    • isDeepEqualTo

      public Object2DArrayAssert<ELEMENT> isDeepEqualTo(ELEMENT[][] expected)
      Verifies that the actual ELEMENT[][] is deeply equal to the given one.

      Two array references 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 String[][] {{"1", "2"}, {"3", "4"}}).isDeepEqualTo(new String[][] {{"1", "2"}, {"3", "4"}});

 // assertions will fail
 assertThat(new String[][] {{"1", "2"}, {"3", "4"}}).isDeepEqualTo(new String[][] {{"1", "2"}, {"9", "0"}});
 assertThat(new String[][] {{"1", "2"}, {"3", "4"}}).isDeepEqualTo(new String[][] {{"1", "2", "3"}, {"4"}});
      Specified by:
      isDeepEqualTo in class Abstract2DArrayAssert<Object2DArrayAssert<ELEMENT>,ELEMENT[][],ELEMENT>
      Parameters:
      expected - the given value to compare the actual value to.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual value is not deeply equal to the given one.

    • isEqualTo

      public Object2DArrayAssert<ELEMENT> isEqualTo(Object expected)
      Verifies that the actual ELEMENT[][] 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(Object[][]) instead.

      Example: 

       String[][] 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 String[][] {{"1", "2"}, {"3", "4"}});
      Specified by:
      isEqualTo in interface Assert<Object2DArrayAssert<ELEMENT>,ELEMENT[][]>
      Overrides:
      isEqualTo in class AbstractAssert<Object2DArrayAssert<ELEMENT>,ELEMENT[][]>
      Parameters:
      expected - the given value to compare the actual ELEMENT[][] to.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual ELEMENT[][] is not equal to the given one.

    • isNullOrEmpty

      public void isNullOrEmpty()
      Verifies that the actual ELEMENT[][] 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
 String[][] array = null;
 assertThat(array).isNullOrEmpty();
 assertThat(new String[][] { }).isNullOrEmpty();
 assertThat(new String[][] { { } }).isNullOrEmpty();
 // this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
 assertThat(new String[][] { { }, { }, { } }).isNullOrEmpty();

 // assertion will fail
 assertThat(new String[][] { {'a'}, {'b'} }).isNullOrEmpty();
      Throws:
      AssertionError - if the actual ELEMENT[][] is not null or not empty.

    • isEmpty

      public void isEmpty()
      Verifies that the actual ELEMENT[][] 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 String[][] { {} }).isEmpty();
 // this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
 assertThat(new String[][] { { }, { }, { } }).isEmpty();

 // assertions will fail
 assertThat(new String[][] { {'a'}, {'b'} }).isEmpty();
 String[][] array = null;
 assertThat(array).isEmpty();
      Throws:
      AssertionError - if the actual ELEMENT[][] is not empty.

    • isNotEmpty

      public Object2DArrayAssert<ELEMENT> isNotEmpty()
      Verifies that the actual ELEMENT[][] is not empty, not empty means the array has at least one char element.

      Example: 

       // assertion will pass
 assertThat(new String[][] { {'a'}, {'b'} }).isNotEmpty();
 assertThat(new String[][] { { }, {'b'} }).isNotEmpty();

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

    • hasDimensions

      Verifies that the actual ELEMENT[][] has the the given dimensions.

      Example: 

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

      Parameters:
      expectedFirstDimension - the expected number of values in first dimension of the actual ELEMENT[][].
      expectedSecondDimension - the expected number of values in second dimension of the actual ELEMENT[][].
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the number of values of the actual ELEMENT[][] is not equal to the given one.

    • hasNumberOfRows
