How to see all testcases of a problem like we do in Codeforces?

In codeforces we can see all test cases and also it tells where testcase is failing. In codechef I even don’t see few pretest cases too. If there is any way please let me know.

CodeChef does not allow us to see any of the test cases.You have to try and figure out. :thinking:

but I think this can be done. If its not there it can be there. But only if we all really demand it.
