linux-test

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:

| Test | Package | |------|---------| | 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 | | Tests in connectivity.rs | freenet |

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.
