Performance Testing Menggunakan JMeter

Summary

This presentation covers performance testing using JMeter for a website, focusing on load testing, stress testing, endurance testing, and speed testing. The team demonstrates how performance testing evaluates a system’s ability to handle user traffic, resource usage, and stability. Key steps include setting up test scenarios, using various metrics like response time and error rates, and testing system behavior under different loads. Through examples and results, the group illustrates how to assess and improve a website’s capacity to manage traffic, ensuring reliability and smooth user experience even under heavy load.

Q & A

What is performance testing in the context of software development?

Performance testing is the process of determining the speed and effectiveness of a software system, network, or hardware to evaluate its performance against a defined threshold.

Why is performance testing necessary for software applications?

Performance testing is crucial to measure the capabilities of a system, including attributes like resource usage, speed, scalability, stability, and reliability. It ensures that the application is user-friendly and accessible, even under heavy load.

What are the key aspects tested in performance testing?

Performance testing evaluates several aspects of a system, such as resource usage, speed, scalability, stability, and reliability, to ensure the system functions optimally under various conditions.

What does 'when' refer to in the context of performance testing?

The 'when' aspect refers to the timing of performance testing, which can be conducted at various stages of the software lifecycle, particularly when the system is stable and ready for functional testing.

Where can performance testing be applied?

Performance testing is used in software testing environments, specifically where hardware and software components need to be evaluated together to ensure they function well under load and meet the required specifications.

What is load testing, and how is it used in performance testing?

Load testing is used to assess how well a website or application can handle a specific volume of users. This test helps determine the load a website can sustain without causing issues in its performance, such as slow response times.

How is stress testing different from load testing?

Stress testing is designed to assess how an application handles extreme conditions, including very high traffic levels. Unlike load testing, which evaluates a system's performance under normal or expected traffic, stress testing pushes the system beyond its limits to check for weaknesses.

What is the purpose of spike testing, and how is it performed?

Spike testing involves suddenly increasing the number of users to test the system's capacity to handle abrupt surges in traffic. It is performed by simulating a sudden spike in the number of virtual users accessing the system.

What does endurance testing (or soak testing) measure?

Endurance testing measures a system's ability to handle continuous load over an extended period. The goal is to identify potential memory leaks or performance degradation during prolonged use under a steady load.

What were the results of the performance tests on the 'pegawai' website?

The performance tests on the 'pegawai' website showed that while it could handle a moderate load, the system struggled with large spikes in traffic. The error rate during testing was significant, indicating that the server was not sufficiently stable under heavy loads.
