Description

Summary Increase coverage and give newcomers a gentle intro to the Jest setup by testing a small, pure utility function.

Where

  • apps/studio/src/shared/lib (pick a pure function: formatter, geometry helper, id generator).
  • Test config: jest.config.ts at repo root.

Steps

  1. Branch: git checkout -b test/shared-lib-util.
  2. Choose a small pure function with no side effects.
  3. Create a colocated *.test.ts; cover the happy path plus 1–2 edge cases.
  4. Run yarn test and confirm it passes.
  5. Commit test: add unit tests for <function> and open a PR.

Acceptance criteria

  • New test file passes under yarn test.
  • At least 3 assertions covering normal + edge cases.

Good first issue — comment here if you'd like to take it.

Contributor guide

Research direction
Pick a pure function from apps/studio/src/shared/lib and write Jest tests covering happy path and edge cases. 1. Check the directory for a small pure function (e.g., a formatter or helper). 2. Create a colocated *.test.ts file. 3. Implement at least 3 assertions: normal input, one edge case (e.g., empty, null), and another edge case. 4. Run `yarn test` to verify. 5. Commit and open a PR.
