PSATest

PSATest is a software testing framework designed to automate performance and reliability testing for distributed systems. It provides a way to describe workload scenarios, execute them under controlled conditions, and collect standardized metrics for comparison across runs. The project emphasizes reproducibility, CI compatibility, and extensibility through plugins and adapters.

The core components include a test runner, a scenario language for defining targets, workloads, durations, and success criteria, and a metrics subsystem that aggregates latency, throughput, error rate, and resource usage. PSATest supports multiple protocol adapters (HTTP, gRPC, message queues) and can run tests locally or in distributed environments using container orchestration or SSH-based orchestration. Outputs are provided in machine-readable formats (JSON, CSV) and can be published to dashboards or external monitoring systems.

Typical workflows involve writing scenario definitions in human-readable files, configuring target endpoints and workload generators, executing tests via a command line or CI pipeline, and reviewing automated reports that highlight regressions, stability, and performance envelopes. The framework aims to be language-agnostic, enabling integration with applications written in various languages through adapters or client libraries.

PSATest is maintained as an open-source project with contributions from developers and users who value benchmark repeatability and transparent reporting. As with any testing tool, its effectiveness depends on carefully designed scenarios that reflect real-world usage patterns.
