Structure Go testing across the pyramid by using stretchr/testify for unit tests, uber-go/mock for integration tests, and testcontainers-go for end-to-end tests, ensuring isolated components and real-world dependency coverage.

The best way to mock external dependencies in Go integration tests is using uber-go/mock to isolate components and validate interactions, ensuring components work together as expected without relying on real external services.

Yes, you need testcontainers-go configured to execute end-to-end tests with real-world dependencies in containers, ensuring the entire Go system functions correctly across integrated components and external services.

Stretchr/testify works with Go unit tests by providing assertion libraries that simplify validating individual components, allowing developers to isolate logic and write comprehensible test cases without boilerplate code.

Yes, you can use this approach for acceptance testing in Go applications to validate business logic and user-facing functionality, ensuring the entire system meets requirements from unit tests to end-to-end validation.
