Can anyone help me to explain what basically a MAINFRAME testing is...?. I am doing functionl testing using Mainframe environment that includes ISPF Menu, CICS and different Batch Jobs.I am geting lots of Interview calls for a "Mainframe Tester".
Please provide information about the Mainfrme Testers Profile and what type of questions usually asked in the interview.
I would have some suggestions to offer you as I have been a mainframe programmer and tester in my career.
However, as Joe stated, it depends on what you are doing. Blackbox testing of mainframe programs are fairly straightforward. You are not dealing with "Windows" and object oriented programming. Nor are you dealing with heavy-weight relational databases. Mainframes are designed to handle many simultaneous entries at a very fast rate. I worked in an environment that handles up to 5 million entries at a time with a response time in seconds.
If you are looking at COBOL (bless you) it depends on the environment, i.e. banking, government, and some telecom providers. TPF is used in airlines, credit card companies, and transportation in general.
Batch testing is usually JCL and written to handle "jobs" within code itself.
Give us more info and I will be happy to share my experiences and I am sure others will too.
