Püsivustest

Püsivustest, also known as persistence testing, is a software testing technique used to evaluate the reliability and stability of a system under prolonged stress. This type of testing is crucial for identifying potential issues that may not surface during normal usage or short-duration tests. Püsivustest typically involves running a system continuously for an extended period, often ranging from several hours to several days, while monitoring its performance and stability.

The primary goal of püsivustest is to uncover defects that may only manifest after prolonged operation, such as memory leaks, resource exhaustion, and software crashes. By simulating real-world usage conditions, this testing method helps ensure that the system can operate reliably over extended periods without requiring frequent restarts or interventions.

Püsivustest can be applied to various types of systems, including web applications, databases, and embedded systems. It is particularly important for systems that are expected to run continuously, such as server applications, network devices, and industrial control systems. The testing process often involves automated scripts that simulate user interactions and system workloads, allowing for continuous operation without manual intervention.

To conduct effective püsivustest, it is essential to define clear objectives and performance criteria. This includes setting thresholds for acceptable performance metrics, such as response time, throughput, and error rates. Monitoring tools and logging mechanisms are used to track system behavior and identify any anomalies or failures during the test.

In summary, püsivustest is a critical component of software quality assurance, helping to ensure that systems can operate reliably and efficiently over extended periods. By identifying and addressing potential issues early in the development process, this testing technique contributes to the overall robustness and stability of software systems.
