Simplify AssertJ assertions on instanceof expressions
Recipe ID
org.openrewrite.java.testing.assertj.SimplifyAssertJInstanceOfAssertionArtifact
org.openrewrite.recipe:rewrite-testing-frameworksReplace assertThat(x instanceof Type).isTrue() with the dedicated assertThat(x).isInstanceOf(Type.class), and the negated and isFalse() variants with isNotInstanceOf, so failures describe the actual type rather than just expected true but was false.
