| * of a test execution barrier (see its documentation for details). To simplify |
| * the test execution flow, it is encouraged that any communication between |
| * threads (e.g. a nanoapp and the main test thread) through this |
| * TestEventQueue. In this way, we can design simulation tests in a way that |
| * validates an expected sequence of events in a well-defined manner. |
| * |
| * To avoid the test from potentially stalling, we also push a timeout event |
| * to the TestEventQueue once a fixed timeout has elapsed since the start of |
| * this test. |
