  • Method Details

    • contains

      public MultisetAssert<T> contains(int expectedCount, T expected)
      Verifies the actual Multiset contains the given value exactly the given number of times.

      Example : 

       Multiset<String> actual = HashMultiset.create();
 actual.add("shoes", 2);

 // assertion succeeds
 assertThat(actual).contains(2, "shoes");

 // assertions fail
 assertThat(actual).contains(1, "shoes");
 assertThat(actual).contains(3, "shoes");
      Parameters:
      expectedCount - the exact number of times the given value should appear in the set
      expected - the value which to expect
      Returns:
      this MultisetAssert for fluent chaining
      Throws:
      AssertionError - if the actual Multiset is null
      AssertionError - if the actual Multiset contains the given value a number of times different to the given count

    • containsAtLeast

      public MultisetAssert<T> containsAtLeast(int minimumCount, T expected)
      Verifies the actual Multiset contains the given value at least the given number of times.

      Example : 

       Multiset<String> actual = HashMultiset.create();
 actual.add("shoes", 2);

 // assertions succeed
 assertThat(actual).containsAtLeast(1, "shoes");
 assertThat(actual).containsAtLeast(2, "shoes");

 // assertion fails
 assertThat(actual).containsAtLeast(3, "shoes");
      Parameters:
      minimumCount - the minimum number of times the given value should appear in the set
      expected - the value which to expect
      Returns:
      this MultisetAssert for fluent chaining
      Throws:
      AssertionError - if the actual Multiset is null
      AssertionError - if the actual Multiset contains the given value fewer times than the given count

    • containsAtMost

      public MultisetAssert<T> containsAtMost(int maximumCount, T expected)
      Verifies the actual Multiset contains the given value at most the given number of times.

      Example : 

       Multiset<String> actual = HashMultiset.create();
 actual.add("shoes", 2);

 // assertions succeed
 assertThat(actual).containsAtMost(3, "shoes");
 assertThat(actual).containsAtMost(2, "shoes");

 // assertion fails
 assertThat(actual).containsAtMost(1, "shoes");
      Parameters:
      maximumCount - the maximum number of times the given value should appear in the set
      expected - the value which to expect
      Returns:
      this MultisetAssert for fluent chaining
      Throws:
      AssertionError - if the actual Multiset is null
      AssertionError - if the actual Multiset contains the given value more times than the given count
