hachikuji commented on pull request #6070: KAFKA-7773; Add end to end system
test relying on verifiable consumer
URL: https://github.com/apache/kafka/pull/6070
This patch creates an `EndToEndTest` base class which relies on the
verifiable consumer. This will ultimately replace `PlaintextConsumerTest` which
depends on the console consumer. The advantage is that we can the verifiable
consumer exposes more information that can be used for validation. It also
allows for a nicer shutdown pattern. Rather than relying on the console
consumer idle timeout, which requires a minimum wait time, we can halt
consumption after we have reached the last acked offsets. This should be more
reliable and faster. The downside is that the verifiable consumer only works
with the new consumer, so we cannot yet convert the upgrade tests. In this
patch, I've converted only the replication tests and a flaky security test to
use `EndToEndTest`.

> Assignee: Jason Gustafson
> Priority: Major
>
> We have a few system tests which use `ProduceConsumeValidateTest`, which
> relies on the console consumer's idle timeout for shutdown. We should convert
> these systems tests to use the verifiable consumer instead so that we can
> control shutdown more finely and we have more validation options.
