-----------------------------------------
Summary: Create standalone MetaStorage implementation for test
purposes
Key: IGNITE-19093
URL: https://issues.apache.org/jira/browse/IGNITE-19093
Project: Ignite
Issue Type: Improvement
Reporter: Andrey Mashenkov
Assignee: Andrey Mashenkov
Fix For: 3.0.0-beta2
*Motivation.*
Some components depends on MetaStorage API and doesn’t tested well.
In tests, we either have to create 100500 mocks, which doesn’t implement any
quasi-real behaviour (e.g. we skip serialization step), or have to implement
end-to-end test and start-up real nodes.
See {{DistributionZoneManagerConfigurationChangesTest}}
Here, initialization of all the mocks looks longer than the tests themselves.
And we copy-paste this boilerplate code everywhere, when we need a bit more
than stupid stub.
*Suggestion*
Let's
* create standalone version of MetaStorage for test purposes, which will just
push raft command directly to a metastorage listener.
* replace boilerplate code in tests with new metastorage implementation.
