📝 Walkthrough

Walkthrough

The pull request introduces comprehensive testing infrastructure and development tooling. Changes include adding test dependencies (tokio, mockall, testcontainers, wiremock, postgres), removing async-http-client, enabling Docker Compose volumes and networking for Postgres, adding a development entrypoint script with Docker/network initialization checks, exposing utility helper functions, and creating test modules covering compression, deserialization, edge key decoding, cron normalization, and database connectivity.

Changes

Cohort / File(s)	Summary
Dependency Management Cargo.toml	Added dev-dependencies for testing (tokio, mockall, testcontainers, wiremock) and production dependencies for Postgres integration (testcontainers-modules, postgres); removed async-http-client.
Docker Infrastructure Makefile, docker-compose.yml, docker/entrypoints/app-dev-entrypoint.sh	Added Makefile target up pointing to new entrypoint script; uncommented cargo-target volume mapping and cargo-registry volume in compose; added localhost host-gateway mapping and updated EDGE_KEY token; created new bash entrypoint with Docker daemon startup checks (platform-specific), network creation, and docker-compose orchestration.
Test Module Wiring src/main.rs, src/tests/mod.rs, src/tests/domain/mod.rs, src/tests/utils/mod.rs	Added test-only module declarations to enable test scaffolding and organize test suites under utils and domain namespaces.
Database Connectivity Tests src/tests/domain/postgres.rs	Created async test using testcontainers to spin up Postgres container, configure DatabaseFactory, and verify database ping connectivity.
Utility Function Tests src/tests/utils/normalize_cron_tests.rs, src/tests/utils/common_tests.rs, src/tests/utils/compress_tests.rs, src/tests/utils/deserializer.rs, src/tests/utils/edge_key_tests.rs	Added five test modules covering cron normalization validation, backup method/JSON conversion, async compression/decompression workflows, snake_case deserialization, and edge key Base64 decoding with error cases.
Utility Function Exposure src/utils/deserializer.rs, src/utils/compress.rs	Exposed to_snake_case and camel_to_snake as public functions; removed commented-out code line.
