I want to test loading Wt Application including the load generated by
Wt(rendering)
Yes I need to simulate actual AJAX sessions.
I tried using WTestEnvironment but is not what I really need.
One thing I use JMeter is that i can simulate number of users accessing it.
So consider the simple case:
I had a Wt application. It works like a charm online.
But when more users are accessing it becomes slow. So I want to find:
When the application becomes slow?
Is it because of no of users?
Is it because of data in db (because my app make a lot of db
operations(insert/update/select)
If I can simulate no. of users I can find out easily that upto what number
of users my application will be in good state?
There may not be tools available for 100% real simulation but its fine If I
can get something closer to it.
So basically I want is testing load on Wt App which runs on server and need
to find wheather it really need to be in a cloud
