Testing

Testing

The CLI can run its test suite directly.

Why these tests matter

The test suite is designed to validate the real tool behavior:

• fetch real market data
• compute real indicator columns
• validate constraints (e.g. RSI range)
• validate writers/readers across formats

Run tests

All tests:

indicators --test

Specific suite:

indicators --test --test-suite correctness

Suites

• correctness: validates indicator computations are sane and within expected constraints
• integration: end-to-end runs (fetch → compute → write)
• formats: validates writing/reading across formats
• batch: validates multi-ticker behavior

Notes

• Tests use real Yahoo Finance data (not mocked). This increases realism but can introduce intermittent failures due to upstream availability.
• If you need deterministic performance benchmarking, use cached profiling mode (see Reproducibility).
