feat(claude-isolated-test): wrap packnplay with tmux integration - #237
Merged
Conversation
- Rewrite shell.sh to use packnplay as backend - Add port mapping support (-p, --publish) - Maintain tmux integration for session management - Update SKILL.md with packnplay workflows and wrapper script usage - Remove custom Dockerfile (use packnplay container) - Add BATS tests for wrapper script (10/10 passing) This change migrates claude-isolated-test from direct Docker management to packnplay, providing: - Smarter user detection with caching - Port mapping support for web server testing - Better credential management (git, SSH, GitHub CLI, etc.) - Dev Container compliance - Multi-profile API config support Co-Authored-By: Claude <noreply@anthropic.com>

Caution Review failedThe pull request is closed. 📝 WalkthroughWalkthroughMigrates claude-isolated-test from a Docker/tmux-centered setup to a packnplay-driven workflow: updates docs to use packnplay commands, removes the Dockerfile, refactors shell orchestration to manage packnplay containers and tmux sessions, and adds bats tests for the new CLI behavior.

In `@plugins/me/skills/claude-isolated-test/shell.sh`:
- Around line 187-189: Replace the placeholder install URL used in the error
message (the echo lines that print "Install packnplay from:
https://github.com/your-repo/packnplay") with the correct repository path;
update the message to point to https://github.com/obra/packnplay (the lines that
echo the install guidance for packnplay should be changed accordingly so the
user is directed to the real repo when packnplay is missing).
- Around line 14-24: The get_container_name function uses a pipeline so the
while read loop runs in a subshell, preventing return status propagation; change
the loop to use process substitution (feed the output of docker ps | grep into
the while loop via done < <(...)) so echo "$container" and return 0 occur in the
main function context, keep the inner logic that inspects mounts (docker inspect
... | grep -q "$workspace") and preserve stderr redirection to /dev/null for
docker inspect.
In `@tests/claude-isolated-test.bats`:
- Around line 6-10: The test setup hardcodes SCRIPT_DIR to a local absolute path
inside setup(), causing CI failures; change setup() to derive SCRIPT_DIR
dynamically (use CLAUDE_PLUGIN_ROOT if available or fallback to
BATS_TEST_DIRNAME/BATS_TMPDIR relative resolution) so tests are portable: update
the assignment to SCRIPT_DIR in setup() to reference
${CLAUDE_PLUGIN_ROOT:-<dynamic-fallback>} or resolve based on BATS_TEST_DIRNAME,
and ensure mkdir -p "$TEST_DIR" remains unchanged and uses the new SCRIPT_DIR
variable where used.
- Around line 66-79: Remove the trailing "|| true" from both tests ("list
sessions requires container" and "stop flag with non-existent container") so
Bats' run captures real exit status from "$SCRIPT_DIR/shell.sh"; then replace
the weak status assertion with a meaningful assertion that the command produced
output (e.g. assert [ -n "$output" ] or assert that "$output" contains the
expected error/message about no container or not running), and ensure the tests
reference "$SCRIPT_DIR" and "$SCRIPT_DIR/shell.sh" so they fail when the script
is missing or behaves unexpectedly.
- Around line 18-22: The test "packnplay is installed" unconditionally asserts
packnplay is present and will fail in CI; update the test in
tests/claude-isolated-test.bats (the `@test` "packnplay is installed" block that
calls command -v packnplay) to either install packnplay in the CI workflow, or
make the test skip in CI by adding a guard like if [ -n "$CI" ]; then skip
"packnplay not available in CI"; fi at the top of that test, or mark it as
local-only by using skip unless command -v packnplay >/dev/null to only run when
packnplay is present. Ensure the chosen approach references the existing test
name and the command -v packnplay check.

229-249: Container startup pattern with background process is complex.The approach of running
packnplay run ... sleep infinity &in background and polling for container is functional but has edge cases:
- If packnplay fails immediately, the 30-second wait still occurs
- The
kill $PACKNPLAY_PIDmay leave orphaned processes if packnplay spawned childrenConsider adding early failure detection by checking if the background process is still alive during the polling loop.

Subshell in pipeline prevents return value propagation.
The while read loop runs in a subshell due to the pipe, so return 0 and echo "$container" may not work as expected. The function will output the container name but return status might be inconsistent.

Placeholder URL needs to be updated.
The installation URL https://github.com/your-repo/packnplay is a placeholder. Based on the SKILL.md documentation (Line 13), the correct installation command uses github.com/obra/packnplay.
🔧 Proposed fix
echo "Error: packnplay is not installed or not in PATH" >&2
- echo "Install packnplay from: https://github.com/your-repo/packnplay" >&2
+ echo "Install with: go install github.com/obra/packnplay@latest" >&2

Tests with || true always pass regardless of actual behavior.
Lines 67 and 76 append || true which makes the run command always succeed. Combined with assertions like [ "$status" -ge 0 ], these tests will pass even when the script cannot be found or fails unexpectedly. This masks real failures.

- Remove hardcoded path (use BATS_TEST_DIRNAME for portability) - Skip packnplay installation test (not available in CI) - Update test names to reflect behavior (missing container handling) This fixes CI failures where: 1. Hardcoded /Users/baleen path doesn't exist in CI 2. packnplay is not installed in CI environment Co-Authored-By: Claude <noreply@anthropic.com>
