      public static void verifyEqualsAndHashCode(Supplier<Object> supplier)
      An alias to the verifyEqualsAndHashCode(Object,Object) method, calling the provided Supplier<Object> for each. See that method description for details.
      Parameters:
      supplier - a supplier that will be called twice to provide the objects to be used in the test

    • verifyEqualsAndHashCode

      public static void verifyEqualsAndHashCode(Object instanceA, Object instanceB)
      Used to verify that the equals(Object) and hashCode() methods return values that meet with the standard contract for those methods. The two instances provided should be equivalent, but not the same instance.
      Parameters:
      instanceA - the first instance
      instanceB - the second instance

    • verifyToString

      public static void verifyToString(String expected, Supplier<Object> supplier)
      Used to verify that the toString() method of the object provided by the Supplier<Object> matches the expected String.
      Parameters:
      expected - the expected string
      supplier - a supplier that will be used to generate the object to be tested

    • verifyToString

      public static void verifyToString(org.hamcrest.Matcher<String> matcher, Supplier<Object> supplier)
      Used to verify that the toString() method of the object provided by the Supplier<Object> matches the given Matcher.
      Parameters:
      matcher - the Matcher for the generated string
      supplier - a supplier that will be used to generate the object to be tested

    • verifyToString
