This dev container is configured to match the GitHub Actions test matrix with the following configuration:

• Ruby version: 3.4
• Redis version: latest
• Rack version: 3

1. Open this repository in your editor (Cursor, VS Code, etc.)
2. When prompted, click "Reopen in Container" (or run the command "Dev Containers: Reopen in Container")
3. Wait for the container to build and start
4. Once inside the container, dependencies will be automatically installed via bundle install

To run the full test suite:

bundle exec rake

To run a specific test file:

bundle exec ruby test/resque_test.rb

To run tests with verbose output:

VERBOSE=1 bundle exec rake

If you want to test with different versions, you can modify the environment variables and reinstall dependencies:

# Example: Test with rack 2
export RACK_VERSION=2
bundle install

# Run tests
bundle exec rake

# Reset to original configuration
export RACK_VERSION=3
bundle install

The following environment variables are set to match the test matrix:

• REDIS_VERSION: latest
• RACK_VERSION: 3
• COVERAGE: 1

A Redis container runs as a sidecar service. From inside the container it is reachable at redis://redis:6379. The devcontainer also forwards port 6379 to your local machine, so you can connect via localhost:6379 from outside the container (e.g. with a Redis GUI).

To connect to Redis CLI from inside the container:

redis-cli -h redis

Note: the test suite spins up its own Redis instance on port 9736 — that is separate from this service.

Make sure the Redis container is running:

redis-cli -h redis ping

Should return PONG.

If you need to rebuild the container from scratch:

1. Run "Dev Containers: Rebuild Container" from the command palette
2. Or delete the container and volume manually:

   docker compose -f .devcontainer/docker-compose.yml down -v
