What Are the Different Types of Performance Testing?

Performance testing is a software testing process used to test a software application's speed, response time, stability, reliability, scalability, and resource utilization in a specific workload. There are various types of tests, and the performance test is one of the most important types of tests, which ensures that our software runs smoothly under various load conditions.

Benchmark Testing

Essentially, benchmarks test the performance of our system in terms of stability, sensitivity, and responsiveness under various load conditions. Essentially, benchmarks determine how fast a system is running. Some of the issues identified through such tests are runtime bloat, optimization issues related to speed, latency, throughput, poor response time, load balancing issues, and other bandwidth issues, if any talk. This type of performance testing is used to determine an application's ability to handle an increasing number of workloads and processing.

Load Testing

A load test is a type of performance test that helps determine the performance of an application with an increasing workload until it reaches thresholds. The purpose of a load test is to evaluate the performance of applications as the number of users increases. Load testing is pushing a software, system, or device to measure how the software responds to an expected load. Performance testing or load testing is an essential type of non-functional testing. It includes testing a software or application to determine the performance of a current system.

Stress Testing

A stress test tests a system's performance under extreme pressure, an unexpected load. A stress test is a negative test where we load software with many concurrent users/processes that the system's hardware resources cannot handle.

Peak Testing

A peak test is a stress test that evaluates software performance when workloads increase significantly and many times over. The peak test, another subset of stress tests, evaluates the performance of a system in the face of a sudden and significant increase in simulated end users. Peak testing tests the performance of a system during abrupt load changes with a sudden increase or decrease, also known as spikes.

Fatigue Testing

Unlike stress tests, stress tests, also known as fatigue tests, are designed to measure the performance of a system beyond the parameters of normal operating conditions. An endurance test, also known as an absorption test or capacitance test, tests the ability of systems to operate under constant load for an extended period. Endurance testing is performed by applying various loads to the application under test over an extended period to verify compliance with the performance requirements associated with the production loads and the life of those loads. The endurance test evaluates the performance of a system under load over time.

Before launch, the software system must be tested for speed, stability, and scalability under various load conditions. The development team can tweak the software based on the test reports to improve performance. Checking for errors does not give a clear idea of??how the program will work under load. It's tempting to run the test at full load to find any performance issues.

If there's a lesson to be learned from these four types of load tests, it's this: performance engineering teams need to think meaningfully about the purpose of each test and their expectations of the system under test.

Scalability Testing

The scalability test tests the software's ability to scale up/down or down/up when it is subject to changes in performance attributes (or metrics). A scalability test is a type of non-functional test that tests a software application performed by a Software Testing Company to determine its ability to grow in terms of any of its non-functional capabilities such as supported user load, number of transactions, amount of data, etc. Scalability tests measure performance based on the ability of software to increase or decrease performance measurement attributes.
