> DRILL-4437 introduced a unit test framework to test a non-scan physical operator. A JSON reader is implicitly used to specify the inputs to the physical operator under test. 
> There are needs to extend such unit test framework for two scenarios.
> 1. We need a way to test scan operator with different record readers. Drill supports a variety of data source, and it's important to make sure every record reader work properly according to the protocol defined.
> 2. We need a way to test a so-called mini-plan (aka plan fragment) consisting of multiple non-scan operators. 
> For the 2nd need, an alternative is to leverage SQL statement and query planner. However, such approach has a direct dependency on query planner; 1) any planner change may impact the testcase and lead to a different plan, 2) it's not always easy job to force the planner to get a desired plan fragment for testing.
> In particular, it would be good to have a relatively easy way to specify a mini-plan with a couple of targeted physical operators. 
> This JIRA is created to track the work to extend the unit test framework in DRILL-4437.
>  
> Related work: DRILL-5318 introduced a sub-operator test fixture, which mainly targeted to test at sub-operator level. The framework in DRILL-4437 and the extension would focus on operator level, or multiple operator levels, where execution would go through RecordBatch's API call. 
> Same as DRILL-4437, we are going to use mockit to mock required objects such fragment context, operator context etc.
