Types of testing

• Burn-In Test - 
  • run for an extended length of time in order to identify any potential problems. 
  • It aims to reveal any problems or defects within a system by operating it in the most rigorous, extreme or extended working conditions. 
• Stress testing 
• testing beyond normal operational capacity, often to a breaking point, in order to observe the results. Reasons can include:
• to determine breaking points or safe usage limits
• to confirm mathematical model is accurate enough in predicting breaking points or safe usage limits
• to confirm intended specifications are being met
• to determine modes of failure (how exactly a system fails)
• to test stable operation of a part or system outside standard usage
• to test how system recovers / behaves post break down? data loss? security holes?
