I, of course, am looking from a somewhat different – performance – point of view, so not going to jump into details of the discussion too deeply. But I see quite a few people saying, in one way or another, that automated regression testing is the only thing we needed. or there is no API to talk about at all.

For that Keptn already offers integrations with JMeter and Neoload with other testing tool integrations in the works.
