This can be useful if actual's {@code equals} implementation does not suit you.970   * The recursive property/field comparison is <b>not</b> applied on fields having a custom {@code equals} implementation, i.e.971   * the overridden {@code equals} method will be used instead of a field by field comparison.972   * <p>973   * The recursive comparison handles cycles. By default {@code floats} are compared with a precision of 1.0E-6 and {@code doubles} with 1.0E-15.974   * <p>975   * You can specify a custom comparator per (nested) fields or type with respectively {@link #usingComparatorForFields(Comparator, String...) usingComparatorForFields(Comparator, String...)}976   * and {@link #usingComparatorForType(Comparator, Class)}.977   * <p>978   * The objects to compare can be of different types but must have the same properties/fields. For example if actual object has a name String field, it is expected the other object to also have one.979   * If an object has a field and a property with the same name, the property value will be used over the field.980   * <p>981   * Example:982   * <pre><code class='java'> public class Person {983   *   public String name;984   *   public double height;985   *   public Home home = new Home();986   *   public Person bestFriend;987   *   // constructor with name and height omitted for brevity988   * }989   *990   * public class Home {991   *   public Address address = new Address();992   * }993   *994   * public static class Address {995   *   public int number = 1;996   * }997   *998   * Person jack = new Person("Jack", 1.80);999   * jack.home.address.number = 123;1000   *1001   * Person jackClone = new Person("Jack", 1.80);1002   * jackClone.home.address.number = 123;1003   *1004   * // cycle are handled in comparison1005   * jack.bestFriend = jackClone;1006   * jackClone.bestFriend = jack;1007   *1008   * // will fail as equals compares object references1009   * assertThat(jack).isEqualTo(jackClone);1010   *1011   * // jack and jackClone are equals when doing a recursive field by field comparison1012   * assertThat(jack).isEqualToComparingFieldByFieldRecursively(jackClone);1013   *1014   * // any type/field can be compared with a a specific comparator.1015   * // let's change  jack's height a little bit1016   * jack.height = 1.81;1017   *1018   * // assertion fails because of the height difference1019   * // (the default precision comparison for double is 1.0E-15)1020   * assertThat(jack).isEqualToComparingFieldByFieldRecursively(jackClone);1021   *1022   * // this succeeds because we allow a 0.5 tolerance on double1023   * assertThat(jack).usingComparatorForType(new DoubleComparator(0.5), Double.class)1024   *                 .isEqualToComparingFieldByFieldRecursively(jackClone);1025   *1026   * // you can set a comparator on specific fields (nested fields are supported)1027   * assertThat(jack).usingComparatorForFields(new DoubleComparator(0.5), "height")1028   *                 .isEqualToComparingFieldByFieldRecursively(jackClone);</code></pre>1029   *1030   * @param other the object to compare {@code actual} to.1031   * @return {@code this} assertion object.1032   * @throws AssertionError if the actual object is {@code null}.1033   * @throws AssertionError if the actual and the given objects are not deeply equal property/field by property/field.1034   * @throws IntrospectionError if one property/field to compare can not be found.1035   */1036  @Deprecated1037  public SELF isEqualToComparingFieldByFieldRecursively(Object other) {1038    objects.assertIsEqualToComparingFieldByFieldRecursively(info, actual, other, comparatorByPropertyOrField,1039                                                            getComparatorsByType());1040    return myself;1041  }1042  /**1043   * Verifies that the object under test returns the given expected value from the given {@link Function},1044   * a typical usage is to pass a method reference to assert object's property.1045   * <p>1046   * Wrapping the given {@link Function} with {@link Assertions#from(Function)} makes the assertion more readable.1047   * <p>1048   * Example:1049   * <pre><code class="java"> // from is not mandatory but it makes the assertions more readable1050   * assertThat(frodo).returns("Frodo", from(TolkienCharacter::getName))1051   *                  .returns("Frodo", TolkienCharacter::getName) // no from :(1052   *                  .returns(HOBBIT, from(TolkienCharacter::getRace));</code></pre>1053   *1054   * @param expected the value the object under test method's call should return.1055   * @param from {@link Function} used to acquire the value to test from the object under test.
