| What
is Load and Performance Testing? |
Load and performance Testing are a set of tests targeted at analyzing the system behavior in real life conditions. In order to do that, several parameters need to be considered:
| |
|
Load
of Users in Web or Client Server applications |
| |
|
Load
of Traffic (API, Calls, Networking etc.) |
| |
|
Volumes
of data in database |
| |
|
Simulation
of real life problems (Jitter, Packet Lost,
Latency etc.) |
In order to
simulate those parameters, several tools need to
be used. |
