How do I catch the two exceptions correctly in junit, because right now they are being caught and my tests are failing. – letter Q May 14 '13 at 20:48

Show us more of your test, and the stack trace of the exception. The snippet you gave doesn't even invoke the constructor. Tell us what you're trying to test. – JB Nizet May 14 '13 at 20:51

You can declare on the @Test annotation that, for the test to pass, it must throw these exceptions:
@Test(expected = NullPointerException.class)
public void testSynapseOne() {
// test
}
@Test(expected = IllegalStateException.class)
public void testSynapseTwo() {
// test
}
Of course, you have to be sure you're testing the right thing - currently, your tests don't make use of the constructor, which is the critical piece you want to test.
Oh - you don't want to have your tests extend TestCase unless you need compatibility with JUnit3.x.

You can use the annotation @Test(expected = TheClassException.class) to write a test which is supposed to throws the exception of class TheClassException
