Hello all,

I would like to know the difference between Unit testing, integration and functional testing. And also what are the testing tools that are more commonly used?

Thanks,

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.
