Mainframe, MVS and zOS Discussion

Hi,

I've coded a new COBOL program (a batch program). And the program creates the output with the help of a copy book. I'm trying to create a Test-Data and searched yielded that IEBDG can be used to create the test data. I looked at the manuals but I'm not sure how can this program can be amended for your specific application!

Hi,

Please have a look at IEBDG Examples and that should give you the idea what kind of Test-Data you can generate with it. This is a general utility and I think you've amend the output from the IEDEG to suit your specific application.

Hope this helps.

Thanks Anuj. But I've not seen many of the programers using it while it seems to be well documented. In my project people take files from production and use them.

IEBDG is useful to create patterned data where the process is COMPUTABLE by looking only at a single record.

for example You need to test a bunch of checking functions
-numerics
-alphanumerics
-dates
-...
the IEBDG could be a reasonable tool

when relations between different records and files are involved You must extract from somewhere consisting data.

Many applications these days require data in multiple files to be consistent, and data across multiple record types in the same file to be consistent. IEBDG is good at generating test data of a sort, but it doesn't really let you capture the complexities of inter-record and inter-file dependencies, which is why you rarely see it used these days.

Thank you Robert and enrico. This is useful information.
