Unittest feature class validation update

[Omarelsherif010]

added .vscode to .gitignore file and now working on the unittest itself

[Omarelsherif010]

something wrong happened, and I am trying to figure it out. Skip my commits for today, I will come back the right files

[Omarelsherif010]

Now we detect the correct orientation for the feature class and ensure the validate function works well. (check last commit)

For now, the validate function checks on the orientation. What else should we test inside the unit test to make the feature valid?

I thought about testing roles inside the validate function and checking them inside the unit test!!

What do you think?

Note: I have closed PR #422 during solving vscode files problem

[Omarelsherif010]

fixes #420
