Ultimate Goal

Provide a set of template scripts to streamline the execution of load tests

during project development cycles.

Load Testing - Why?

1. Measure an application’s typical response times under

normal load conditions

2. Evaluate performance degradation when facing

incrementally heavier load conditions

3. Identify performance bottlenecks under concurrent usage

Load Testing - Best Practices

● Generate seed data to help identify database bottlenecks

● Set up ramp-up periods and pauses to generate

incremental load and emulate users’ think time

● Use distinct user accounts to avoid contention over session

data retrieval

● Monitor queued requests to pinpoint infrastructure limits

● Design your tests to be idempotent in order to compare

results

Additional Considerations

● JavaScript code won’t be executed by JMeter

● Adjust number of concurrent threads to the hardware

resources running JMeter

● Isolate test script custom data using request defaults, user

variables and CSV data sets

● Use parameters to instantiate variables via command line

● Use “View Results” listeners when fine-tuning test scripts
