Recipe IDorg.openrewrite.java.testing.assertj.SimplifyStreamMapToExtracting
Artifactorg.openrewrite.recipe:rewrite-testing-frameworks

Simplifies AssertJ assertions that use stream().map() to extract values from a collection by using the dedicated extracting() method instead. This makes the assertion more readable and leverages AssertJ's built-in extraction capabilities.
