----------------------------------------------------------------
[~gwenshap] does the following outline make sense?
$> some_tool <from_version> <m_instances> <to_version> <n_instances>
1. Compile jars into <from_version>_target
2. Compile jars into <to_version>_target
3. Bring up n <to_version> brokers
4. Run tests producer consumer tests with clients from <from_version>_target
5. Bring up m <from_version> brokers
6. Run tests producer consumer tests with clients from <from_version>_target
7. Run tests producer consumer tests with clients from <to_version>_target
8.
{noformat}
foreach(broker: brokers)
Bump up the interbroker.protocol.version
Run tests producer consumer tests with clients from
<from_version>_target
Run tests producer consumer tests with clients from <to_version>_target
{noformat}
9. Cleanup

> Project: Kafka

> Reporter: Gwen Shapira
> Assignee: Ashish K Singh
>
> To test protocol changes, compatibility and upgrade process, we need a good
> way to test different versions of the product together and to test end-to-end
> upgrade process.
> For example, for 0.8.2 to 0.8.3 test we want to check:
> * Can we start a cluster with a mix of 0.8.2 and 0.8.3 brokers?
> * Can a cluster of 0.8.3 brokers bump the protocol level one broker at a time?
> * Can 0.8.2 clients run against a cluster of 0.8.3 brokers?
> There are probably more questions. But an automated framework that can test
> those and report results will be a good start.
