I want to create one SQL based contest on HackerRank. I have created questions but i am bit stuck on test case format. I don’t know, what is the format for test case creation. Can anyone help me , like how to create or what should be format of test case on hackerRank ?

I am expecting that, I just want format for test case so it will get accepted whenever someone participate in my contest , when he solve question correctly his answer will get accepted. Overall this will be get handled by backend but tell me what should be format for test cases.
