Beginner in Java using JUnit to test an ArrayList size

    @Test
    @DisplayName("Get all Points in Shape is working and gets the correct number output")
    public void test_Get_All_Points_On_Shape()
    {
        ArrayList<Point> points = new ArrayList<Point>(Arrays.asList(new Point[4]));
        assertEquals(points.size() == 4);
    }

the above code gives an error 

The method assertEquals(short, short) in the type Assertions is not applicable for the arguments (boolean)

How to resolve this problem?

If you use assertThat() from org.assertj.core.api.AssertionsForClassTypes.assertThat or from org.assertj.core.api.Assertions.assertThat

then you can use:

assertThat(points).hasSize(4);

You can use the Assert options appropriately as per your need. two easy methods that can be used for your case is 

assertEquals(4, points.size());
assertTrue(points.size() == 4);

depending on your requirement, you can use the assertFalse() which is also a much used method.

The method assertEquals() takes two parameters:

  • expected value and
  • actual value

What you passed is a result of equality operator on two integers, which is boolean.

You have to change this line to the following:

 assertEquals(4, points.size());

Please check http://junit.sourceforge.net/javadoc/org/junit/Assert.html#assertEquals(long,%20long)

The assertEquals method requires two parameters. Replace your code as assertEquals(4,points.size());

Either you use

assertTrue(points.size() == 4);

or

assertEquals(4, points.size());
