      • as

        public AtomicReferenceArrayAssert<T> as​(Description description)
        Description copied from interface: Descriptable
        Sets the description of the assertion that is going to be called after.

        You must set it before calling the assertion otherwise it is ignored as the failing assertion breaks the chained call by throwing an AssertionError.

        This overloaded version of "describedAs" offers more flexibility than the one taking a String by allowing users to pass their own implementation of a description. For example, a description that creates its value lazily, only when an assertion failure occurs.

        Specified by:
        as in interface Descriptable<T>
        Parameters:
        description - the new description to set.
        Returns:
        this object.
        See Also:
        Descriptable.describedAs(Description)

      • as

        public AtomicReferenceArrayAssert<T> as​(String description,
                                        Object... args)
        Description copied from interface: Descriptable
        Sets the description of the assertion that is going to be called after.

        You must set it before calling the assertion otherwise it is ignored as the failing assertion breaks the chained call by throwing an AssertionError.

        The description follows String.format(String, Object...) syntax.

        Example : 

         try {
   // set a bad age to Mr Frodo which is really 33 years old.
   frodo.setAge(50);
   // specify a test description (call as() before the assertion !), it supports String format syntax.
   assertThat(frodo.getAge()).as("check %s's age", frodo.getName()).isEqualTo(33);
 } catch (AssertionError e) {
   assertThat(e).hasMessage("[check Frodo's age] expected:<[33]> but was:<[50]>");
 }
        Specified by:
        as in interface Descriptable<T>
        Parameters:
        description - the new description to set.
        args - optional parameter if description is a format String.
        Returns:
        this object.

      • containsAll

        public AtomicReferenceArrayAssert<T> containsAll​(Iterable<? extends T> iterable)
        Verifies that the actual AtomicReferenceArray contains all the elements of given Iterable, in any order.

        Example : 

         AtomicReferenceArray<String> abc = new AtomicReferenceArray<>(new String[]{"a", "b", "c"});

 // assertion will pass
 assertThat(abc).containsAll(Arrays.asList("b", "c"));

 // assertions will fail
 assertThat(abc).containsAll(Arrays.asList("d"));
 assertThat(abc).containsAll(Arrays.asList("a", "b", "c", "d"));
        Specified by:
        containsAll in interface ObjectEnumerableAssert<AtomicReferenceArrayAssert<T>,​T>
        Parameters:
        iterable - the given Iterable we will get elements from.
        Returns:
        this assertion object.
        Throws:
        NullPointerException - if the given argument is null.
        AssertionError - if the actual AtomicReferenceArray is null.
        AssertionError - if the actual AtomicReferenceArray does not contain all the elements of given Iterable.

      • usingElementComparator

        public AtomicReferenceArrayAssert<T> usingElementComparator​(Comparator<? super T> elementComparator)
        Use given custom comparator instead of relying on actual element type equals method to compare AtomicReferenceArray elements for incoming assertion checks.

        Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default comparison strategy.

        Examples : 

         // compares invoices by payee
 assertThat(invoiceArray).usingComparator(invoicePayeeComparator).isEqualTo(expectedinvoiceArray).

 // compares invoices by date, doesNotHaveDuplicates and contains both use the given invoice date comparator
 assertThat(invoiceArray).usingComparator(invoiceDateComparator).doesNotHaveDuplicates().contains(may2010Invoice)

 // as assertThat(invoiceArray) creates a new assertion, it falls back to standard comparison strategy
 // based on Invoice's equal method to compare invoiceArray elements to lowestInvoice.
 assertThat(invoiceArray).contains(lowestInvoice).

 // standard comparison : the fellowshipOfTheRing includes Gandalf but not Sauron (believe me) ...
 assertThat(fellowshipOfTheRing).contains(gandalf)
                                .doesNotContain(sauron);

 // ... but if we compare only races, Sauron is in fellowshipOfTheRing because he's a Maia like Gandalf.
 assertThat(fellowshipOfTheRing).usingElementComparator(raceComparator)
                                .contains(sauron);
        Specified by:
        usingElementComparator in interface EnumerableAssert<AtomicReferenceArrayAssert<T>,​T>
        Parameters:
        elementComparator - the comparator to use for incoming assertion checks.
        Returns:
        this assertion object.
        Throws:
        NullPointerException - if the given comparator is null.

      • usingFieldByFieldElementComparator

        public AtomicReferenceArrayAssert<T> usingFieldByFieldElementComparator()
        Use field/property by field/property comparison (including inherited fields/properties) instead of relying on actual type A equals method to compare AtomicReferenceArray elements for incoming assertion checks. Private fields are included but this can be disabled using Assertions.setAllowExtractingPrivateFields(boolean).

        This can be handy if equals method of the objects to compare does not suit you.

        You can specify a custom comparator per name or type of element field with usingComparatorForElementFieldsWithNames(Comparator, String...) and usingComparatorForElementFieldsWithType(Comparator, Class).

        Note that the comparison is not recursive, if one of the fields/properties is an Object, it will be compared to the other field/property using its equals method.

        Example: 
         TolkienCharacter frodo = new TolkienCharacter("Frodo", 33, HOBBIT);
 TolkienCharacter frodoClone = new TolkienCharacter("Frodo", 33, HOBBIT);

 // Fail if equals has not been overridden in TolkienCharacter as equals default implementation only compares references

      • usingRecursiveFieldByFieldElementComparator

        public AtomicReferenceArrayAssert<T> usingRecursiveFieldByFieldElementComparator()
        Use a recursive field/property by field/property comparison (including inherited fields/properties) instead of relying on actual type A equals method to compare AtomicReferenceArray elements for incoming assertion checks. This can be useful if actual's equals implementation does not suit you.

        The recursive property/field comparison is not applied on fields having a custom equals implementation, i.e. the overridden equals method will be used instead of a field/property by field/property comparison.

        You can specify a custom comparator per (nested) name or type of element field with usingComparatorForElementFieldsWithNames and usingComparatorForElementFieldsWithType.

        The recursive comparison handles cycles.

        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, the other object must also have one.

        If an object has a field and a property with the same name, the property value will be used over the field.

        Example: 

         TolkienCharacter frodo = new TolkienCharacter("Frodo", 33, HOBBIT);
 TolkienCharacter pippin = new TolkienCharacter("Pippin", 28, HOBBIT);
 frodo.setFriend(pippin);
 pippin.setFriend(frodo);

 TolkienCharacter frodoClone = new TolkienCharacter("Frodo", 33, HOBBIT);
 TolkienCharacter pippinClone = new TolkienCharacter("Pippin", 28, HOBBIT);
 frodoClone.setFriend(pippinClone);
 pippinClone.setFriend(frodoClone);

 AtomicReferenceArray<TolkienCharacter> hobbits = new AtomicReferenceArray<>(new TolkienCharacter[] {frodo, pippin});

 // fails if equals has not been overridden in TolkienCharacter as it would compares object references
 assertThat(hobbits).contains(frodoClone, pippinClone);

 // frodo/frodoClone and pippin/pippinClone are equals when doing a recursive property/field by property/field comparison
 assertThat(hobbits).usingRecursiveFieldByFieldElementComparator()
                    .contains(frodoClone, pippinClone);
        Returns:
        this assertion object.

      • usingElementComparatorOnFields

        public AtomicReferenceArrayAssert<T> usingElementComparatorOnFields​(String... fields)
        Use field/property by field/property comparison on the given fields/properties only (including inherited fields/properties) instead of relying on actual type A equals method to compare AtomicReferenceArray elements for incoming assertion checks. Private fields are included but this can be disabled using Assertions.setAllowExtractingPrivateFields(boolean).

 TolkienCharacter sam = new TolkienCharacter("Sam", 38, HOBBIT);

 // frodo and sam both are hobbits, so they are equals when comparing only race

      • usingElementComparatorIgnoringFields

        public AtomicReferenceArrayAssert<T> usingElementComparatorIgnoringFields​(String... fields)
        Use field/property by field/property on all fields/properties except the given ones (including inherited fields/properties) instead of relying on actual type A equals method to compare AtomicReferenceArray elements for incoming assertion checks.

        Extract the values of given fields/properties from the array's elements under test into a new array composed of Tuple (a simple data structure), this new array becoming the array under test.

        It allows you to test fields/properties of the array's elements instead of testing the elements themselves, it can be sometimes much less work !

        The Tuple data corresponds to the extracted values of the given fields/properties, for instance if you ask to extract "id", "name" and "email" then each Tuple data will be composed of id, name and email extracted from the element of the initial array (the Tuple's data order is the same as the given fields/properties order).

        Let's take an example to make things clearer :

      • extracting

        public <U,​EXCEPTION extends Exception> ObjectArrayAssert<U> extracting​(ThrowingExtractor<? super T,​U,​EXCEPTION> extractor)
        Extract the values from the array's elements by applying an extracting function (which might throw an exception) on them. The returned array becomes a new object under test.

        Any checked exception raised in the extractor is rethrown wrapped in a RuntimeException.

        It allows to test values from the elements in safer way than by using extracting(String), as it doesn't utilize introspection.

        Let's take a look an example: 

         // Build a list of TolkienCharacter, a TolkienCharacter has a name, and age and a Race (a specific class)
 // they can be public field or properties, both can be extracted.
 AtomicReferenceArray<TolkienCharacter> fellowshipOfTheRing = new AtomicReferenceArray<>(new TolkienCharacter[]{
   new TolkienCharacter("Frodo", 33, HOBBIT),
   new TolkienCharacter("Sam", 38, HOBBIT),
   new TolkienCharacter("Gandalf", 2020, MAIA),
   new TolkienCharacter("Legolas", 1000, ELF),
   new TolkienCharacter("Pippin", 28, HOBBIT),
   new TolkienCharacter("Gimli", 139, DWARF),
   new TolkienCharacter("Aragorn", 87, MAN,
   new TolkienCharacter("Boromir", 37, MAN)
 };

 assertThat(fellowshipOfTheRing).extracting(input -> {
   if (input.getAge() < 20) {
     throw new Exception("age < 20");
   }
   return input.getName();
 }).contains("Frodo");
        Note that the order of extracted property/field values is consistent with the iteration order of the Iterable under test, for example if it's a HashSet, you won't be able to make any assumptions on the extracted values order.
        Type Parameters:
        U - the extracted values type
        EXCEPTION - the exception type
        Parameters:
        extractor - the object transforming input object to desired one
        Returns:
        a new assertion object whose object under test is the list of values extracted

      • flatExtracting

        public <U,​C extends Collection<U>> ObjectArrayAssert<U> flatExtracting​(Function<? super T,​C> extractor)
        Extract the Iterable values from the array's elements by applying an Iterable extracting function on them and concatenating the result lists into an array which becomes the new object under test.

        It allows testing the results of extracting values that are represented by Iterables.

        For example: 

         CartoonCharacter bart = new CartoonCharacter("Bart Simpson");
 CartoonCharacter lisa = new CartoonCharacter("Lisa Simpson");
 CartoonCharacter maggie = new CartoonCharacter("Maggie Simpson");
 CartoonCharacter homer = new CartoonCharacter("Homer Simpson");
 homer.addChildren(bart, lisa, maggie);

 fred.getChildren().add(pebbles);

 Function<CartoonCharacter, List<CartoonCharacter>> childrenOf = new Function<CartoonCharacter, List<CartoonCharacter>>() {
    @Override
    public List<CartoonChildren> extract(CartoonCharacter input) {
        return input.getChildren();
    }
 }

 AtomicReferenceArray<CartoonCharacter> parents = new AtomicReferenceArray<>(new CartoonCharacter[]{ homer, fred });
 // check children
 assertThat(parents).flatExtracting(childrenOf)
                    .containsOnly(bart, lisa, maggie, pebbles);
        The order of extracted values is consisted with both the order of the collection itself, as well as the extracted collections.
        Type Parameters:
        U - the type of elements to extract.
        C - the type of collection to flat/extract.
        Parameters:

      • extractingResultOf

        public ObjectArrayAssert<Object> extractingResultOf​(String method)
        Extract the result of given method invocation from the array's elements under test into a new array, this new array becoming the array under test.

        It allows you to test a method results of the array's elements instead of testing the elements themselves, which can be much less work!

        It is especially useful for classes that does not conform to the Java Bean's getter specification (i.e. public String toString() or public String status() instead of public String getStatus()).

        Let's take an example to make things clearer : 

         // Build a array of WesterosHouse, a WesterosHouse has a method: public String sayTheWords()
 AtomicReferenceArray<WesterosHouse> greatHousesOfWesteros = new AtomicReferenceArray<>(new WesterosHouse[]{
     new WesterosHouse("Stark", "Winter is Coming"),
     new WesterosHouse("Lannister", "Hear Me Roar!"),

     new WesterosHouse("Baratheon", "Our is the Fury"),
     new WesterosHouse("Martell", "Unbowed, Unbent, Unbroken"),
     new WesterosHouse("Tyrell", "Growing Strong") });

 // let's verify the words of the great houses of Westeros:

                                  .contains("Winter is Coming", "We Do Not Sow", "Hear Me Roar")
                                  .doesNotContain("Lannisters always pay their debts");

        Following requirements have to be met to extract method results:

        • method has to be public,
        • method cannot accept any arguments,
        • method cannot return void.

        Note that the order of extracted values is consistent with the order of the array under test.

        Parameters:
        method - the name of the method which result is to be extracted from the array under test
        Returns:
        a new assertion object whose object under test is the array of extracted values.
        Throws:
        IllegalArgumentException - if no method exists with the given name, or method is not public, or method does return void, or method accepts arguments.

      • inHexadecimal

        public AtomicReferenceArrayAssert<T> inHexadecimal()
        Enable hexadecimal object representation of Iterable elements instead of standard java representation in error messages.

        It can be useful to better understand what the error was with a more meaningful error message.

        Example 

        
 AtomicReferenceArray<Byte> bytes = new AtomicReferenceArray<>(new Byte[]{ 0x10, 0x20 });
 assertThat(bytes).inHexadecimal().contains(new Byte[] { 0x30 });
        With standard error message: 
         Expecting:
  <[16, 32]>
 to contain:
  <[48]>
 but could not find:
  <[48]>
        With Hexadecimal error message: 
         Expecting:
  <[0x10, 0x20]>
 to contain:
  <[0x30]>
 but could not find:
  <[0x30]>
        Overrides:
        inHexadecimal in class AbstractAssert<AtomicReferenceArrayAssert<T>,​AtomicReferenceArray<T>>
        Returns:
        this assertion object.

      • filteredOn

        public AtomicReferenceArrayAssert<T> filteredOn​(String propertyOrFieldName,
                                                Object expectedValue)
        Filter the array under test keeping only elements having a property or field equal to expectedValue, the property/field is specified by propertyOrFieldName parameter.

        The filter first tries to get the value from a property (named propertyOrFieldName), if no such property exists it tries to read the value from a field. Reading private fields is supported by default, this can be globally disabled by calling Assertions.setAllowExtractingPrivateFields(false).

        When reading nested property/field, if an intermediate value is null the whole nested property/field is considered to be null, thus reading "address.street.name" value will return null if "street" value is null.

        As an example, let's check all employees 800 years old (yes, special employees): 

         Employee yoda   = new Employee(1L, new Name("Yoda"), 800);
 Employee obiwan = new Employee(2L, new Name("Obiwan"), 800);
 Employee luke   = new Employee(3L, new Name("Luke", "Skywalker"), 26);
 Employee noname = new Employee(4L, null, 50);

 AtomicReferenceArray<Employee> employees = new AtomicReferenceArray<>(new Employee[]{ yoda, luke, obiwan, noname });

 assertThat(employees).filteredOn("age", 800)
                      .containsOnly(yoda, obiwan);
        Nested properties/fields are supported: 
         // Name is bean class with 'first' and 'last' String properties

 // name is null for noname => it does not match the filter on "name.first"
 assertThat(employees).filteredOn("name.first", "Luke")
                      .containsOnly(luke);

 assertThat(employees).filteredOn("name.last", "Vader")
                      .isEmpty();

        If you want to filter on null value, use filteredOnNull(String) as Java will resolve the call to filteredOn(String, FilterOperator) instead of this method.

        An IntrospectionError is thrown if the given propertyOrFieldName can't be found in one of the array elements.

        You can chain filters: 

         // fellowshipOfTheRing is an array of TolkienCharacter having race and name fields
 // 'not' filter is statically imported from Assertions.not

 assertThat(fellowshipOfTheRing).filteredOn("race.name", "Man")
                                .filteredOn("name", not("Boromir"))
                                .containsOnly(aragorn);
        If you need more complex filter, use filteredOn(Condition) and provide a Condition to specify the filter to apply.
        Parameters:
        propertyOrFieldName - the name of the property or field to read
        expectedValue - the value to compare element's property or field with
        Returns:
        a new assertion object with the filtered array under test
        Throws:
        IllegalArgumentException - if the given propertyOrFieldName is null or empty.
        IntrospectionError - if the given propertyOrFieldName can't be found in one of the array elements.

      • filteredOnNull

        public AtomicReferenceArrayAssert<T> filteredOnNull​(String propertyOrFieldName)

        Filter the array under test keeping only elements having a property or field matching the filter expressed with the FilterOperator, the property/field is specified by propertyOrFieldName parameter.

        The existing filters are :

        Whatever filter is applied, it first tries to get the value from a property (named propertyOrFieldName), if no such property exists it tries to read the value from a field. Reading private fields is supported by default, this can be globally disabled by calling Assertions.setAllowExtractingPrivateFields(false).

        When reading nested property/field, if an intermediate value is null the whole nested property/field is considered to be null, thus reading "address.street.name" value will return null if "street" value is null.

        As an example, let's check stuff on some special employees : 

         Employee yoda   = new Employee(1L, new Name("Yoda"), 800);
 Employee obiwan = new Employee(2L, new Name("Obiwan"), 800);
 Employee luke   = new Employee(3L, new Name("Luke", "Skywalker"), 26);

                      .containsOnly(luke);

 // 'in' filter is statically imported from Assertions.in
 // Name is bean class with 'first' and 'last' String properties

        An IntrospectionError is thrown if the given propertyOrFieldName can't be found in one of the array elements.

        Note that combining filter operators is not supported, thus the following code is not correct: 

         // Combining filter operators like not(in(800)) is NOT supported
 // -> throws UnsupportedOperationException
 assertThat(employees).filteredOn("age", not(in(800)))
                      .contains(luke);

        Example : check old employees whose age > 100: 

         Employee yoda   = new Employee(1L, new Name("Yoda"), 800);
 Employee obiwan = new Employee(2L, new Name("Obiwan"), 800);
 Employee luke   = new Employee(3L, new Name("Luke", "Skywalker"), 26);

 AtomicReferenceArray<Employee> employees = new AtomicReferenceArray<>(new Employee[]{ yoda, luke, obiwan, noname });

 assertThat(employees).filteredOn(employee -> employee.getAge() > 100)
                      .containsOnly(yoda, obiwan);
        Parameters:
        predicate - the filter predicate
        Returns:
        a new assertion object with the filtered array under test
        Throws:
        IllegalArgumentException - if the given predicate is null.
        Since:
        3.16.0

      • filteredOn

        public <U> AtomicReferenceArrayAssert<T> filteredOn​(Function<? super T,​U> function,
                                                    U expectedValue)
        Filter the array under test into a list composed of the elements for which the result of the function is equal to expectedValue.

        It allows to filter elements in more safe way than by using filteredOn(String, Object) as it doesn't utilize introspection.

        As an example, let's check all employees 800 years old (yes, special employees): 

         Employee yoda   = new Employee(1L, new Name("Yoda"), 800);
 Employee obiwan = new Employee(2L, new Name("Obiwan"), 800);
 Employee luke   = new Employee(3L, new Name("Luke", "Skywalker"), 26);
 Employee noname = new Employee(4L, null, 50);

 AtomicReferenceArray<Employee> employees = new AtomicReferenceArray<>(new Employee[]{ yoda, luke, obiwan, noname });

 assertThat(employees).filteredOn(Employee::getAge, 800)
                      .containsOnly(yoda, obiwan);

 assertThat(employees).filteredOn(e -> e.getName(), null)
                      .containsOnly(noname);
        If you need more complex filter, use filteredOn(Predicate) or filteredOn(Condition).
        Type Parameters:
        U - result type of the filter function
        Parameters:
        function - the filter function
        expectedValue - the expected value of the filter function
        Returns:
        a new assertion object with the filtered array under test
        Throws:
        IllegalArgumentException - if the given function is null.
        Since:
        3.17.0

      • allMatch

        public AtomicReferenceArrayAssert<T> allMatch​(Predicate<? super T> predicate,
                                              String predicateDescription)
        Verifies that all the elements of actual's array match the given Predicate. The predicate description is used to get an informative error message.

        Example : 

         AtomicReferenceArray<String> abc = new AtomicReferenceArray<>(new String[] {"a", "b", "c"});
 AtomicReferenceArray<String> abcc = new AtomicReferenceArray<>(new String[] {"a", "b", "cc"});

 // assertion will pass
 assertThat(abc).allMatch(s -> s.length() == 1, "length of 1");

 // assertion will fail
 assertThat(abcc).allMatch(s -> s.length() == 1, "length of 1");
        The message of the failed assertion would be: 
        Expecting all elements of:
  <["a", "b", "cc"]>
  to match 'length of 1' predicate but this element did not:
  <"cc">
        Specified by:
        allMatch in interface ObjectEnumerableAssert<AtomicReferenceArrayAssert<T>,​T>
        Parameters:
        predicate - the given Predicate.
        predicateDescription - a description of the Predicate used in the error message
        Returns:
        this object.
        Throws:
        NullPointerException - if the given predicate is null.
        AssertionError - if an element cannot be cast to T.
        AssertionError - if one or more elements don't satisfy the given predicate.
        Since:
        3.7.0

      • allSatisfy

        public AtomicReferenceArrayAssert<T> allSatisfy​(Consumer<? super T> requirements)
        Verifies that all the elements satisfy given requirements expressed as a Consumer.

        This is useful to perform a group of assertions on elements.

        Grouping assertions example: 

         // myIcelanderFriends is an AtomicReferenceArray<Person>
 assertThat(myIcelanderFriends).allSatisfy(person -> {
                                 assertThat(person.getCountry()).isEqualTo("Iceland");
                                 assertThat(person.getPhoneCountryCode()).isEqualTo("+354");
                               });
        Specified by:
        allSatisfy in interface ObjectEnumerableAssert<AtomicReferenceArrayAssert<T>,​T>
        Parameters:
        requirements - the given Consumer.
        Returns:
        this object.
        Throws:
        NullPointerException - if the given Consumer is null.
        AssertionError - if one or more elements don't satisfy given requirements.
        Since:
        3.7.0

      • anySatisfy

        public AtomicReferenceArrayAssert<T> anySatisfy​(Consumer<? super T> requirements)
        Verifies that at least one element satisfies the given requirements expressed as a Consumer.

        This is useful to check that a group of assertions is verified by (at least) one element.

        If the AtomicReferenceArray to assert is empty, the assertion will fail.

        Grouping assertions example: 

         // myIcelanderFriends is an AtomicReferenceArray<Person>
 assertThat(myIcelanderFriends).anySatisfy(person -> {
                                 assertThat(person.getCountry()).isEqualTo("Iceland");
                                 assertThat(person.getPhoneCountryCode()).isEqualTo("+354");
                                 assertThat(person.getSurname()).endsWith("son");
                               });

 // assertion fails for empty group, whatever the requirements are.
 assertThat(emptyArray).anySatisfy($ -> {
                         assertThat(true).isTrue();
                       });

        Parameters:
        requirements - the given Consumer.
        Returns:
        this object.
        Throws:
        NullPointerException - if the given Consumer is null.
        AssertionError - if all elements don't satisfy given requirements.
        Since:
        3.7.0

      • noneSatisfy

        public AtomicReferenceArrayAssert<T> noneSatisfy​(Consumer<? super T> restrictions)
        Description copied from interface: ObjectEnumerableAssert
        Verifies that no elements satisfy the given restrictions expressed as a Consumer.

        Example: 

         // assume that all icelander in myIcelanderFriends are not from Brazil
 assertThat(myIcelanderFriends).noneSatisfy(person -> {
                                  assertThat(person.getCountry()).isEqualTo("Brazil");
                                });
        Note that this assertion succeeds if the group (collection, array, ...) is empty whatever the restrictions are.
        Specified by:
        noneSatisfy in interface ObjectEnumerableAssert<AtomicReferenceArrayAssert<T>,​T>
        Parameters:
