Method Details
- checkEqualsAndHashCode
  
  public static <T> void checkEqualsAndHashCode(T original, EqualsHashCodeTestUtils.CopyFunction<T> copyFunction)
  
  Perform common equality and hashCode checks on the input object
  
  Parameters:
  
  original - the object under test
  
  copyFunction - a function that creates a deep copy of the input object
- checkEqualsAndHashCode
  
  public static <T> void checkEqualsAndHashCode(T original, EqualsHashCodeTestUtils.CopyFunction<T> copyFunction, EqualsHashCodeTestUtils.MutateFunction<T> mutationFunction)
  
  Perform common equality and hashCode checks on the input object
  
  Parameters:
  
  original - the object under test
  
  copyFunction - a function that creates a deep copy of the input object
  
  mutationFunction - a function that creates a copy of the input object that is different from the input in one aspect. The output of this call is used to check that it is not equal() to the input object
