Hi,
In the Stress testing we test the software against heavy
load such as complex numerical values and large number of
inputs to test whether it is able to carry them out or at
what point it fails.

And as the name is suggesting in the Load testing we
increase the load on the software by connecting the so many
users with the application.

Plz correct me if i m worng...
Regards..
