NEED HELP WITH TEST FILE

import static org.junit.Assert.assertEquals;

assertEquals("North", Compass.numberToDirection(0));
}

@Test

assertEquals("Out of range: 8",
Compass.numberToDirection(8));
}

@Test
public void testSeed123() {
Compass c = new Compass(123l);
assertEquals("Southwest",
c.randomDirection());
}

// TODO - write your code below this comment.
