Class JUnitAssertNullToAssertThat

  • public class JUnitAssertNullToAssertThat
extends org.openrewrite.Recipe
    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();
