    • isDeepEqualTo

      public Int2DArrayAssert isDeepEqualTo(int[][] expected)
      Verifies that the actual 2D array is deeply equal to the given one.

      Two arrays are considered deeply equal if both are null or if they refer to arrays that contain the same number of elements and all corresponding pairs of elements in the two arrays are deeply equal.

      Example: 

       // assertion will pass
 assertThat(new int[][] {{1, 2}, {3, 4}}).isDeepEqualTo(new int[][] {{1, 2}, {3, 4}});

 // assertions will fail
 assertThat(new int[][] {{1, 2}, {3, 4}}).isDeepEqualTo(new int[][] {{1, 2}, {9, 10}});
 assertThat(new int[][] {{1, 2}, {3, 4}}).isDeepEqualTo(new int[][] {{1, 2, 3}, {4}});
      Specified by:
      isDeepEqualTo in class Abstract2DArrayAssert<Int2DArrayAssert,int[][],Integer>
      Parameters:
      expected - the given value to compare the actual value to.
      Returns:
      this assertion object.

    • isEqualTo

      public Int2DArrayAssert isEqualTo(Object expected)
      Verifies that the actual int[][] is equal to the given one.

      WARNING! This method will use equals to compare (it will compare arrays references only).
      Unless you specify a comparator with AbstractAssert.usingComparator(Comparator), it is advised to use isDeepEqualTo(int[][]) instead.

      Example: 

       int[][] array = {{1, 2}, {3, 4}};

 // assertion will pass
 assertThat(array).isEqualTo(array);

 // assertion will fail as isEqualTo calls equals which compares arrays references only.
 assertThat(array).isEqualTo(new int[][] {{1, 2}, {3, 4}});
      Specified by:
      isEqualTo in interface Assert<Int2DArrayAssert,int[][]>
      Overrides:
      isEqualTo in class AbstractAssert<Int2DArrayAssert,int[][]>
      Parameters:
      expected - the given value to compare the actual int[][] to.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual int[][] is not equal to the given one.

    • isNullOrEmpty

      public void isNullOrEmpty()
      Verifies that the actual array is null or empty, empty means the array has no elements, said otherwise it can have any number of rows but all rows must be empty.

      Example: 

       // assertions will pass
 int[][] array = null;
 assertThat(array).isNullOrEmpty();
 assertThat(new int[][] { }).isNullOrEmpty();
 assertThat(new int[][] {{ }}).isNullOrEmpty();
 // this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
 assertThat(new int[][] {{ }, { }, { }}).isNullOrEmpty();

 // assertion will fail
 assertThat(new int[][] {{ 1 }, { 2 }}).isNullOrEmpty();

    • isEmpty

      public void isEmpty()
      Verifies that the actual array is empty, empty means the array has no elements, said otherwise it can have any number of rows but all rows must be empty.

      Example: 

       // assertions will pass
 assertThat(new int[][] {{}}).isEmpty();
 // this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
 assertThat(new int[][] {{ }, { }, { }}).isEmpty();

 // assertions will fail
 assertThat(new int[][] {{ 1 }, { 2 }}).isEmpty();
 int[][] array = null;
 assertThat(array).isEmpty();

    • isNotEmpty

      public Int2DArrayAssert isNotEmpty()
      Verifies that the actual array is not empty, not empty means the array has at least one element.

      Example: 

       // assertions will pass
 assertThat(new int[][] {{ 1 }, { 2 }}).isNotEmpty();
 assertThat(new int[][] {{ }, { 2 }}).isNotEmpty();

 // assertions will fail
 assertThat(new int[][] { }).isNotEmpty();
 assertThat(new int[][] {{ }}).isNotEmpty();
 // this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
 assertThat(new int[][] {{ }, { }, { }}).isNotEmpty();
 int[][] array = null;
 assertThat(array).isNotEmpty();
      Returns:
      this assertion object.

    • hasDimensions

      public Int2DArrayAssert hasDimensions(int expectedFirstDimension, int expectedSecondDimension)
      Verifies that the actual 2D array has the given dimensions.

      Example: 

       // assertion will pass
 assertThat(new int[][] {{1, 2, 3}, {4, 5, 6}}).hasDimensions(2, 3);

 // assertions will fail
 assertThat(new int[][] { }).hasSize(1, 1);
 assertThat(new int[][] {{1, 2, 3}, {4, 5, 6}}).hasDimensions(3, 2);
 assertThat(new int[][] {{1, 2, 3}, {4, 5, 6, 7}}).hasDimensions(2, 3);
      Parameters:
      expectedFirstDimension - the expected number of values in first dimension of the actual array.
      expectedSecondDimension - the expected number of values in second dimension of the actual array.
      Returns:
      this assertion object.

    • hasNumberOfRows

      public Int2DArrayAssert hasNumberOfRows(int expected)
      Verifies that the actual two-dimensional array has the given number of rows.

      Example: 

       // assertion will pass
 assertThat(new int[][] {{1, 2, 3}, {4, 5, 6}}).hasNumberOfRows(2);
 assertThat(new int[][] {{1}, {1, 2}, {1, 2, 3}}).hasNumberOfRows(3);

 // assertions will fail
 assertThat(new int[][] { }).hasNumberOfRows(1);
 assertThat(new int[][] {{1, 2, 3}, {4, 5, 6}}).hasNumberOfRows(3);
 assertThat(new int[][] {{1, 2, 3}, {4, 5, 6, 7}}).hasNumberOfRows(1);
      Parameters:
      expected - the expected number of rows of the two-dimensional array.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual number of rows are not equal to the given one.

    • hasSameDimensionsAs

      public Int2DArrayAssert hasSameDimensionsAs(Object array)
      Verifies that the actual int[][] has the same dimensions as the given array.

      Parameter is declared as Object to accept both Object and primitive arrays.

      Example: 
       int[][] intArray = {{1, 2, 3}, {4, 5, 6}};
 char[][] charArray = {{'a', 'b', 'c'}, {'d', 'e', 'f'}};

 // assertion will pass
 assertThat(intArray).hasSameDimensionsAs(charArray);

 // assertions will fail
 assertThat(intArray).hasSameDimensionsAs(new int[][] {{'a', 'b'}, {'c', 'd'}, {'e', 'f'}});
 assertThat(intArray).hasSameDimensionsAs(new int[][] {{'a', 'b'}, {'c', 'd', 'e'}});
 assertThat(intArray).hasSameDimensionsAs(new int[][] {{'a', 'b', 'c'}, {'d', 'e'}});
      Parameters:
      array - the array to compare dimensions with actual int[][].

      Verifies that the actual array does not contain the given value at the given index.
