DockerSpec

Integrates seamlessly with multiple Ruby testing frameworks—RSpec, Serverspec, Infrataster, and Capybara—enabling comprehensive tests from Dockerfile validation to HTTP interactions, as shown in the usage examples.

Supports testing Docker Compose applications with resources like `docker_compose` and `its_container`, allowing integration tests for complex, multi-service setups, demonstrated in the README with wait parameters and container-specific checks.

Includes built-in retry logic via the rspec-retry gem to handle transient failures in container environments, improving reliability in CI/CD pipelines, as highlighted in the retry examples with configurable wait times.

Optimized for continuous integration with out-of-the-box examples for Travis CI and CircleCI, including configuration snippets that simplify pipeline integration, as detailed in the README's CI/CD sections.
