assertThat(myMap, is(aMapWithSize(equalTo(2))))
Parameters
sizeMatcher:Matcher<? super Integer>

a matcher for the size of an examined java.util.Map

aMapWithSizeback to summary
public static <K, V> Matcher<Map<? extends K, ? extends V>> aMapWithSize(int size)

Creates a matcher for java.util.Maps that matches when the size() method returns a value equal to the specified size. For example: 

assertThat(myMap, is(aMapWithSize(2)))
Parameters
size:int

the expected size of an examined java.util.Map

anEmptyMapback to summary
public static <K, V> Matcher<Map<? extends K, ? extends V>> anEmptyMap()

Creates a matcher for java.util.Maps that matches when the size() method returns zero. For example: 

assertThat(myMap, is(anEmptyMap()))
featureValueOfback to summary
