tests: updated names for the tests

Some test cases have the same test case name.
To get rid of it, I decided to change test cases names
contained same names.
Please check my logic, how I give them names.
Usually trying to give name same as a directory folder.
There are still more test cases which necessary to change,
but I will make changes by small steps.
