Answer / aashi

Mainframe is technology...like we have JAVA,C++etc...For
mainframes we have COBOL as Langauge,JCL (Job Control
Language),DB2 Database is used.
Mainframes Testing is nothing but to test a program of
mainframe, which would be written in COBOL,will run with
the help of JCL and will be using DB2 database.
Please correct me if I m wrong.

Answer / lenin

OOps.. Im happy on seeing the above answers.. As a
Mainframe tester for the past 3 years let me brief what it
is..

In a very high level would say 'Testing a Mainframe
Application Manually / Automatically'

Similar to the manual testing, Mainframe testing also
follows SDLC (Software development life cycle), in which
the testing involves after the development phase. Once the
code which involves the mainframe (Coding may be from
COBOL, SAS, REXX ) coding is comleted, the corrsponding
compilers will be set up. If it is a COBOL code, a JCL is
required to compile and to execute the code.

The tester will be provided with the application (Cobol
code and the corresponding JCLS). As the tester having
his / her requirements in hand, he would have done with the
test cases based on the business requirement. So he will
prepare the test data to satisfy the business requirements
and execute the Cobol module using the provided JCL.

If he meets the Expected result the test wil be pass or
fail if not. If the test is failed, probably he would raise
a defect in the code and fix the same. The testign life
cycle goes like this.

If the tester gives sign off from his end, it is ready to
be promoted for User or into production.

Answer / satish

For mainframe testing HE/SHE should be aware of the
navigations in mainframe application(ISPF).
The testing process would be same as other applications.
We may need to work on mainframe applications
like ....COBOL,JCL,VSAM and DB2
It would be good if you know the utilities like FILE-
AID,CHANGEMAN and XPEDITER

Answer / vijay

Hi Friends I workied in Mainframe project in 1 year 3
months. I am sharing my experience with you all.

first of all we now navigation of the application in the
mainframes.

I did tested the insurance project in mainframe project,

after promotion of the code, we will set the parameter file
(this is not required for all projects,its based on
projects).

then i will do some transactions or modifications based on
the requirements. then I will request the supporting team
to run the Jobs.

after running the jobs, I will check the DB2 tables and
where I am expecting the expected results. If all working
fine then Ok.Other wise there is a defect.

Answer / sathish

hi,

For Mainframe Testing the basic stuff that you need to know,
1) First we need to get RACF ID (Appliction ID)
2) You want to know about the ISPF commands
3) Required Dataset (This is nothing but the table name)

How it works: JCL

For example i am working in one application, Here Mainframe
is the Front End and the Oracle Database is the Backend. IT
Support will run the batch/job in the ETL Data Stage
application to push the data from mainframe to DB.

Role of tester here is need to validate the data in the
Database against the Mainframe.

The most important thing here is you need to know some
basic shortcuts when you are using Mainframe.

For Example:

Command line-----------cols (Gives the postion number in
the header)

B ---- Browse
E ----- Edit
V ----- View

This is just a sample. If you want to know contact me at
sathishmultitech@gmail.com

Thanks

Answer / prathik

As vijay said, im most of the domains we are follwing the
same things..
some projects needs gui testing also, if there is an
intraction between the db2 tables and the front end with
the help of JCL jobs.

Answer / victor

Mainframe testing is the process of testing an cobol code
through JCLs and inturn which will use DB2 tables for
fetching the data.
Often it is done after a development of a code by the
developors upon the requirement of the business and the
tester with the requirement doc will write valid test cases
to fulfill the requirement of the same.
Also one more testing is the testing of the data feed comes
from the business for its correctness thru cobol programs
or JCL

JCL - Job controlling language.

Which is used to control the batch jobs in running environment.

ISPF - interactive system productivity facility

Which is used to allow us to access the JCL commands.

Through commands we can manage viewodify and run our application.
