Summary

  • Fixes Hamcrest to AssertJ unhandled cases (instanceOf, hasProperty and hasItem) #915 by adding three new recipes to handle previously unhandled Hamcrest matchers that were preventing full migration to AssertJ:

  • HamcrestHasPropertyToAssertJ: Converts hasProperty() to AssertJ's hasFieldOrProperty() or hasFieldOrPropertyWithValue()

  • HamcrestEveryItemToAssertJ: Converts everyItem() to hasOnlyElementsOfType() for instanceOf matchers or allSatisfy() for general matchers

  • HamcrestHasItemMatcherToAssertJ: Converts hasItem(Matcher) to hasAtLeastOneElementOfType() for instanceOf matchers or anySatisfy() for general matchers

All three recipes support optional reason arguments and properly handle import management.

Test plan

  • All 11 new tests pass (3 test classes with various scenarios)
  • All existing hamcrest migration tests continue to pass
  • Recipes are integrated into the MigrateHamcrestToAssertJ composite recipe

…em(Matcher)

Fixes #915 by adding three new recipes to handle previously unhandled Hamcrest matchers:
- HamcrestHasPropertyToAssertJ: converts hasProperty() to hasFieldOrProperty() or hasFieldOrPropertyWithValue()
- HamcrestEveryItemToAssertJ: converts everyItem() to hasOnlyElementsOfType() or allSatisfy()
- HamcrestHasItemMatcherToAssertJ: converts hasItem(Matcher) to hasAtLeastOneElementOfType() or anySatisfy()

Each recipe handles optional reason arguments and includes comprehensive tests.
