Hi Sai,
There's no much on the subject on the internet yet.
We are using the ability of the mainframe to execute jobs via a FTP connection using the "quote site filetype=jes" instruction.
Then we use a modified version of the robot framework FTP library to drive our test.
It pretty much works setting up jobs, submitting those jobs, monitoring its execution and at the end verifying the results (could be compare files or verify database information).
Initially our setup is focused on the testing of batch applications (No CICS tests yet)
