Class AssertTrueToAssertThat

  • 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 AssertTrueToAssertThat
extends org.openrewrite.java.JavaIsoRefactorVisitor
    This is a refactoring visitor that will convert JUnit-style assertTrue() to assertJ's assertThat().isTrue(). This visitor only supports the migration of the following JUnit 5 assertTrue() methods: 
         assertTrue(boolean condition) -> assertThat(condition).isTrue()
     assertTrue(boolean condition, String message) -> assertThat(condition).withFailMessage(message).isTrue();
     assertTrue(boolean condition, Supplier messageSupplier) -> assertThat(condition).withFailMessage(messageSupplier).isTrue();
    Note: There are three additional method signatures in JUnit that use a BooleanSupplier for the condition. Attempts to map these signatures into assertJ's model obfuscates the original assertion. It would be possible to use a shim method to support these method signatures, however, those shims would need to exist on each compilation unit or in a shared testing utilities library.
