IsMapWithSize

public IsMapWithSize(Matcher<? super java.lang.Integer> sizeMatcher)

Method Detail

featureValueOf

protected java.lang.Integer featureValueOf(java.util.Map<? extends K,? extends V> actual)

Description copied from class: FeatureMatcher

Implement this to extract the interesting feature.

Specified by:

featureValueOf in class FeatureMatcher<java.util.Map<? extends K,? extends V>,java.lang.Integer>

Parameters:

actual - the target object

Returns:

the feature to be matched

aMapWithSize

public static <K,V> Matcher<java.util.Map<? extends K,? extends V>> aMapWithSize(Matcher<? super java.lang.Integer> sizeMatcher)

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

assertThat(myMap, is(aMapWithSize(equalTo(2))))

Parameters:

sizeMatcher - a matcher for the size of an examined Map

aMapWithSize

public static <K,V> Matcher<java.util.Map<? extends K,? extends V>> aMapWithSize(int size)

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

assertThat(myMap, is(aMapWithSize(2)))

Parameters:

size - the expected size of an examined Map

anEmptyMap

public static <K,V> Matcher<java.util.Map<? extends K,? extends V>> anEmptyMap()

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

assertThat(myMap, is(anEmptyMap()))
