PERFORMANCE TESTING - TLE

• testing measures that evaluates the speed, responsiveness and stability of a computer netowrk, software program or device under a workload

  Performance testing
• performance test focuses on

  speed, scalability, stability
• Determines whether the application responds quickly

  speed
• determine maximum under load the software application can handle

  scalability
• determines if the application is stable under varying loads

  stability
• helps develops understand the behavior of a system under a specific load value

  load testing
• involves testing an application or device under extreme workloads to see how it handles high traffic or data processing

  stress testing
• also called endurance testin, simulates a steady increase of users over time to test systems' long-term sustainability

  soak testing
• a type of stress testing that evaluates system performance when workloads are substantially increased quickly and repeatedly

  spike testing
• measures performance based on the software's ability to scale up or down performance measure attributes

  scalability testing
• is a type of software testing, where the software is subjected to a huge volume of date. is is also reffered to as flood testing

  volume testing
• normally the initial time it takes an application to start. this shoul generally kept to a minimum

  Long load time
• the time it takes from when a user inputs data into the application until the application outputs response to that output

  poor response time
• it cannot handle the expected number of users when it does not accomonade a wide enough range of users

  poor scalability
• obstructions in a system that degrade overall system performance. its either codeing errors or hardware issues cause a decrease in throughput under certain loads.
