Hi,

Unit testing :

A complete cycle of each module will be tested

ie for PP Right from requirements to planned orders /production orders

confirmation .

Integration testing:

Here cross module testing will be carried out.

ie PP and MM integration

After confirming production order a GR is made /billing is carried out

and delivered.

Functional testing:

This testing is carried out to see whether the system can with stand l the loads during processing by users.

Stress test and volume test.

Hello All,

May I ask you if there any FREE tools or LOW COST tools that can be used in Stress and Volume Testing in SAP Systems? Are there any tools recommended aside from Load Runner that can be used in Performance Testing?

Please advise. Any inputs are highly appreciated.

Thank you so much in advance guys.

There are no Testing tools available except for Performance Testing. Performance Testing is carried out, by Load Runner, to find the system performance under different Loads (no of users accessing system simultaneously).
