It seems you wish to asset agains the size of your cont property.

system.assertEquals(1, myController.cont.size(), 'Add an assertion message here');

It would be wise to first assert the property is not null. Otherwise, your test might at some point fail with a null pointer exception, rather than an assertion message. The latter tends to be much more informative.

system.assertNotEquals(null, myController.cont, 'The property should contain query results');
system.assertEquals(1, myController.cont.size(), 'Message...');

At this point you may catch that you haven't yet called myController.search(), which appears to be what you are trying to test.
