Class AssertNullToAssertThat

  • All Implemented Interfaces:
    org.openrewrite.java.JavaSourceVisitor<org.openrewrite.java.tree.J>, org.openrewrite.RefactorVisitor<org.openrewrite.java.tree.J>, org.openrewrite.SourceVisitor<org.openrewrite.java.tree.J>
    public class AssertNullToAssertThat
extends org.openrewrite.java.JavaIsoRefactorVisitor
    This is a refactoring visitor that will convert JUnit-style assertNull() to assertJ's assertThat().isNull(). This visitor only supports the migration of the following JUnit 5 assertNull() methods: 
         assertNull(Object actual) -> assertThat(condition).isNull()
     assertNull(Object actual, String message) -> assertThat(condition).as(message).isNull();
     assertNull(Object actual, Supplier messageSupplier) -> assertThat(condition).withFailMessage(messageSupplier).isNull();
