  def caveats
    <<~EOS
      kportal requires:
        • kubectl installed and configured
        • Access to a Kubernetes cluster
        • A valid kubeconfig file (~/.kube/config)

      Quick start:
        1. Create a configuration file: .kportal.yaml
        2. Add your port-forward definitions
        3. Run: kportal

      For configuration examples and full documentation:
        https://lukaszraczylo.github.io/kportal

      To validate your configuration:
        kportal --check
    EOS
  end

  test do
    # Test that binary runs and reports correct version
    assert_match version.to_s, shell_output("#{bin}/kportal --version")

    # Test that binary can validate an empty config (should fail gracefully)
    (testpath/".kportal.yaml").write <<~YAML
      contexts:
        test:
          namespaces:
            default:
              - resource: test-pod
                port: 8080
                local_port: 8080
    YAML

    # Should be able to validate config even without kube access
    system bin/"kportal", "--check", "-c", testpath/".kportal.yaml"
  end
