Linux Test

Linux Integration Test Runner

Overview

Some Freenet integration tests require Linux's full loopback range (127.x.x.x) and fail on macOS with "Can't assign requested address". This skill runs those tests inside a Docker container using the docker/test-runner/ infrastructure.

Arguments

• Test name only: /freenet:linux-test run_delegate_messaging_e2e — auto-wraps as cargo test with --nocapture
• Full cargo args: /freenet:linux-test cargo test -p freenet -- test_name — passed through directly
• No args: Show usage help and list known Linux-required tests

Known Linux-Required Tests

These tests bind multiple loopback addresses and need Linux:

Step 1: Parse Arguments

Determine the command to run inside Docker:

• No arguments provided: Display the usage help below and stop.

Usage: /freenet:linux-test <test_name_or_cargo_args>

Examples:
  /freenet:linux-test run_delegate_messaging_e2e
  /freenet:linux-test cargo test -p freenet -- test_name
  /freenet:linux-test cargo test -p freenet-ping-app --test run_app_blocked_peers -- --nocapture

Known Linux-required tests:
  - run_app_blocked_peers (freenet-ping-app)
  - run_delegate_messaging_e2e (freenet-ping-app)
  - run_app_delegate_wasmtime (freenet-ping-app)
  - edge_case_state_sizes (freenet)
  - error_notification (freenet)
  - connectivity tests (freenet)

• Starts with cargo: Use arguments as-is. Append -- --nocapture if no -- separator is present.
• Just a test name: Map to the appropriate cargo test command:
  • If the test name matches a known test above, use the correct package.
  • Otherwise, default to: cargo test -p freenet --test <name> -- --nocapture
  • For freenet-ping-app tests: cargo test -p freenet-ping-app --test <name> -- --nocapture

Step 2: Ensure Docker Image Exists

# Check if the image exists
docker image inspect freenet-test-runner >/dev/null 2>&1

If the image does NOT exist, build it:

docker build -t freenet-test-runner -f docker/test-runner/Dockerfile .

Tell the user: "Building Docker image freenet-test-runner (first time only, takes a few minutes)..."

Step 3: Run the Test

Execute the test using docker/test-runner/run.sh:

docker/test-runner/run.sh <command args>

Important: Use run_in_background for the Bash tool since tests can take several minutes. Set a generous timeout (600000ms / 10 minutes).

Step 4: Report Results

After the test completes:

• If exit code is 0: Report success with a summary of the output (test count, time taken).
• If exit code is non-zero: Report failure. Show the relevant error output (last ~50 lines). Look for panic messages, assertion failures, or compilation errors and highlight them.

Notes

• The first run after building the image will compile from scratch (~10-15 min). Subsequent runs use cached builds via Docker volumes.
• To reset cached builds: docker volume rm freenet-test-build freenet-test-target freenet-test-cargo
• Source is mounted read-only; the container rsyncs to a build volume for native Linux filesystem speed.
