TestCaseAI analyzes your Python code, finds edge cases, and generates runnable pytest suites — then executes them and reports real coverage. No setup required.
Groq-powered pytest generation with happy paths, boundaries, and exceptions.
Automatic null, boundary, type-mismatch, and exception analysis per function.
Every job runs in its own isolated temp dir — tests actually run, once.
Real line coverage collected from the same test run, not estimated.
SSRF-guarded cloning, zip-slip protection, and size-limited uploads.
Copy or download runnable test modules with syntax highlighting.
Paste a snippet, drop a ZIP, or point at a public repo.
Functions are extracted and edge cases identified.
