#Testing Workflow

VSeed follows a strict test-driven development workflow. All test commands must be run from the project root directory.

#Test Categories

#1. Unit Tests

• Goal: Test individual utility functions and Pipeline node logic.
• Location: packages/vseed/tests/unit
• Run:

  pnpm --filter=@visactor/vseed run test:unit

#2. Integration Tests

• Goal: Test the complete chart generation flow (VSeed Spec -> VChart Spec).
• Mechanism: Data-driven. Automatically generates test cases by reading JSON files under packages/vseed/tests/integrations and compares snapshots.
• Run:

  pnpm --filter=@visactor/vseed run test:integration

#Core Workflow

#Step 1: Run Tests

Run relevant tests frequently during development to verify logic.

# Run all tests
pnpm --filter=@visactor/vseed run test

#Step 2: Handle Snapshot Changes

If your code changes cause the output Spec to change (e.g., fixing a bug or adding a feature):

1. Check the diff in the console output and confirm if the changes are expected.
2. If expected, run the update command:

   pnpm --filter=@visactor/vseed run test:update

#Step 3: Coverage Check

Before committing, it's recommended to check test coverage.

pnpm --filter=@visactor/vseed run test:coverage

#Notes

• Auto-generated: Integration test .test.ts files are generated by the g script — do not edit manually.
• Adding test cases: To add integration tests, simply add a new JSON config file to the appropriate category directory under packages/vseed/tests/integrations, then run pnpm run g.
