Generate comprehensive unit, integration, and e2e tests from source code. Reasoning models understand edge cases, boundary conditions, and error paths.
Analyze code for potential bugs, race conditions, and security vulnerabilities. Large context handles full codebases for cross-module analysis.
Generate realistic test data, mock objects, and API fixtures. JSON mode produces structured data compatible with testing frameworks.
Write Selenium, Playwright, and Cypress scripts. Function calling enables test orchestration and CI/CD pipeline integration.
