Test Automation Modernization for SDETs

AI-driven test suite refactoring and modernization

$5 free credits • Pay-as-you-go • Works with your existing tools

The problems you face today

Legacy test suites are brittle and hard to maintain
AI analyzes patterns and generates modernization plans
Framework migrations risk breaking existing test coverage
Generate migration plans with test equivalence validation
Test coverage gaps are hard to identify and fix
AI maps code coverage and suggests targeted test additions

How it works

1

Analyze existing test architecture

2

Generate modernization roadmap

3

Plan incremental migration steps

4

Validate test coverage equivalence

Key capabilities

Test pattern analysis
Framework migration planning
Coverage gap detection

Technical implementation

Intelligent File Discovery

Hierarchical folder selection, pattern filtering, and AI relevance assessment

  • Root folder selection based on task
  • Targeted regex pattern groups
  • LLM analyzes actual file contents
  • Automatic dependency detection
  • Files organized into XML for LLM consumption

Multi-Model Planning

Generate multiple implementation approaches using different AI models, then synthesize the best solution

  • OpenAI GPT‑5 family (GPT‑5 and GPT‑5 Thinking/Pro), historical o‑series (e.g., o3 variants); Anthropic Claude Sonnet 4 and Opus 4.1; Google Gemini 2.5 Pro - availability and features vary by plan and endpoint (ChatGPT vs API).
  • AI architect merges best insights
  • Your guidance shapes the merge

Use official vendor docs to confirm features like streaming, function calling, and background mode for each model.
