Add before and after logging for unit tests

Currently we have these logs for integration tests only.

This adds the following log at the start:
```
logger.info("[{}]: before test", getTestName());
```

and this is logged at the end, but before any clean up done in sub classes

```
 logger.info("[{}]: after test", getTestName());
```
