Type Parameters:

T - Type of validating record

All Implemented Interfaces:

Enclosing class:

TestDataMatchers

public static class TestDataMatchers.MultipleSplitDataMatcher<T>
extends org.hamcrest.TypeSafeDiagnosingMatcher<Iterator<T>>

Matcher for validating test data from multiple splits.

Each collection has a pointer (iterator) pointing to current checking record. When a record is received in the stream, it will be compared to all current pointing records in collections, and the pointer to the identical record will move forward.

If the stream preserves the correctness and order of records in all splits, all pointers should reach the end of the collection finally.
