events.add(new LogNotificationEvent(timestamp, "ERROR", "org.codelibs.fess.TestClass", "Something went wrong",
                "java.lang.NullPointerException: null\n\tat org.codelibs.fess.TestClass.doSomething(TestClass.java:42)"));

        String details = testableJob.testFormatDetails(events);

        assertNotNull(details);
        assertTrue(details.contains("Total: 1 event(s)"));

If you depended on exceptions not being received by dependencies with `yield`, and receiving an exception breaks the code after `yield`, you can use a block with `try` and `finally`:

```Python
async def do_something():
    try:
        yield something
    finally:
        some_cleanup()
```

...that way the `finally` block is run regardless of any exception that might happen.
