Today’s challenge in 30 days of automation in testing is:
Look up some definitions for ʻAutomationʼ, compare them against definitions for ʻTest Automationʼ.
Celine on the Ministry of Testing Slack channel was in early with this one 
"Tricentis qTest for Unified Test Management | Tricentis
Automated testing is the act of conducting specific tests via automation (e.g. a set of regression tests) as opposed to conducting them manually, while test automation refers to automating the process of tracking and managing the different tests.
Both automated testing and test automation are important to continuous testing, but it’s the latter that really takes the cake on this one."
Over to you, what definitions have you found?
