| description | E2E testing of kon using tmux sessions; IMPORTANT: only trigger this skill when user asks for e2e testing of kon |
End-to-end testing of kon using tmux sessions to programmatically control the TUI application.
Kon is a TUI (Textual-based) app. Running tests programmatically is hard. Tmux provides:
tmux new-session - isolate test environmenttmux send-keys - send keyboard inputtmux capture-pane - capture outputtmux has-session - check if kon is runningHOME=/tmp/kon-e2e-home so runtime settings do not mutate the real user config; auth JSON files are copied into the temp HOME when present so provider startup still works@, /, runtime pickers, keybindings) by checking UI elements appear/tmp/kon-test-project# Run all e2e tests from the repo root
bash .kon/skills/kon-tmux-test/run-e2e-tests.sh
# Optional: keep the temporary HOME for debugging
KEEP_E2E_HOME=1 bash .kon/skills/kon-tmux-test/run-e2e-tests.sh
# Optional: override launch command/provider/model
KON_CMD='uv run kon --model gpt-5.5' \
bash .kon/skills/kon-tmux-test/run-e2e-tests.sh
After running, read /tmp/kon-test-*.txt and evaluate the captured pane/config/filesystem outputs.
setup-test-project.shCreates a deterministic test project structure at /tmp/kon-test-project/.
bash .kon/skills/kon-tmux-test/setup-test-project.sh
run-e2e-tests.shRuns comprehensive e2e tests including UI triggers, runtime controls, tab completion, and tool execution.

Esc sends literal characters.Escape to dismiss completions, then C-u to clear text.Escape '[' 'Z' rather than relying on a tmux key name.Escape '[84;6u' because C-S-t often collapses to Ctrl+T.After running the test script, evaluate results by reading the output files.

After presenting the report, ALWAYS give the user this shell command so they can inspect raw captured outputs:
for f in /tmp/kon-test-*.txt; do printf "\n\033[1;36m▶▶▶ %s\033[0m\n" "$f"; awk 'NF{found=1} found{lines[++n]=$0} END{while(n>0 && lines[n]=="") n--; for(i=1;i<=n;i++) print lines[i]}' "$f"; done
# Test script auto-cleans tmux session and temp HOME unless KEEP_E2E_HOME=1.
# Output files remain for evaluation (/tmp/kon-test-*.txt).
# Manual cleanup if needed:
tmux kill-session -t kon-test 2>/dev/null
rm -rf /tmp/kon-test-project /tmp/kon-e2e-home
rm -f /tmp/kon-test-*.txt
# Session management
tmux new-session -d -s <name> -c <dir> '<command>'
tmux kill-session -t <name>
tmux has-session -t <name>
# Input — IMPORTANT: use full key names (Escape, Enter, not Esc)
tmux send-keys -t <name> "text"
tmux send-keys -t <name> Enter
tmux send-keys -t <name> Escape

KEEP_E2E_HOME=1 to inspect temp config/session files after failures./resume so there is a session with messages in the list.
