"Testing a Streams application" points to https://kafka.apache.org/documentation/streams/developer-guide/testing.html Which is a dead link. The working link is https://kafka.apache.org/11/documentation/streams/developer-guide/testing.html But I believe the working link should change to be consistent with the rest of the doc Unsure where do make PR for docs, but if you can do a quick fix it'll be appreciated! Thanks :) Stephane
