> Currently, In testing EnsureRequirements's test cases to eliminate ShuffleExchange,
The test code is not in conformity with the purpose of the test.These test cases are as follows:
> 1、test("EnsureRequirements eliminates Exchange if child has same partitioning")
>    The checking condition is that there is no ShuffleExchange in the physical plan.
= = 2 It's not accurate here.
> 2、test("EnsureRequirements does not eliminate Exchange with different partitioning")
>    The purpose of the test is to not eliminate ShuffleExchange, but its test code is
the same as test("EnsureRequirements eliminates Exchange if child has same partitioning")
