AbstractAssertYou must set it before calling the assertion otherwise it is ignored as the failing assertion breaks the chained call by throwing an AssertionError.
The new error message is built using String.format(String, Object...) if you provide args parameter (if you
don't, the error message is taken as it is).

Assert object that allows performing assertions on the size of the Map under test.
Once this method is called, the object under test is no longer the Map but its size,
to perform assertions on the Map, call AbstractMapSizeAssert.returnToMap().
Example :
Map<Ring, TolkienCharacter> ringBearers = newHashMap(entry(oneRing, frodo),
entry(nenya, galadriel),
entry(narya, gandalf));
// assertion will pass:
assertThat(ringBearers).size().isGreaterThan(1)
.isLessThanOrEqualTo(3)
returnToMap().contains(entry(oneRing, frodo),
entry(nenya, galadriel),
entry(narya, gandalf));
// assertion will fail:
assertThat(ringBearers).size().isGreaterThan(5);AbstractMapSizeAssert to allow assertions on the number of key-value mappings in this mapNullPointerException - if the given map is null.public AbstractListAssert<?,List<? extends Object>,Object,ObjectAssert<Object>> extracting(Object... keys)
For example, if you specify "id", "name" and "email" keys then the array will contain the map values for these keys, you can then perform array assertions on the extracted values.
If a given key is not present in the map under test, a null value is extracted.
Example:
Map<String, Object> map = new HashMap<>();
map.put("name", "kawhi");
map.put("age", 25);
assertThat(map).extracting("name", "age")
.contains("kawhi", 25);Note that the order of extracted keys value is consistent with the iteration order of the array under test.
Nested keys are not yet supported, passing "name.first" won't get a value for "name" and then try to extract "first" from the previously extracted value, instead it will simply look for a value under "name.first" key.
keys - the keys used to get values from the map under testpublic AbstractListAssert<?,List<?>,Object,ObjectAssert<Object>> extractingFromEntries(Function<? super Map.Entry<K,V>,Object> extractor)
Function to extract a value from the Map's entries.
The extracted values are stored in a new list becoming the object under test.
Let's take a look at an example to make things clearer :
// Build a Map that associates family roles and name of the Simpson familly
Map<String, CartoonCharacter> characters = new HashMap<>();
characters.put("dad", new CartoonCharacter("Omer"));
characters.put("mom", new CartoonCharacter("Marge"));
characters.put("girl", new CartoonCharacter("Lisa"));
characters.put("boy", new CartoonCharacter("Bart"));
assertThat(characters).extractingFromEntries(e -> e.getValue().getName())
.containsOnly("Omer", "Marge", "Lisa", "Bart");extractor - the extractor function to extract a value from an entry of the Map under test.public AbstractListAssert<?,List<? extends Tuple>,Tuple,ObjectAssert<Tuple>> extractingFromEntries(Function<? super Map.Entry<K,V>,Object>... extractors)
Functions to extract values from the Map's entries.
The extracted values are stored in a new list composed of Tuples (a simple data structure containing the extracted values),
this new list becoming the object under test.
This method works as extractingFromEntries(java.util.function.Function) except
that it is designed to extract multiple values from the Map entries.
That's why here the new object under test is a List of Tuples.
The Tuple data corresponds to the extracted values from the Map's entries, for instance if you pass functions extracting the "id", "name" and "email" values then each Tuple data will be composed of an id, a name and an email extracted from the entry of the Map (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 Map that associates family roles and name of the Simpson familly
Map<String, CartoonCharacter> characters = new HashMap<>();
characters.put("dad", new CartoonCharacter("Omer"));
characters.put("mom", new CartoonCharacter("Marge"));
characters.put("girl", new CartoonCharacter("Lisa"));
characters.put("boy", new CartoonCharacter("Bart"));
assertThat(characters).extractingFromEntries(e -> e.getKey(), e -> e.getValue().getName())
.containsOnly(tuple("dad", "Omer"),
tuple("mom", "Marge"),
tuple("girl", "Lisa"),
tuple("boy", "Bart"));HashSet, you won't be able to make any assumptions on the extracted values
order.extractors - the extractor functions to extract values from an entry of the Map under test.public AbstractListAssert<?,List<? extends Object>,Object,ObjectAssert<Object>> flatExtracting(String... keys)
If a given key is not present in the map under test, a null value is extracted.
If a given key value is not an Iterable or an array, it is simply extracted but (obviously) not flattened.
Example:
List<String> names = asList("Dave", "Jeff");
LinkedHashSet<String> jobs = newLinkedHashSet("Plumber", "Builder");
Iterable<String> cities = asList("Dover", "Boston", "Paris");
int[] ranks = { 1, 2, 3 };
Map<String, Object> map = new LinkedHashMap<>();
map.put("name", names);
map.put("job", jobs);
map.put("city", cities);
map.put("rank", ranks);
assertThat(map).flatExtracting("name","job","city", "rank")
.containsExactly("Dave", "Jeff",
"Plumber", "Builder",
"Dover", "Boston", "Paris",
1, 2, 3);
// the order of values in the resulting array is the order of map keys then key values:
assertThat(map).flatExtracting("city", "job", "name")
.containsExactly("Dover", "Boston", "Paris",
"Plumber", "Builder",
"Dave", "Jeff");
// contains exactly null twice (one for each unknown keys)
assertThat(map).flatExtracting("foo", "name", "bar")
.containsExactly(null, "Dave", "Jeff", null);
// if the key value is not an iterable/array, it will be simply extracted but not flattened.
map.put("year", 2017));
assertThat(map).flatExtracting("name","job","year")
.containsExactly("Dave", "Jeff", "Plumber", "Builder", "Dover", 2017);Note that the order of values in the resulting array is the order of the map keys iteration then key values.
