7. PERFORMANCE TESTING
• Type of tests execute:
• Data Loading: Generation of sample data
• Load Testing: Execute a given number of users for a fixed period of time
• Normally executed as a baseline between version and releases
• Often used to verify refactored code
• Scalability Testing: Determine the maximum load possible within a pre-
defined limit
• Examples:
• Load Average of 3.5 on all servers
• Transactions responding in under 2.5 seconds
• Stress testing: Locating the breaking point of an application
• Utilized to locate the component least capable of handling the stress
• Often executed to test a new component or refactored code
• Endurance testing: Testing for extended periods
• Used to locate issues such as stuck threads or memory growth
