I have an interview for mainframe testing position I mentioned in my resume that I have known CICS JCL DB2, But I have worked some customized Mainframe Platform, Hence I may not answer well in my interview. Any application testers, can you explain your roles (detailed description)) in your project from top to Bottom clearly .
Eg: Test cases writing
Where/How to take test case input data.
JCL statements alter as per requirements
View the result
How/where to execute the test cases
Consider the above steps and Let me know the full procedure of testing,,, But your answer should cover JCL , CICS , and DB2.
