    I think, everything should be ready now. Although while performing testing, I have found something that I think is not ideal.
    
    If we use this code:
    
    ```python
    env.generate_sequence(1, 5)\
             .map(Id()).map_partition(Verify([1,2,3,4], "Sequence")).output()
    ``` 
    
    The Verify() function will error out with `IndexError: list index out of range`, this is not ideal, since it should raise a Flink testing exception. I could also try to fix this if needed.
