You should also modify one of the existing arguments
e.g:
opts.arguments[1] = "NewOptionsTest";
Expect.equals("NewOptionsTest", opts.arguments[1]);

+
+  // Check that a new options object still gets the original arguments.
+  var opts2 = new Options();
+  Expect.equals(3, opts2.arguments.length);
+  Expect.equals(10, Math.parseInt(opts2.arguments[0]));
+  Expect.equals("OptionsTest", opts2.arguments[1]);
+  Expect.equals(20, Math.parseInt(opts2.arguments[2]));
+}
