Updated Summary

Implemented the user registration API endpoint for the TreeO2 backend, with full test coverage, Swagger documentation, and test environment setup.

Changes

Registration API:

auth.types.ts: added RegisterRequestBody and RegisterResponse interfaces
auth.schemas.ts : added registerSchema with Zod validation
auth.repository.ts : added findUserByEmail(), findRoleByName(), createUser() methods
auth.service.ts : added register() with full business logic
auth.controller.ts : added register() method
auth.routes.ts : added POST /auth/register route
auth.docs.ts : added Swagger documentation for register endpoint

Test Coverage:

tests/unit/auth.test.ts : 4 unit tests for AuthService.register()
tests/integration/auth.test.ts : 6 integration tests for POST /auth/register

Test Environment Setup:

tests/setup.ts : configures environment variables for test runner
jest.config.js : updated to wire setup file and test tsconfig
tsconfig.test.json : TypeScript config for test files
.env.test.example : template for teammates to set up test environment

Validation Rules

email - valid format, max 300 characters, unique
password - min 8, max 72 (bcrypt limit), must contain uppercase, number and special character
role - must be one of FARMER, INSPECTOR, MANAGER, ADMIN, DEVELOPER

Test Coverage

Valid registration → 201 success
Duplicate email → 409 DATA_002
Weak password → 400 VAL_001 with detailed errors
Invalid role → 400 VAL_001 with enum error
Password hash never exposed in response
Tested locally and through Docker and Swagger

requestId included in all error responses for traceability

@snehagopalappa this needs unit and integration tests.

@snehagopalappa, Please update your branch with master branch

[snehagopalappa]

@snehagopalappa this needs unit and integration tests.

Unit and integration tests have been added. 4 unit tests covering the service layer and 6 integration tests covering all validation scenarios. Test environment setup files also included for the team.

@snehagopalappa Could you please upate your branch with latest master version. Most of your test configurations should be redundant now, Please have a look.

Closing this pr. The validation, password hashing and duplicate check logic from this register endpoint has been integrated into POST /users in the user management module instead(pr #54).
