What it does

Testcontainers-go simplifies automated testing by programmatically creating and cleaning up container-based dependencies for integration and smoke tests in Go applications.

When to use it

•When you need to test database integrations without affecting the main database
•When you want to ensure your application works with different versions of a dependency
•When you need to test your application in a isolated, ephemeral environment

Ready-to-paste prompt

Run `go test -v ./examples/mysql` to see an example of testing a MySQL database integration

Heads up: Make sure you have Docker installed and running on your machine, as testcontainers-go relies on Docker to create and manage containers
