easier to deal with false results.
The automated tests generate tons of data. The Queryable Quality pattern shows how the team can create value from these tests.
If you are in test automation, either building individual tests or leading the effort, this book contains lots of lessons learned the hard way.
I’ll wrap up this review with my favorite sentence from this book: “With MetaAutomation, QA helps developers work faster”. The goal of automation is to improve the overall software development process.
