Also, the fact is only LEFT/RIGHT key navigation is sensitive to NodeOrientation - hence only a subset of tests needed modification. This is the reason I have parameterized the test.

Regarding your suggestion of having forward/backward semantic methods and calling them in tests - 
There are two types of tests -
1. Key action remains same - asserts differ based on NodeOrientation
2. Key action differs based on NodeOrientation - but, asserts remain same

Example of 1 is - test_rt18488_selectToLeft
Example of 2 is - test_rt18591_cell_1

Your suggestion can be applied only to the tests of type-2. I will try to update tests of this type.
