"Hi, A good approach is to run the requests you are trying to model through fiddler.  Then run JMeter through fiddler and compare the difference. My tips are use a cookie manager, and a header manager.  Check the values you are passing…"

Martin Lewis replied to Martin Cavallero's discussion What could be better to studdy as an extra knowledge for a Tester?
"I would say a useful skill is to understand pattern matching using regular expressions.  Understanding of regular expressions will allow you to be more flexible when using other tools that facilitate these, JMeter, Wireshark etc... and would…"

"Hi Adrian, In my experience, I would say that automation can be extremely useful for developing regression packs that can run as part of a continuous integration cycle. They are useful for providing a snapshot and a confidence level for how a…"

Approaches to developing performance test models

Hi,I'm currently developing a set of baseline tests which aims to measure performance changes different versions of software on our test systems.  At the moment we have a skeleton set of tests which test a small subset of the system.  These are tests are not an accurate representation of live environment. The challenge is to improve these tests and try to model a subset of the live system.I’m wondering on which approach I should use when creating a set of models?My thoughts so far:1. Look at a…See More
