### Execute unit tests

The unit test is currently only for the server API interface part. Execute the following command to perform the unit test:

```
cd wolf/server
npm run test
```

After execution, if all tests are successful, the output will look like this:

```
➜  server git:(master) ✗ npm run test

> wolf-server@0.1.0 test
> ./node_modules/.bin/nyc --reporter=html mocha test/*.test.js --exit --timeout 10000

After all the unit tests are executed, a coverage report will be generated in `server/coverage`. The current code statement coverage is around `92%`.
