Software Testing SIG: Automation level below 25% even after 30 years of software testing. Why? Do we need a different approach?
Today’s test automation tools across all vendors and even product generations have one thing in common: The adopted technology for automation is script based.
Even products that sell a “script less” automation approach typically use visualization mechanisms to hide the scripts away from the testers.
The automation paradigm we are in is script based and that put us to where we are – a relatively low automation level.
The root problem is the script itself! It takes technical personal to be developed and ultimately requires individual framework-programming.
All in all, a parallel software development project is the result, which requires high maintenance and grows exponentially with the automation attainment level.
Consequently, with a test automation level ranging from 15% to 25% the “effort break-even” between automation and - going back to - manual testing is met! In other words, with today’s technology going beyond 25% automation is more costly than manual testing.
Hypothesis: Stable test cases become reality if the technical steering of the system under test is being generated from the business-view of an application at runtime and not vice versa.
Solution: Business driven Dynamic Steering – a model driven testing approach.
The Business driven Dynamic Steering concept is the ability to steer the system under test solely from cognitive test case specifications, specifications in a human language that require no scripts.
Thus, test cases can be designed, specified, automated and maintained by non-technical testers.
By eliminating the root-problem of test automation – the script – and elevating the task of test automation onto a business level, the maintenance problem is eliminated too.
It slashes maintenance cost to the possible minimum. Thereby, an automation level for functional software tests of up to 80% is practicable.
Gartner believes that model-driven testing approaches will become the dominant format in five years.
