Roadmap: Achieve 80% Test Coverage

[joshrotenberg]

Overview

Improve test coverage across all crates to ensure reliability and maintainability.

Current Status (Updated: 2025-09-04)

• redis-cloud: 12/21 handlers tested (~57%)
• redis-enterprise: 22/29 handlers tested (~76%) with 261 test functions
• redisctl: CLI integration tests in progress

Progress Since Opening

• ✅ Enterprise API: Achieved 76% handler coverage
• ✅ All critical security operations tested (auth, ACLs, users)
• ✅ Comprehensive wiremock-based testing framework established
• ✅ CI runs all tests on every PR

Remaining Work

Redis Cloud (Priority - See #12)

Missing test coverage for 9 handlers:

• api_keys_tests.rs - API key management
• billing_tests.rs - Billing and invoices
• sso_tests.rs - SSO/SAML configuration
• crdb_tests.rs - Active-Active databases
• fixed_tests.rs - Essentials subscriptions
• private_service_connect_tests.rs - PSC services
• transit_gateway_tests.rs - TGW attachments
• Complete database_tests.rs (currently minimal)
• Complete subscription_tests.rs (currently minimal)

Redis Enterprise (Enhancement)

• Add tests for remaining 7 handlers
• Increase test density for complex operations
• Add failure scenario tests

CLI Testing

• Integration tests for command workflows
• Profile management tests
• Output format tests (JSON, YAML, Table)
• Error handling and validation tests

Test Requirements

• Mock API responses using wiremock
• Test success and error scenarios
• Validate request headers and bodies
• Test retry logic and timeouts
• Test concurrent operations

Success Criteria

• 80% overall code coverage
• 90% coverage for Cloud API handlers
• 100% coverage for critical security paths
• All public APIs have test coverage
• Performance regression tests

Next Steps

1. Complete Cloud API test files (Complete Redis Cloud API test coverage (9/21 handlers missing tests) #12)
2. Add CLI integration test suite
3. Set up code coverage reporting
4. Add mutation testing for quality

Progress Update

Completed since issue creation:

✅ fixed_databases_tests.rs - Created
✅ fixed_subscriptions_tests.rs - Created
✅ Test coverage has increased significantly (238 test files in the project)

Still missing:

• ❌ api_keys_tests.rs - API key management
• ❌ billing_tests.rs - Billing and invoices
• ❌ sso_tests.rs - SSO/SAML configuration
• ❌ crdb_tests.rs - Active-Active databases
• ❌ private_service_connect_tests.rs - PSC services
• ❌ transit_gateway_tests.rs - TGW attachments

The issue mentioned we're at 90%+ coverage for redis-cloud. The remaining test files would get us to 100%.

[joshrotenberg]

Closing as too high-level to be actionable. Test coverage is now an implicit part of our development workflow - all new features require tests, and gaps are filled as discovered. Current state: 225+ CLI tests, comprehensive wiremock integration tests, and handler coverage at 95%+ for redis-cloud and 100% for redis-enterprise.
