junit assert in thread throws exception

Question

What am I doing wrong that an exception is thrown instead of showing a failure, or should I not have assertions inside threads?

 @Test
 public void testCompl         


        

Answer 1

I ended up using this pattern it work with both Runnables and Threads. It is largely inspired from the answer of @Eyal Schneider:

private final class ThreadUnderTestWrapper extends ThreadUnderTest {
    private Exception ex;

    @Override
    public void run() {
        try {
            super.run();
        } catch ( Exception ex ) {
            this.ex = ex;
        }
    }

    public Exception getException() throws InterruptedException {
        super.join(); // use runner.join here if you use a runnable. 
        return ex;
    }
}
