Define test objectives, key user actions, and target load levels.
Create performance scripts based on realistic user journeys.
Set up the test environment and distribute load generators.
Run load tests and capture response metrics and logs.
Gather throughput, latency, resource, and error rate metrics.
Review data trends, thresholds, and service level objectives.
Identify system, database, or API constraints impacting performance.
Apply optimizations and re-run to validate improvements.
The goal of performance testing is to ensure the WEB Application consistent, scalable, and reliable performance under the expected number concurrent user load before its first production deployment.
