IterableAssert<ELEMENT> |
contains(ELEMENT... values)
Verifies that the actual group contains the given values, in any order.

Verifies that the actual
Iterable contains at least one of the given values. |
IterableAssert<ELEMENT> |
containsExactly(ELEMENT... values)
Verifies that the actual group contains exactly the given values and nothing else, in order.
This assertion should only be used with groups that have a consistent iteration order (i.e. |

containsExactlyInAnyOrder(ELEMENT... values)
Verifies that the actual group contains exactly the given values and nothing else, in any order.
|
IterableAssert<ELEMENT> |

|
IterableAssert<ELEMENT> |
containsOnlyOnce(ELEMENT... values)
Verifies that the actual group contains the given values only once.
|
IterableAssert<ELEMENT> |

Verifies that the actual group does not contain the given values.
|
IterableAssert<ELEMENT> |

AbstractIterableAssert
Function
s to extract the values from the Iterable
's elements into a new Iterable
composed of Tuple
s (a simple data structure containing the extracted values), this new Iterable
becoming the
object under test.
It allows you to test values from the Iterable
's elements instead of testing the elements themselves, which sometimes can be
much less work!
The Tuple data corresponds to the extracted values from the Iterable's elements, for instance if you pass functions extracting "id", "name" and "email" values then each Tuple data will be composed of an id, a name and an email extracted from the element of the initial Iterable (the Tuple's data order is the same as the given functions order).
Let's take a look at an example to make things clearer :
// 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.
List<TolkienCharacter> fellowshipOfTheRing = new ArrayList<TolkienCharacter>();
fellowshipOfTheRing.add(new TolkienCharacter("Frodo", 33, HOBBIT));
fellowshipOfTheRing.add(new TolkienCharacter("Sam", 38, HOBBIT));
fellowshipOfTheRing.add(new TolkienCharacter("Gandalf", 2020, MAIA));
fellowshipOfTheRing.add(new TolkienCharacter("Legolas", 1000, ELF));
fellowshipOfTheRing.add(new TolkienCharacter("Pippin", 28, HOBBIT));
fellowshipOfTheRing.add(new TolkienCharacter("Gimli", 139, DWARF));
fellowshipOfTheRing.add(new TolkienCharacter("Aragorn", 87, MAN);
fellowshipOfTheRing.add(new TolkienCharacter("Boromir", 37, MAN));
// let's verify 'name', 'age' and Race of some TolkienCharacter in fellowshipOfTheRing :
assertThat(fellowshipOfTheRing).extracting(TolkienCharacter::getName,
character > character.getAge(),
TolkienCharacter::getRace)
.containsOnly(tuple("Frodo", 33, HOBBIT),
tuple("Sam", 38, HOBBIT),
tuple("Gandalf", 2020, MAIA),
tuple("Legolas", 1000, ELF),
tuple("Pippin", 28, HOBBIT),
tuple("Gimli", 139, DWARF),
tuple("Aragorn", 87, MAN),
tuple("Boromir", 37, MAN));
You can use lambda expression or a method reference to extract the expected values.
Use Tuple.tuple(Object...)
to initialize the expected values.
Note that the order of the extracted tuples list 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 tuples order.
