Testera takes the phrase agentic test management literally. The tests are held as one managed set rather than a scatter of separate scripts, and an AI agent is what drives them, instead of a person working through each case by hand.
That is the appeal of AI-driven API testing: the checks are run for you and the state of the run is easy to read, so keeping pace with an API that keeps changing is not something somebody has to remember to do.
