You can use several factors to map the success of automation testing. One is the software testing maturity model, which gauges a project’s test process from waterfall (manual testing only) to agile (continuous delivery with automated testing). Another factor is Test Bed Turnover Rate (TBTR), which looks at how quickly and accurately an automation team can set up new test environments and replicate existing ones.
And finally, there’s the industry-standard Test Automation Death Cycle, which highlights the S-shape impedance curve that all successful software projects face when trying to achieve production-ready test automation.
