Performance Testing is a type of testing to determine how a system performs in terms of responsiveness and stability under various workload conditions. Key aspects include: 1. Performance Metrics: - Response time - Throughput - Resource utilization - Scalability - Reliability 2. Testing Goals: - Identify bottlenecks - Determine system capacity - Validate performance requirements - Benchmark performance ⬆ Back to Top

Common types of performance tests include: 1. Load Testing: - Tests system behavior under specific load - Validates system performance under expected conditions 2. Stress Testing: - Tests system behavior under peak load - Identifies breaking points 3. Endurance Testing: - Tests system behavior over extended periods - Identifies memory leaks and resource issues Example of JMeter test plan: xml <?xml version="1.0" encoding="UTF-8"?> <jmeterTestPlan version="1.2"> <hashTree> <TestPlan> <elementProp name="TestPlan.user_defined_variables"> <collectionProp name="Arguments.arguments"/> </elementProp> <stringProp name="TestPlan.comments"></stringProp> <boolProp name="TestPlan.functional_mode">false</boolProp> <boolProp name="TestPlan.serialize_threadgroups">false</boolProp> </TestPlan> </hashTree> </jmeterTestPlan> ⬆ Back to Top
