Do you have 30 minutes to spare? Let's get our hands dirty! We're having a quick hands-on session that will teach you how to create a load test in just 5 minutes. Architecture Expert Rui Mendes will minister to your load testing needs with this very practical and quick exercise. After a few initial considerations on load testing - why they're important, best practices and pitfalls to avoid — you will understand how to streamline the execution of load tests during project development cycles. In this session you will: - Learn how to use JMeter, an extremely powerful and extensible free and open-source tool. - Understand how to create and address a few simple test scenarios. - Analyze the results and understand the resulting metrics. - Get an Expert load testing live demo that you can follow step by step.

Ultimate Goal
Provide a set of template scripts to
streamline the execution of load tests
during project development cycles.

6. How to set up a load test in 5 mins
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

7. How to set up a load test in 5 mins
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

The Tool - JMeter
✓ Free and open-source
✓ Extremely Powerful
✓ Highly Extensible
✓ Community Driven
✘ Steep Learning Curve
✘ Outdated Look & Feel

12. How to set up a load test in 5 mins
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
