Lark provides an adaptive testing platform that lets engineering teams author end‑to‑end test cases in plain English, automatically converting them into executable workflows. The AI‑driven engine updates UI selectors and API endpoints when the application changes, running tests on every commit and delivering results with integrated CI/CD, secure secret handling, and real‑time alerts.

Problem
Engineering teams often rely on code‑based test scripts that are fragile, require frequent maintenance after UI or API changes, and provide slow feedback in CI pipelines. This brittleness leads to missed regressions and increased manual effort to keep test suites up to date.
Solution
Lark offers an adaptive testing platform where test cases are authored in plain English, eliminating the need for low‑level scripting. The platform parses natural‑language workflows, generates executable test agents, and continuously adapts to UI or API modifications without breaking the test. Tests run automatically on every commit, pull request, or deployment, delivering results within minutes and integrating with popular CI/CD tools. Lark’s secure vault supplies credentials to transient test environments, and failures trigger instant alerts with logs and screenshots. A web‑based dashboard aggregates results, trends, and health metrics, enabling engineers to monitor quality across development stages.
Target Audience
The primary customers are software engineering and DevOps teams building web‑based SaaS applications that require reliable end‑to‑end testing of both front‑end interfaces and back‑end services.
