Functional and Performance Testing.
Better Together.
Go beyond testing application functionality and performance separately. StresStimulus connects automated functional testing with scalable load testing to validate complex business workflows under realistic conditions.
Reuse Functional Tests for Load Testing
Automatically convert Playwright functional tests into protocol-based load tests, reducing scripting effort and simplifying maintenance as applications evolve.
Validate Functionality Under Load
Execute Playwright browser users alongside protocol virtual users to verify that critical business workflows continue working correctly while the application is under load.
Measure Real-Browser Performance
Run browser-based load tests to capture real-user experience metrics, with support for distributed execution across multiple load generators.
Turn Performance Data Into Insights
StresStimulus goes beyond traditional load test reports, combining performance metrics, failed assertions and validations, and AI-assisted diagnostics to help you understand what changed, where performance degraded, and what may be causing the problem.
Regression Detection
Automatically compare test runs against a baseline and identify meaningful performance degradation.
Trend Diagnostics
Track key performance metrics across test runs to identify patterns and changes over time.
Performance Diagnostics
Identify the transactions and requests contributing most to performance degradation and correlate test results with server metrics and application telemetry to help pinpoint the cause.
Scalability Diagnostics
Compare tests at different load levels to understand how application performance changes as demand increases.
AI-Assisted Diagnostics
Generate an AI-ready summary of your test results that can be shared with your preferred LLM to investigate performance issues, summarize findings, and explore your results using natural language.
Bring Continuous Quality
Into Your CI/CD Pipeline
Integrate automated functional and performance testing into your CI/CD workflows to continuously validate software quality. Automatically execute tests to detect functional failures, performance regressions, and scalability issues. Generate machine-readable reports and notify your team when quality issues are detected.
Automate Performance Tests
Run existing StresStimulus tests unattended from GitHub Actions, Azure DevOps, Jenkins, GitLab, and other CI/CD workflows.
Enforce Performance Criteria
Use pass/fail rules and regression detection to make performance requirements part of your release process.
Generate CI-Friendly Reports
Export test results in formats designed for automated pipelines, including JUnit, NUnit, and JSON.
Notify Your Team
Send test results and performance alerts through email, Slack, Microsoft Teams, webhooks, and other integrations.
