Could anybody please advise if there is any automation tool available which can be used for both regression and load/stress testing.
My understanding is you either buy one or the other,
Please advise if this is correct!!
You should buy either one or the other as load/stress is a totally different test than regression.
I suppose you could try to misuse all automation tools to perform some kind of load/stress test, but the tool you use will interfere with your results.
In my not so humble opinion regarding load/stress/performance/volume testing: if it is not worth doing right, it is not worth doing.
So either get the specialist with the skills and the tools, or forget about it.
Yes that is correct.
Generally, for load test scripts it is time consuming at best to incorporate functional logic. It also creates extra overhead on the player PC.
The verification functionality of automation scripts creates too much overhead to be considered useful for load testing - it would take many, many PCs to create a load.
Some of the big companies support this but you still have to purchase both tools!
