    • setIgnoreAllExpectedNullFields

      public void setIgnoreAllExpectedNullFields(boolean ignoreAllExpectedNullFields)

    • ignoreFields

      public void ignoreFields(String... fieldsToIgnore)
      Adds the given fields to the set of fields from the object under test to ignore in the recursive comparison.

      The fields are ignored by name, not by value.

      See RecursiveComparisonAssert#ignoringFields(String...) for examples.

      Parameters:
      fieldsToIgnore - the fields of the object under test to ignore in the comparison.
    • compareOnlyFields

      public void compareOnlyFields(String... fieldNamesToCompare)
      Adds the given fields and their subfields to the set of fields from the object under test to compare (no other fields will be compared).

      The fields are specified by name, not by value, you can specify person.name but not "Jack" as "Jack" is not a field value.

      Specifying a field will make all its subfields to be compared, for example specifying person will lead to compare person.name, person.address ... on the other hand if you specify person.name, person won't be compared but person.name will be.

      See RecursiveComparisonAssert#comparingOnlyFields(String...) for examples.

      Parameters:
      fieldNamesToCompare - the fields of the object under test to compare in the comparison.
    • ignoreFieldsMatchingRegexes

      public void ignoreFieldsMatchingRegexes(String... regexes)
      Allows to ignore in the recursive comparison the object under test fields matching the given regexes. The given regexes are added to the already registered ones.

      See RecursiveComparisonAssert#ignoringFieldsMatchingRegexes(String...) for examples.

      Parameters:
      regexes - regexes used to ignore fields in the comparison.
    • ignoreFieldsOfTypes

      public void ignoreFieldsOfTypes(Class<?>... types)
      Adds the given types to the list fields from the object under test types to ignore in the recursive comparison. The fields are ignored if their types exactly match one of the ignored types, if a field is a subtype of an ignored type it won't be ignored.

      Note that if some object under test fields are null, they are not ignored by this method as their type can't be evaluated.

      See RecursiveComparisonAssert#ignoringFieldsOfTypes(Class...) for examples.

      Parameters:
      types - the types of the object under test to ignore in the comparison.

      The fields must be specified from the root object, for example if Foo has a Bar field and both have an id field, one can register a comparator for Foo and Bar's id by calling:

       registerComparatorForFields(idComparator, "foo.id", "foo.bar.id")

      Comparators registered with this method have precedence over comparators registered with registerComparatorForType(Comparator, Class).

      Note that registering a Comparator for a given field will override the previously registered BiPredicate/Comparator (if any).

       registerEqualsForFields(idBiPredicate, "foo.id", "foo.bar.id")

      BiPredicates registered with this method have precedence over the ones registered with registerEqualsForType(BiPredicate, Class) or the comparators registered with registerComparatorForType(Comparator, Class).

      The fields must be specified from the root object, for example if Foo has a Bar field and both have an id field, one can register a message for Foo and Bar's id by calling:

       registerErrorMessageForFields("some message", "foo.id", "foo.bar.id")

      Messages registered with this method have precedence over the ones registered with registerErrorMessageForType(String, Class).

      In case of null as message the default error message will be used (See ComparisonDifference.DEFAULT_TEMPLATE).

      Parameters:
      message - the error message that will be thrown when comparison error occurred
      clazz - the type the error message should be used for
    • strictTypeChecking

      public void strictTypeChecking(boolean strictTypeChecking)
      Sets whether the recursive comparison will check that actual's type is compatible with expected's type (the same applies for each field). Compatible means that the expected's type is the same or a subclass of actual's type.
