Description
Some of the api-commands under com.basho.riak.client.api.commands do not override the equals()-method (nor hashCode()).
Context
For unit-testing my client-code I would like to mock the RiakClient, especially its execute()-method:
// example assumes mockito
FetchBucketProperties fetchBucketProperties = new FetchBucketProperties.Builder(new Namespace(TYPES_BUCKET_NAME)).build();
FetchBucketPropsOperation.Response fetchedBucketProperties = mock(FetchBucketPropsOperation.Response.class);
when(riakClient.execute(fetchBucketProperties)).thenReturn(fetchedBucketProperties);
But, since I cannot record the mock with the same command-instance as created by the caller of riakClient.execute(), my recorded invocation never matches.
Affected commands that I detected so far: FetchBucketProperties, StoreBucketProperties, StoreIndex.
Expected Behavior
When I mock as in the example above, invocations of riakClient.execute() with a FetchBucketProperties for the same Namespace should match my recording.
Actual Behavior
Since FetchBucketProperties doesn't override equals(), my recording does not take effect.
Possible Fix
Well, implementing equals() and hashCode() for the affected classes would help. I'm trying to provide a Pull request within the next week.
