Running tests

• Run unit and integration tests: go test -tags=integration ./...
• All unit test will be run in every build in Travis.

Enhancements (TODO)

• Use separate models for API requests and have DTO's for database model conversion. So that API requests and DB models will be independent of each other.
• Have cache/session in authentication middleware so that no need to query DB for user credentials validation.
• Add Integration tests.
• Add more unit tests.
• Horizontal scaling support with New SQL databases like Cockroach or TiDB.
• Add docker file.
• Add Makefile for build and test.
• Input fields validation for all fields like email, phone etc
• Dont take DB password in plain text from config.
• Add travis Build.
• Better error messages, like Email already exists etc.
• Add overall Architecture docs
• Run integration((e2e) tests in travis.
• Add Performance tests
