Hey everyone! 
We added unit tests for 10 core piece packages that previously had no test coverage: data-mapper, math-helper, data-summarizer, csv, xml, crypto, date-helper, qrcode, file-helper, and image-helper.
97 tests covering happy paths and edge cases to catch regressions early.
We also published a new Testing Pieces docs page explaining how to write tests for your own pieces using Vitest and createMockActionContext.
