+ } Review Comment: I don't understand this code. Assuming in future we test both Yammer and Dropwizard... how do you expect we should write the tests? It looks it is reading some config from `testConfig.json` but it is not possible to read two different files so... why is this better than forcing to use Yammer in the code? -- This is an automated message from the Apache Git Service.
