What is stress testing, performance testing, Security testing, Recovery testing and volume testing.

Stress testing: Testing the system if it can handle peak usage period loads that result from large number of simultaneous users, transactions or devices. Monitoring should be performed for throughput and system stability.

Performance Testing: Testing the system whether the system functions are being performed in an acceptable timeframe under simultaneous user load. Timings  for both read and update transactions should be gathered to determine whether.  This should be done stand-alone and then in a multi-user environment to determine the transaction throughput.

Security Testing: Testing the system for its security from unauthorized use and unauthorized data access.

Recovery Testing: Testing a system to see how it responds to errors and abnormal conditions, such as system crash, loss of device, communications, or power.

Volume Testing: Testing to the system to determine if it can correctly process large volumes of data fed to the system. Systems can often respond unpredictably when large volume causes files to overflow and need extensions.
