- Update Login User.bru to use testuser@example.com
- Update Register User.bru to use testuser@example.com
- Update Register Admin User.bru to use maxdevices@example.com
- Standardize password to Test@Pass123! across all tests
- Add TEST_DATA.md documenting shared test credentials
- Update bruno.json with documentation reference
- Add comments linking to TEST_DATA.md for cross-reference
This alignment makes it easier to verify test failures between
Bruno API tests and Go integration tests using identical credentials.
