title: how to perform a functional test on a triangle
body: <p>I am trying to do functional testing to check a triangle. i have three int input. The three input variables each describe the lengths of each side of a triangle. The lengths of the sides of the triangle should be less than or equal to 1000. The output of this method will be one of 5 possible values: 1 for a scalene triangle, 2 for a isosceles triangle, 3 for an equilateral triangle, 4 for values that do not describe a triangle, and 5 for values that are out of bounds.</p>
  
  <p>this is the first test that I wrote, but I have no idea if its correct or not. </p>
  
  <pre><code>public class TriangleTypeFunctionalTest {
      @Before
      public void setUp() throws Exception {
      }
  
      @Test
      public void testTriangleScalene(x,y,z) {
          if(x &lt; 1000 and y &lt;1000 and z&lt; 1000){
              if ( ( x != y ) and ( x != z ) and ( y !=z ) )  
                  return True;
              else
                  return False;
          }
          else
              return False;
  
      }
  
  }
  </code></pre>
  
  <p>I need some help understanding and how to do this</p>
