java - Junit assert something after awaiting and handling an exception

Question

method which throws at first and second call:

public void foo() throws Exception

test:

@test
public void testFooThrowsAtFirstAndSecondTime(){
    boolean thrown;
    try {
       foo();
    } catch (Exception e) {
       thrown = true;
    }
    assertTrue(thrown);

    thrown = false;
    try {
       foo();
    } catch (Exception e) {
       thrown = true;
    }
    assertTrue(thrown);

    foo();
}

Could you help me find a better solution for this? Use of Mockito for a better solution would be also acceptable.

With better i mean, if i could avoid try/catch or even multiple try/catch in my test. In other languages or in jAssert i think even in spring there are statements like:

assertThrows(method(..)) //PseudoCode

I thought with Mockito or JUnit 4.x there is a similar thing.

I know about

@Test(expected=Exception)

But this would only be acceptable if i expect one throw and the test ends after that.

Answer 1

I don't think a one-liner per method invocation is possible.

I would write the test like this:

@Test
public void testFooThrowsAtFirstAndSecondTime() throws Exception {
  try {
    foo();
    fail("foo did not throw an exception");
  } catch (Exception ex) { }

  try{
    foo(); 
    fail("foo did not throw an exception");
  } catch (Exception ex) { }

  foo();
}
