This would be a .serverError - that is, equal to a 500 I'm REST.

2. Regarding BaseMindClientTests, The server certificate, key, cacert were added in test class file, this can be moved to some other file.

Sure

3.Default constants like DEFAULT_API_GATEWAY_ADDRESS, etc can be moved to some constants file.

If it was a bigger application, sure. In this case I think it's fine.

4.Missing function definitions can be added.

Can you explain?
