Agile Test Automation: Truth, Oxymoron or Lie?
•
1 like•964 views
This document discusses agile test automation and addresses whether it is an essential truth, oxymoron, or lie. It notes that agile emphasizes parallel teamwork between development, testing, and business. While test automation may initially require extensive ramp-up time and skills acquisition, building a library of automated scripts and using programmatic test tools can help achieve faster feedback, consistency, and avoid technical debt. The document advocates automating tests in parallel with development in each sprint to allow for easy, flexible regression testing. It argues that with an evolving approach to automation and a focus on reusing test data, process knowledge, and results, agile test automation can be an essential part of the agile process.
