Don't use fail() inside try-catch

[eomiso]

아래 버그가 잡혀서 추후 수정하면 좋을 듯.

Assertion methods are throwing a "java.lang.AssertionError". If this call is done within the try block of a try-catch cathing a similar error, you should make sure to test some properties of the exception. Otherwise, the assertion will never fail.

Noncompliant code example

@Test
public void should_throw_assertion_error() {
  try {
    throwAssertionError();
    Assert.fail("Expected an AssertionError!"); // Noncompliant, the AssertionError will be caught and the test will never fail.
  } catch (AssertionError e) {}
}

private void throwAssertionError() {
  throw new AssertionError("My assertion error");
}

Compliant solution

assertThrows(AssertionError.class, () -> throwAssertionError());
try {
   throwAssertionError();
   Assert.fail("Expected an AssertionError!"); // Compliant, we made sure to test that the correct error is raised
 } catch (AssertionError e) {
   Assert.assertThat(e.getMessage(), is("My assertion error"));
 }
