Functionality should be similar to "Replace All" functionality in MS Word.
A user selects test cases where certain string needs to be updated. S/he enters the string that needs to be replaced & new string to which existing one should be updated. Such update should happen in all steps within the test case.
|I would like...||to update certain text in all test cases|
|So that I...||don't have to spend time in doing same updates in many tests one-by-one|
