For tests that fail on exception, the preferred method of handling them is to
let the exception propagate outward.
ie:
public void testSerialization() throws IOException {
}
Only handle the exception if the test fails if an exception is NOT thrown.
The stack trace from the exception allows much faster location of the cause of
failure than fail(), and a number of test frameworks take advantage of it.
