Thank You Tanya.
I read the suggested article .
in the article's notes it's written that:
"
When you change the object hierarchy in Name Mapping, this also changes the fully-qualified syntax for addressing the corresponding objects in your tests (you can view this syntax in the top right of the Name Mapping Editor). Therefore, you also need to update your tests to use the new syntax of mapped names and aliases, otherwise the tests will fail with the “Object not found” or similar errors."I undestand that if I change the Name Mapping object hierarchy I also need to update my tests to the new syntax.
My question is , if there is a simple way to find and replace all the Instances of the object in my test in order to change them all at once
