[commons-numbers] 03/03: Test code clean-up

This is an automated email from the ASF dual-hosted git repository.

aherbert pushed a commit to branch complex-gsoc-2022
in repository https://gitbox.apache.org/repos/asf/commons-numbers.git

commit 1b0bfa60cd8ae023fc75eac7f91e97986a887fa6
Author: aherbert <ah...@apache.org>
AuthorDate: Mon Jul 25 10:59:35 2022 +0100

    Test code clean-up
    
    Remove unused assert methods (replace by assertions with
    UnaryOperator<Complex> operation1 and
    ComplexUnaryOperator<ComplexNumber> operation2).
    
    Use final.
    
    Correct typos.
