Performance testing is complex, you can’t use just a screwdriver – you need a swiss army knife. I’ve seen yet another performance test tool that sells itself as needing ‘no scripting’ ability.

Performance Testing is hitting the wall

Load Testing is breaking

I’m going to write about something that has been increasingly concerning me.   The current method of Performance Testing – capture network level traffic, inspection, correlate, and then replay, is becoming more difficult.  In the good old days we had simple GET and POST requests.  Then Ajax and Web2 came along, making things a little trickier.  […]
