jest-styled-components 7.3.1

v7.3.1

on Node.js Yarn

Patch Changes

• c7b0e4e: Bug Fixes

  • Fix native toHaveStyleRule crash when element has no style prop (#225, #110)
  • Fix nested at-rules (@media inside @supports and vice versa) not being found by toHaveStyleRule (#245)
  • Fix getHTML() creating an empty ServerStyleSheet instead of reading from the global sheet (#401)
  • Fix selector matching with spaces around CSS combinators (> ul > li > a now matches correctly)
  • Fix invalid CSS causing cryptic parse errors — now shows the offending rule with surrounding context and a caret pointing at the exact error position (#147)
  • Fix nested React Native style arrays not flattening correctly

  Improvements

  • Add @container and @layer at-rule support for toHaveStyleRule and the snapshot serializer
  • Add opt-in CSS parse caching via import 'jest-styled-components/cache' for faster toHaveStyleRule in large test suites (#235)
  • Normalize whitespace in value comparisons so red !important, sidebar / inline-size, and rgb(0, 0, 0) match their stylis-formatted equivalents (skips quoted strings)
  • Clearer validation messages: "Property not found" instead of cryptic crash, human-readable options formatting, better negation wording
  • Export disableCSSCache from jest-styled-components/cache entry point
  • Add cache/index.d.ts for TypeScript users importing the cache entry point
  • Use Set for hash lookups (O(1) vs O(n) per lookup)
  • Serializer no longer mutates the parsed CSS AST
