Can anyone help as to why my test cases is failing. My class implementation looks correct.

public Edge removeEdge (V dest) { Message msg; Edge removedEdge = null; for (Edge EL : edgeList) { if (this.edgeList.size() == 1) { == dest) { if (this.getv() eL.getSource() && eL.getDest() edgeList.remove (dest); } == != dest) { else if (this.getv() eL.getSource () && eL.getDest() msg = Message.Warning5; return null; } else if (this.getv() != eL.getSource () && eL.getDest() != dest) { msg = Message.Warning6; return null; } else { } } else { } } return removedEdge; } @Test public void test_removeE() { Edge el = new Edge("1", "4"); graph.addE(21); Edge e2 = graph.removeE(Inew Edge("1", "4")); Assert.assertEquals(true, el.equals(22)); } Failure Trace java.lang.AssertionError. expected: true but was: E at graph.DGraphTest.test_removeE(DGraphTest.java:112) public Edge removeEdge (V dest) { Message msg; Edge removedEdge = null; for (Edge EL : edgeList) { if (this.edgeList.size() == 1) { == dest) { if (this.getv() eL.getSource() && eL.getDest() edgeList.remove (dest); } == != dest) { else if (this.getv() eL.getSource () && eL.getDest() msg = Message.Warning5; return null; } else if (this.getv() != eL.getSource () && eL.getDest() != dest) { msg = Message.Warning6; return null; } else { } } else { } } return removedEdge; } @Test public void test_removeE() { Edge el = new Edge("1", "4"); graph.addE(21); Edge e2 = graph.removeE(Inew Edge("1", "4")); Assert.assertEquals(true, el.equals(22)); } Failure Trace java.lang.AssertionError. expected: true but was: E at graph.DGraphTest.test_removeE(DGraphTest.java:112)
