        import subprocess
        popen = subprocess.Popen([self.exe, 'abc', 'xyz'],
                                 stdout = open(os.devnull, 'w') if not self.TraceOn() else None)

        listener = lldb.SBListener('my.attach.listener')
        error = lldb.SBError()
        process = target.AttachToProcessWithID(listener, popen.pid, error)

        self.assertTrue(error.Success() and process, PROCESS_IS_VALID)

        import lldbutil

        listener = lldb.SBListener('my.attach.listener')
        error = lldb.SBError()
        process = target.AttachToProcessWithID(listener, popen.pid, error)

        self.assertTrue(error.Success() and process, PROCESS_IS_VALID)

checks that after the attach, there is no error condition by asserting
that error.Success() is True and we get back a valid process object.

And (from test/python_api/event/TestEvent.py),

        # Now launch the process, and do not stop at entry point.
        error = lldb.SBError()
        process = target.Launch(listener, None, None, None, None, None, None, 0, False, error)
        self.assertTrue(error.Success() and process, PROCESS_IS_VALID)

checks that after calling the target.Launch() method there's no error
condition and we get back a void process object.") SBError;
