Skalautuvuustestaus

Skalautuvuustestaus, or scalability testing in English, is a type of non-functional software testing. Its primary goal is to determine how well a system can scale up or down to handle an increasing or decreasing load. This testing is crucial for ensuring that an application or system can perform efficiently under anticipated user traffic and data volume.

The main objectives of scalability testing include verifying the system's ability to handle a growing number of users, processing more transactions concurrently, and managing increasing amounts of data without performance degradation. It helps identify bottlenecks and limitations within the system's architecture, such as insufficient hardware resources, inefficient code, or database constraints.

Scalability testing typically involves simulating various load conditions, from normal usage to peak loads. This can include load testing, stress testing, and endurance testing. Load testing measures performance under expected user loads, while stress testing pushes the system beyond its normal operating limits to identify its breaking point. Endurance testing, also known as soak testing, checks for performance issues that may arise over extended periods of high usage, such as memory leaks.

By conducting scalability testing, organizations can gain confidence that their systems will remain responsive and stable as their user base and data grow. This proactive approach helps prevent performance issues that could lead to a poor user experience, lost revenue, and damage to reputation. It informs decisions about infrastructure upgrades, resource allocation, and system optimization.
