Advanced Feature Test Strategy

Advanced Feature Test Strategy

HeliosDB Nano advanced feature validation is organized around user-visible behavior rather than development milestones.

Test Layers

Layer	Purpose
Unit tests	Validate parsers, planners, encoders, and storage helpers
Integration tests	Validate SQL execution across storage, catalog, and protocol boundaries
Protocol tests	Validate PostgreSQL wire behavior with real client message flows
REPL tests	Validate user-facing commands and system-view discovery

Core Coverage

• SQL branching statements and branch metadata
• AS OF query variants
• Materialized view lifecycle and refresh paths
• System catalog functions
• Vector index metadata and quantization reporting
• PostgreSQL protocol authentication, TLS, and extended query execution

Focused Commands

cargo test branch_sql_integration_tests
cargo test materialized_view_tests
cargo test repl_meta_commands
cargo test --test postgres_scram_auth_tests
