4. The coverage data is stored on each covered service side, so if one service needs to restart during test, this service's coverage data will be lost. For this case, you can use following steps to handle:
1. Before the service restarts, collect coverage with `goc profile -o a.cov`
2. After service restarted and test finished, collect coverage again with `goc profile -o b.cov`
3. Merge two coverage profiles together: `goc merge a.cov b.cov -o merge.cov`
