We know that robot framework provides us suit setup, teardown and Test Setup, teardown option while we execute out Robot test script. But, I am stuck in a situation where I have few test cases for which the test teardown is different and some other set for with some other set of Tear down. The main constraint is I have to execute all these test cases in the single suite at a stretch to make some dependency test cases to execute.
How to do custom Test Setup/Teardown with respect to different test sets in the same Test suite?
As suggested by @Bryan Oakley, read the manual. In the section about test setups and teardowns you'll find this sentence which I believe answers your question:
Individual test cases can also have their own setup or teardown. They are defined with the [Setup] or [Teardown] settings in the test case table and they override possible Test Setup and Test Teardown setting...
