dotnet-testing-advanced-testcontainers-database

The skill presents a coherent and proportionate footprint for its stated purpose: it demonstrates advanced, containerized database integration testing with Testcontainers, using both PostgreSQL and SQL Server, and supports EF Core and Dapper usage, container sharing via collection fixtures, and externalized SQL scripts. The main security concern is embedded sample credentials in code, which should be avoided or redacted in real repositories and replaced with secure test secrets management. Otherwise, data flows and installation sources are appropriate and aligned with the goal.
