This guide provides a detailed overview of how to perform performance tests (load tests) with NeoLoad using a simple example application JPetStore. Each step is designed to ensure accurate, reliable and scalable testing processes.
Tools
We use Tricentis Neoload and JPetStore as sample applications.
- Tricentis Neoload is an established performance testing tool for APIs, microservices and E2E testing. You can find out more at tricentis.com/en/platform/performancetests-neoload.
- JPetStore is a simple online store demo application based on the Aspectran framework and is available at jpetstore.aspectran.com.
1. record realistic test scripts
The performance test process starts with recording user interactions within the JPetStore application. This is done in order to create realistic test scripts that reflect actual user behavior as accurately as possible.
2. determine how to handle dynamic variables
An important aspect of scripting is the correct handling of dynamic variables. These variables, such as session IDs, are identified and configured accordingly. This ensures that the scripts work correctly even if data changes frequently or is session-specific.
3. simulate real user behavior
To validate the results of the tests, validation steps are added. These steps check whether the server provides the correct answers during the test execution. Think times are also configured. These simulate the natural pauses that users make when navigating through an application and thus contribute to a realistic test scenario.
4. define performance targets
Service Level Agreements (SLAs) are defined to monitor performance. These SLAs specify which key performance indicators (KPIs) must be met. This ensures that the application meets the required performance standards and provides a good user experience.
5. perform load tests
Finally, test scenarios are designed to evaluate the application performance under different load conditions. These scenarios are then executed and the results are analyzed. The goal is to identify potential bottlenecks and areas where the application's performance can be optimized.
Key Takeaways
This guide has shown you the basic steps for performance testing with NeoLoad using the JPetStore application as an example.
You have learned
- How to record user actions,
- handle variable data,
- create realistic test scenarios
- and define performance targets.
In practice, however, performance tests are often much more complex.
Factors such as the architecture of the application to be tested, the integration of different systems, the distribution of the load across several servers and the interpretation of the results require in-depth specialist knowledge and experience.
We are happy to help you.
To ensure that your complex business applications function reliably even under high load and provide an optimal user experience , it is advisable to work with a specialized company.
