前端测试

Execute CLI commands and tests inside the devcontainer. The host machine is macOS but the project binary is Linux — running CLI commands on the host will silently produce wrong results or fail. This skill prevents that mistake.

When to Use This

• Running ss / skillshare commands for verification
• Running go test, make test, make check
• Reproducing a bug report
• Testing a feature you just implemented
• Starting the web UI dashboard
• Any command that needs the skillshare binary or Go toolchain

When NOT to Use This

• Editing source code (do that on host via Read/Edit tools)
• Running git commands (git works on host)
• Running make fmt, make lint (host-safe Go toolchain commands; no container needed)
• E2E test runbooks → use cli-e2e-test skill instead (it handles ssenv isolation)

Architecture: Two Layers of Isolation

Host (macOS)
  └─ Devcontainer (Linux, Debian-based)
       ├─ Default HOME: /home/developer (persistent volume)
       ├─ Source: /workspace (bind-mount of repo root)
       └─ ssenv environments: ~/.ss-envs/<name>/ (isolated HOME dirs)

Devcontainer = Linux environment with Go, git, pnpm, air (hot-reload). Source code is at /workspace (bind-mount of the host repo). The ss / skillshare wrapper auto-builds from source on every invocation — no manual make build needed. Edit code on the host, then immediately docker exec to run it; the change is picked up automatically.

ssenv = Isolated HOME directories within the devcontainer. Each env gets its own ~/.config/skillshare/, ~/.claude/, etc. Use ssenv when you need a clean state (testing init, install, sync) without polluting the container's default HOME.

Zero-Rebuild Workflow

Source code is bind-mounted into the container at /workspace. The ss wrapper runs go build transparently on every invocation:

1. Edit files on host (Read/Edit tools)
2. docker exec $CONTAINER ss <command> — picks up your changes instantly
3. No make build, no restart, no rebuild step

This also applies to go test — tests always compile against the latest source. The Web UI backend uses air for hot-reload (same zero-rebuild experience).

Entering the Devcontainer

The quickest way — one command builds, initialises, and enters the shell:

make devc           # build + init + interactive shell (one step)
make devc-up        # start only (no shell)
make devc-down      # stop
make devc-restart   # restart + re-run start-dev.sh
make devc-reset     # full reset (remove volumes), then `make devc` to re-init
make devc-status    # show container status

Works with or without VS Code — make devc handles the full lifecycle autonomously.

Programmatic access (for docker exec workflows)

CONTAINER=$(docker compose -f .devcontainer/docker-compose.yml ps -q skillshare-devcontainer 2>/dev/null)

If $CONTAINER is empty, tell the user:

Devcontainer is not running. Start it with make devc-up.

Then verify the binary:

docker exec $CONTAINER bash -c \
  '/workspace/.devcontainer/ensure-skillshare-linux-binary.sh && ss version'

Running Commands

Simple command (uses container's default HOME)

docker exec $CONTAINER ss <command> [flags]

Good for: ss version, ss status, ss list, ss check, ss audit.

Command with isolated HOME (clean state)

ENV_NAME="test-$(date +%s)"
docker exec $CONTAINER ssenv create "$ENV_NAME" --init
docker exec $CONTAINER ssenv enter "$ENV_NAME" -- ss status
# Cleanup when done:
docker exec $CONTAINER ssenv delete "$ENV_NAME" --force

Good for: testing init, install, sync, uninstall — anything that modifies config/state.

Multi-command sequence

docker exec $CONTAINER ssenv enter "$ENV_NAME" -- bash -c '
  ss install runkids/demo-skills --track --force
  ss list
  ss sync
'

Always use bash -c '...' for multi-command sequences inside ssenv enter.

Go tests

# All tests (unit + integration)
docker exec $CONTAINER bash -c 'cd /workspace && make test'

# Unit tests only
docker exec $CONTAINER bash -c 'cd /workspace && make test-unit'

# Integration tests only
docker exec $CONTAINER bash -c 'cd /workspace && make test-int'

# Specific test
docker exec $CONTAINER bash -c 'cd /workspace && go test ./tests/integration -run TestInit_Fresh -count=1'

# Specific package
docker exec $CONTAINER bash -c 'cd /workspace && go test ./internal/install/... -count=1'

Always cd /workspace before Go commands — ssenv changes HOME which can break module resolution.

Go tests with auth disabled

Some tests (e.g., TestResolveToken, TestAuthEnv) need auth credentials removed:

docker exec $CONTAINER bash -c '
  eval "$(credential-helper --eval off)"
  cd /workspace
  go test ./internal/github -run TestResolveToken -count=1
  eval "$(credential-helper --eval on)"
'

Web UI Dashboard

# Start (global mode)
docker exec $CONTAINER ui

# Start (project mode — uses ~/demo-project)
docker exec $CONTAINER ui -p

# Stop
docker exec $CONTAINER ui stop

Dashboard accessible at http://localhost:5173 (Vite dev server with HMR). API backend at http://localhost:19420. Logs: /tmp/api-dev.log, /tmp/vite-dev.log.

ssenv Quick Reference

For automation (non-interactive), prefer ssenv enter <name> -- <command> over ssnew/ssuse (which launch subshells).

Ports

Common Mistakes to Avoid

1. Running ss on host — macOS binary won't match Linux container; always docker exec
2. Forgetting cd /workspace — Go tests fail if HOME was changed by ssenv
3. Using make test on host — builds macOS binary, then tests run against wrong arch
4. Skipping --init on ssenv create — env won't have config; most commands will fail
5. Not cleaning up ssenv — ssenv delete <name> --force after done; or ask user
6. Running from /workspace root without -g — the ss wrapper auto-redirects to ~/demo-project in project mode; use -g for global or set SKILLSHARE_DEV_ALLOW_WORKSPACE_PROJECT=1
7. Running make build before testing — unnecessary; the ss wrapper auto-builds from source every time

Rules

• All CLI execution inside devcontainer — no exceptions
• Use ssenv for stateful tests — don't pollute default HOME
• Always verify — run the command and check output; never assume it worked
• Clean up — delete ssenv environments after use (or ask user)
• Report container ID — set $CONTAINER at the start and reuse throughout
