/workflows - Repository Workflows

Common developer workflows and commands for working in leanSpec.

Running Specific Tests

# Single test file
just test tests/node/networking/transport/test_peer_id.py -v

# Single test class or method
just test -k "TestDiscoveryTransport::test_start" -v

# With print output visible
just test -s -k "test_name"

Resolving Type Errors

The project uses two type checkers. Run them separately to isolate issues:

# Full type check (ty — the primary checker used in CI)
just typecheck

# Lint check (ruff — catches style and import issues)
just lint

Common type error patterns:

• invalid-assignment — Wrong type assigned; check if a domain type (RequestId, PeerId) is expected instead of raw bytes
• invalid-argument-type — Function argument type mismatch; verify the function signature
• union-attr — Accessing attribute on a possibly-None value; add an assert is not None guard

Inspecting Coverage

After running tests, coverage reports are generated:

# View coverage in terminal
just test-cov

# Open HTML report
open htmlcov/index.html

Running Interop Tests

Interop tests are excluded from the default test run. Run them explicitly:

just interop

Spell Check Failures

# Run spell check
just spellcheck

# Add legitimate words to the ignore list
echo "newword" >> .codespell-ignore-words.txt

Markdown Formatting

# Check markdown formatting (docs only)
just mdformat

Common Pitfalls

• Tests pass locally but CI fails: CI runs checks across Python 3.12, 3.13, and 3.14. Ensure no version-specific syntax is used.
• ruff format changes after ruff check --fix: Always run format after fix — the fixer doesn't guarantee formatting compliance.
• Import ordering issues: Run just fix to auto-sort imports.
