"Testing Triplets of Achievement" Nice Word isn't it.
Triplets here mentions a very important aspect of Software Testing which looks into the behaviour & attitude of the software/application. Triplets I mean the Performance Testing, Load Testing & Volume Testing.
Performance Testing - Testing is concentrated on the speed & performance of the system in various workloads.
Load Testing - Testing is concentrated on putting the demands to the system and measuring its response time.It demonstrates on the software program by simulating multiple users accessing the program concurrently.
Volume Testing - Testing is done on the databases.It checks the application by increasing the volume of the datas in the system.It checks for 3 parameters of volume of low, equilibrium & High.
