Testcontainers is a dotnet standard 2.0 library that supports NUnit and XUnit tests, providing lightweight, throwaway instances of common databases or anything else that can run in a Docker container.
Uses common Microsoft dependency injection patterns, app and host settings, and Microsoft Extensions Logging (MEL).
This is a port of testcontainers-java for dotnet.
