I have made a notepad in c and i want to add find & replace feature so i just want some test case for that feature so that it works fine in notepad editor.
I'd suggest you do the following:
- Start with a list of things the feature is supposed to do. You should already have this from when you created the feature. If you have a function specification, use that to create the list.
- For each item on the list write some test cases to test the item.
- Edit your question and add the list of tests you created. Ask if your test cases are good or not.
