Any successful system or application must go through performance testing. It’s a non-functional software testing method. It helps determine a system’s responsiveness, scalability, speed, and stability under a specific workload. Performance testing is a vital step in ensuring system quality. However, it is, in most cases, seen as an afterthought. The objectives of a performance testing service include evaluating:
- System output
- Data transfer velocity
- Processing speed
- Memory utilization
- Maximum concurrent users
- Network bandwidth usage
- Command response times
- Workload efficiency and more
Benefits of Performance Testing
Performance testing provides various key benefits. It helps ensure that your system or application meets the expected service levels and offers a positive user experience. Applications or systems released publicly in the absence of testing could, in most cases, suffer from a damaged brand reputation. Performance test results will highlight enhancements you need to implement relative to scalability, stability, and speed before your system goes into production.
Applications’ adoption, success, and productivity depend directly on performance testing’s proper implementation. It is true that resolving production performance issues can be extremely expensive. However, the use of an endless optimization performance testing strategy is vital to the success of a productive overarching digital approach.
Tests Conducted
Various performance testing types are performed across the development lifecycle. This ensures that the system or application not only meets performance requirements but also fulfills user expectations. The main tests conducted include:
Stress Test
A stress test helps check the upper limits of your application. It involves testing the system under extreme loads. A stress test monitors how the application behaves under very intense loads as well as how it recovers when going back to normal usage. It ensures that KPIs, including responsive time and throughput, remain in the same condition before load spikes. Also, a stress test tool looks for things like:
- Data corruption
- Slowdowns
- Security problems
- Memory leaks
Load Test
A load test ensures that a system can manage to handle an expected volume of traffic or load limits as workload upsurge. It measures application performance when bombarded with certain amounts of simultaneous requests.
Sometimes, load tests are known as volume tests. Their main objective is to prove that an application can be able to handle its expected load limit with very minimal acceptance performance dilapidation.
Spike Test
Does your stress test include a sudden, high ramp-up in terms of virtual users? It’s known as a spike test. This type of test aims to see how your application behaves and performs in an unexpected fall and rise in the amount of users.
Spike tests in performance engineering help determine how much application performance deterioration takes place during an unexpected high load. Also, spike testing helps determine recovery time.
An application requires some time to stabilize between two successive user load spikes. The recovery time of a successful application needs to be as low as possible.
Scalability Test
A scalability test helps determine if the system is handling snowballing workloads effectively. Testers determine this by gradually increasing the user data or load volume while at the same time, monitoring resource usage and software performance. The workload may also stay at the same level while resources like memory and CPUs are changed.
Soak Test
A soak test is simply a stress test performed over an extended period to check the sustainability of the system. This type of performance testing is sometimes known as:
- Endurance testing
- Capacity testing
- Longevity testing
It involves testing an application to identify performance-related problems like response time and stability. The application is then evaluated, and the usage of resources is thoroughly checked to determine whether it could perform excellently under a massive load for a long period. It measures a system’s reaction and deeply analyzes its behavior and performance under sustained use.
Conclusion
You should find a top-rated performance testing service to help you evaluate how your application or system performs. The best service provider will help you identify bottlenecks via these test types, meaning your product will meet your business expectations and satisfy users.
