testland/bug-bash-facilitator

Builds a structured bug-bash session - pre-bash kit (charter, test-data prep, environment setup, sign-up sheet), in-bash structure (role rotation across cohorts, shared backlog board, real-time triage), scoring rubric (severity weighting, novelty bonus), and a post-bash same-day wrap-up authored by the facilitator (not a standalone debrief: for post-session writeups without a live bash, use manual-test-debrief). Use when a team needs a coordinated multi-tester sweep before a release or after a major change - converts an ad-hoc "everyone test for an hour" into a recorded, comparable session with deliverables.

Overview

An unfacilitated bug bash is "everyone clicks around for an hour and we hope something turns up." The result: lots of duplicates, no triage, debrief skipped, no record.

A facilitated bug bash is a structured exploratory session at team scale - multiple testers in coordinated cohorts, shared backlog visible to all, triage in real-time, debrief that produces follow-ups.

This skill builds the kit + structure + scoring + debrief.

When to use

Pre-release: a final before-prod sweep across the whole team.
Post-major-change: after a refactor / migration / new platform integration.
Quarterly: a scheduled "everyone tests for 90 min" cadence.
New-tester onboarding: bug-bash as the team's first introduction for new joiners.

If the goal is a single tester running a charter, author a single exploratory charter directly. Bug bashes are the multi-tester / scaled version.

Step 1 - Pre-bash kit (1 week before)

# Bug bash - `<release / feature / area>`

**Date:** YYYY-MM-DD
**Time:** 14:00-15:30 (90 min)
**Environment:** staging.example.com (build `v1.4.5-rc1`)
**Facilitator:** _______________
**Note-taker:** _______________

## Mission

Find regressions, edge cases, and usability issues in the new
checkout flow before the release on YYYY-MM-DD.

## Charters (5 cohorts × 90 min)

Per cohort, 1-2 testers + 1 facilitator-roving:

- **Cohort A - Money:** Apply the Money tour
  across the new checkout discount + tax flow - visit every place
  money / pricing / currency / discount appears and verify each;
  hunts rounding errors, currency-conversion drift, discount
  stacking, free-shipping edges, locale formatting (€1.234,56 vs
  $1,234.56).
- **Cohort B - Bad data:** Apply the Bad-data tour
  across promo code input, address fields, payment fields - feed
  pathological inputs (empty, single space, 5000 chars, SQL
  injection, XSS, unicode bidi override, RTL text, emoji ZWJ
  sequences, null byte) and observe validation + error handling.
- **Cohort C - Configuration:** Vary user state (new vs existing
  account, EU vs US user, mobile vs desktop) and re-run hero flows.
- **Cohort D - Landmark:** Walk the canonical hero flow (search →
  add to cart → checkout → confirmation) under various conditions.
- **Cohort E - Garbage collector:** Visit every page in the
  checkout funnel; flag 404s, broken images, stale strings.

## Test data prep (do BEFORE the bash)

- [ ] Create 5 test accounts with varying states (per
      `synthetic-data-tool-selector`):
      `qa-bash-A`, `qa-bash-B`, ..., `qa-bash-E`.
- [ ] Seed promo codes: `WELCOME10`, `EXPIRED50`, `MIN100`,
      `STACKABLE5`.
- [ ] Pre-fund the Stripe test account; expose test cards
      (Stripe test card list).
- [ ] Verify staging is at the right SHA; tag artifact.

## Sign-up sheet

| Cohort | Tester(s)         | Notes |
|--------|-------------------|-------|
| A      |                   |       |
| B      |                   |       |
| ...    |                   |       |

The kit is sent 1 week before so testers can prepare and team members can RSVP. Testers who can't attend live get an async-charter version.

Step 2 - In-bash structure

14:00-14:05  Kickoff (facilitator presents the mission, charters, scoring rubric)
14:05-14:50  Round 1 (each cohort runs its charter; ~45 min)
14:50-15:00  Mid-bash huddle (5-min check-in: what's everyone seeing?)
15:00-15:25  Round 2 (cohorts swap charters; new lens on the same area)
15:25-15:30  Wrap (everyone logs final bugs; facilitator closes the board)

The cohort swap at the midpoint is critical - it's the same testers looking at the area through a fresh lens, and it surfaces bugs that the first cohort's tour missed.

Step 3 - Shared backlog board

A shared spreadsheet / Notion table / GitHub issues view that everyone can see live during the bash:

ID	Time	Cohort	Reporter	Title	Severity	Repro	Triage	Owner	Final disposition
1	14:08	A	Alice	Promo `WELCOME10` not applied	high	Cart `BOOK-001`; apply code	bug	Bob	BUG-987
2	14:12	B	Bob	Promo input accepts SQL injection	high	Type `'; DROP--` and apply	bug	Bob	BUG-988
3	14:15	A	Alice	Subtotal off by 1 cent on $24.99 + 10%	low	Apply WELCOME10 to $24.99	bug	Carol	BUG-989
4	14:20	C	Carol	EU user sees $ symbol instead of €	medium	Set locale=EU; checkout	bug	Dave	BUG-990

The Triage column is filled in real-time by a roving facilitator who decides:

bug: confirmed reproducible defect.
dup: duplicate of another row.
spike: needs a research session (architectural concern, not a fixable defect).
quirk: known trade-off or won't-fix; document and close.
tbd: needs more investigation.

Real-time triage prevents the debrief from being a giant classification exercise.

Step 4 - Scoring rubric

Optional but motivating: a points system.

Finding type	Points
Critical (data loss, P0)	10
High (broken flow)	5
Medium (degraded UX)	3
Low (cosmetic / minor)	1
Novel (no one else thought to check)	+2 bonus
Cluster lead (the first row in a 3+-row cluster)	+1 bonus
Duplicate (already on board)	0

Tally per cohort + per individual at the wrap. The points are explicitly fun, not performance review - but they motivate testers to go beyond the obvious.

Step 5 - Post-bash debrief

Within 24 hours, the facilitator + note-taker produce:

## Bug bash debrief - `<release>`

**Date:** YYYY-MM-DD
**Participants:** N (across 5 cohorts)
**Duration:** 90 min

### Findings summary

| Severity   | Count | Notes |
|------------|------:|-------|
| Critical   |     0 |       |
| High       |     6 | 4 cluster (promo flow); 2 isolated (config) |
| Medium     |    14 |       |
| Low        |    23 | mostly cosmetic / copy issues |
| **Total**  |    43 |       |

### Cluster analysis

| Cluster                | Bugs | Bug IDs                | Owner    | Action |
|------------------------|-----:|------------------------|----------|--------|
| Promo apply edge cases  |    7 | BUG-987, 988, 989, 990, 991, 992, 993 | Bob | Block release until fixed. |
| EU locale bugs           |    3 | BUG-994, 995, 996       | Dave | Fix in current sprint. |
| Cosmetic / copy          |   12 | (per-bug)               | Eve  | Backlog; address over the next 2 sprints. |

### Cohort scoring (per Step 4)

| Cohort | Findings | Points | Top finder |
|--------|---------:|-------:|------------|
| A      |       12 |     34 | Alice (BUG-987 high + 2 cluster lead bonuses) |
| B      |        9 |     27 | Bob (SQL injection - high + novelty) |
| ...    |          |        |            |

### Process retrospective

### Action items

- [ ] Bob: fix BUG-987 cluster within 48h (release blocker).
- [ ] Dave: fix EU locale cluster in current sprint.
- [ ] Eve: backlog the 12 cosmetic items for grooming.
- [ ] Facilitator: schedule next bash for `v1.5.0` release.

Step 6 - Async participants

Team members who can't attend live get a mini-charter to run solo within the same week:

# Async bug bash mini-charter - `<release>` (cohort: pick one)

You missed the live bash; here's the 30-min version. Pick a
cohort that wasn't done yet (or revisit one with a new lens).

(charter cohort body)

When done, log findings to the same shared board with
`async` tag.

Async participation isn't ideal (no roving facilitator, no live triage) but it broadens coverage.

Anti-patterns

Anti-pattern	Why it fails	Fix
Open-ended "everyone test for an hour"	Heavy duplication; no coverage map; debrief skipped.	Cohorts + charters (Step 1).
No real-time triage	Debrief becomes a 3-hour classification exercise.	Roving facilitator triages live (Step 3).
Scoring as performance review	Testers chase points, miss high-value bugs.	Scoring is for fun + motivation; explicit "not performance" disclaimer.
Bug bash without test-data prep	Testers spend half the time creating accounts.	Pre-prep test data 1 week ahead (Step 1).
Same-cohort assignments quarter after quarter	Same testers find the same bugs.	Rotate assignments; mid-bash cohort swap (Step 2).
Post-bash with no follow-up actions	Bugs sit in the backlog; team disillusioned by next bash.	Action items per cluster owner (Step 5).
Running the bash on a stale build	Bugs found are already-fixed; testers waste time.	Tag the build SHA; verify staging is current.

Limitations

High coordination cost. A bug bash is 90 min of testing × N testers + 1-2 hours facilitator prep + 30 min debrief authoring. Don't run weekly; ~quarterly is the right cadence for most teams.
Findings depend on coverage. Cohorts cover what's assigned; gaps invisible. Pair with automated regression for known shapes.
Doesn't replace per-feature exploratory. A bash hits breadth; per-feature exploratory hits depth. Both have a place.
Async less effective than live. Without live triage and the cohort swap, async finds fewer bugs per hour.
