1 Here is a test class and you are going to write the class it tests. At the end of the tests, you ll find the javadocs for the class you are creating. You can use them to more fully understand the methods you are required to build import static org.junit.assert.*; import org.junit.before; import org.junit.test; * Tests for a class that converts scores to letter grades Merlin * public class PaperTest Grader g; * Just create the public void setup() g = new Grader(); * 70 is the score required to pass when we use pass/fail * grading public void testpassfail() assertfalse(g.pass(69)); asserttrue(g.pass(70)); * Early warning grades are: D, F, and PA (for Pass) public void testearlywarninggrade() assertequals("pa", g.earlywarninggrade(70)); assertequals("d", g.earlywarninggrade(69)); assertequals("d", g.earlywarninggrade(60)); assertequals("f", g.earlywarninggrade(59));
