| Check whether Message inside executorTester.getOutStreamQueue() matches tuples emitted by TestSpout. |
| We will not enable acking system and not enable timeout. |
| 2. gatherMetrics() |
| We wait for the interval for gathering metrics, and check whether the Metrics Message contains |
| the expected Metrics |
| 3. doImmediateAcks() |
| We do immediate acks, and check whether the singleton Constants.ACK_COUNT matches expected value. |
| We will not enable acking system and not enable timeout. |
| 4. lookForTimeouts() |
| We enable acking system and timeout but not ack any tuples, and check whether it will be timeout automatically |
| and calling fail(), by checking whether the singleton Constants.FAIL_COUNT matches expected value |
| 5. ackAndFail() |
| We enable acking system without timeout, and let the spout emit tuples; then we collect the corresponding tuples' |
| info, for instance: key, root and so on. Then we construct 5 acks and 5 fails and send back. |
| We will check whether the singleton Constants.ACK_COUNT and "fail count" match the expected value.</div> |
