Class JUnitAssertNotEqualsToAssertThat

  • public class JUnitAssertNotEqualsToAssertThat
extends org.openrewrite.Recipe
    This is a refactoring visitor that will convert JUnit-style assertNotEquals() to assertJ's assertThat().isNotEqualTo().

    This visitor has to convert a surprisingly large number (93 methods) of JUnit's assertEquals to assertThat(). 

     Two parameter variants:
 
    
 assertNotEquals(expected,actual) == assertThat(actual).isNotEqualTo(expected)
 
    
 Three parameter variant where the third argument is a String:
 
    
 assertNotEquals(expected, actual, "message") == assertThat(actual).as("message").isNotEqualTo(expected)
 
    
 Three parameter variant where the third argument is a String Supplier (there is no overloaded "as" method that takes a supplier):
 
    
 assertNotEquals(expected, actual, "message") == assertThat(actual).withFailMessage("message").isNotEqualTo(expected)
 
    
 Three parameter variant where args are all floating point numbers.
 
    
 assertEquals(expected, actual, delta) == assertThat(actual).isCloseTo(expected, within(delta));
 
    
 Four parameter variant when comparing floating point numbers with a delta and a message:
 
    
 assertEquals(expected, actual, delta, "message") == assertThat(actual).withFailureMessage("message").isCloseTo(expected, within(delta));
