QA Planning

QA Planning Skill

Generate the QA Contract - exhaustive Gherkin BDD scenarios (G#N) for all data sources and acceptance criteria (AC#N) for frontend. This contract is consumed by Plan Mode and verified by qa-commit skill.

When to Use

• During Ask mode Phase 2 (CONVERGE) for any feature work
• Before implementation to define testable acceptance criteria
• When documenting expected behavior for QA team

Output: QA Contract

The QA Contract is the primary artifact, consisting of:

• G#1, G#2, ... - Numbered Gherkin scenarios (backend/data)
• AC#1, AC#2, ... - Numbered acceptance criteria (frontend)

These IDs are referenced in Plan Mode's Commit Plan (Satisfies field) and verified by qa-commit skill.

Instructions

Phase 0: Identify ALL Data Sources (CRITICAL)

STOP. Before writing any Gherkin, exhaustively map ALL data sources for the feature.

Categorize each data source:

Data Source Inventory Template:

## Data Source Inventory

### Runtime APIs
| Endpoint | Method | Auth | Resource | Status |
|----------|--------|------|----------|--------|
| `/v1/resource` | GET | Yes | Resource | Existing |
| `/public/resource` | GET | No | Resource | New |

### Build-time Static
| Output Path | Source | Generator | Content |
|-------------|--------|-----------|---------|
| `/components.json` | Codebase | Build script | Component metadata |
| `/charts/[slug].json` | Codebase | Build script | Chart config + examples |

### Database Queries
| Query | Source | Auth | Purpose |
|-------|--------|------|---------|
| `connectors` | Hasura | Yes | List connectors |

### Middleware
| Route | Behavior | Auth |
|-------|----------|------|
| `developers.*` | Rewrite to public routes | Skip |

### External APIs
| Service | Endpoint | Purpose |
|---------|----------|---------|
| (none for this feature) | | |

Validation: Count total data sources. If < 3 for a non-trivial feature, you likely missed something. Re-examine the feature scope.

Phase 2: Define Pre-conditions Matrix (Given)

For each service, treat it as a black box. Based on the contract interface or data model, list all pre-condition parameters:

### [Method] [Path] Pre-conditions

| Parameter | Type | Source | Possible Values |
|-----------|------|--------|-----------------|
| `Authorization` | header | request | valid_token, invalid_token, expired_token, missing |
| `id` | path | URL | existing_uuid, non_existing_uuid, malformed, deleted |
| `status` | query | URL | enum values from data model |
| `[field]` | body | JSON | valid, null, empty, wrong_type, too_long |

Sources:

• header: Authorization, Content-Type, custom headers
• path: URL parameters (:id, :slug)
• query: Query string filters, pagination
• body: Request payload fields

Phase 3: Map When (Method + Path)

Each scenario has exactly ONE action:

When [METHOD] [/path/to/resource]

Examples:

• When GET /v1/connectors
• When POST /v1/connectors
• When GET /v1/connectors/{id}
• When DELETE /v1/connectors/{id}

Phase 4: Define Then (Response Contract)

Specify expected response object. Response varies based on pre-conditions:

Then status [code]
And response.[field] is [type]
And response.[field] equals [value]
And response.[field] in [array of valid values]
And response does NOT include [sensitive_field]

Response Schema Template:

// Success response
{
  data: {
    type: string,
    id: UUID,
    attributes: { ... }
  },
  meta?: { count: number }
}

// Error response
{
  error: {
    code: "NOT_FOUND" | "UNAUTHORIZED" | "VALIDATION_ERROR",
    message: string
  }
}

Phase 5: Write Gherkin Scenarios (G#N)

For each method+path, write scenarios covering all pre-condition combinations:

Feature: [Resource] API

  @G#1
  Scenario: G#1.1 - [Method] [path] - happy path
    Given Authorization header is "Bearer valid_token"
    And [pre-condition 1]
    And [pre-condition 2]
    When [METHOD] [/path]
    Then status 200
    And response.data.id is UUID
    And response.data.attributes.[field] is [type]

  @G#2
  Scenario: G#1.2 - [Method] [path] - missing auth
    Given no Authorization header
    When [METHOD] [/path]
    Then status 401
    And response.error.code equals "UNAUTHORIZED"

  @G#3
  Scenario: G#1.3 - [Method] [path] - not found
    Given Authorization header is "Bearer valid_token"
    And id is "non_existing_uuid"
    When [METHOD] [/path/{id}]
    Then status 404
    And response.error.code equals "NOT_FOUND"

Numbering Convention:

• G#N = Feature-level ID (G#1, G#2...)
• G#N.M = Scenario within feature (G#1.1, G#1.2...)
• Use @G#N tag for traceability

Coverage Matrix per Endpoint:

Phase 6: Build-time Static Scenarios (G#N)

For build-time generated data, write scenarios verifying the build script:

Pre-conditions for Build Scripts:

Template:

Feature: [Resource] Build Extraction

  @G#N
  Scenario: G#N.1 - Extract [resource] with complete metadata
    Given [source file] exists at [path]
    And [source file] has valid [structure]
    And [metadata fields] are documented
    When build script runs
    Then [output.json] includes [resource] entry
    And entry has [required fields]

  @G#N
  Scenario: G#N.2 - Skip internal/private [resources]
    Given [source file] has underscore prefix
    When build script runs
    Then [output.json] does NOT include entry

  @G#N
  Scenario: G#N.3 - Handle missing optional fields
    Given [source file] exists
    And [optional field] is not documented
    When build script runs
    Then entry has [optional field] as null

Coverage Matrix for Build Scripts:

Phase 7: Middleware/Routing Scenarios (G#N)

For middleware and routing logic:

Pre-conditions:

Template:

Feature: Hostname Routing

  @G#N
  Scenario: G#N.1 - Route [subdomain] to [target]
    Given Host header is "[subdomain].domain.com"
    And path is "[path]"
    When request arrives at middleware
    Then rewrite to [target route group]
    And [skip/require] authentication

  @G#N
  Scenario: G#N.2 - Unknown subdomain redirect
    Given Host header is "unknown.domain.com"
    When request arrives at middleware
    Then redirect to [default domain]

Phase 8: Frontend QA (Acceptance Criteria - AC#N)

For each UI component/screen, define numbered testable criteria using AC#N format:

Numbering Rules:

• Use sequential IDs: AC#1, AC#2, AC#3...
• IDs are feature-scoped (reset for each feature)
• Include ID in first column for traceability

Data Source Mapping for AC: Each AC must indicate which data source it consumes:

Phase 9: Integration Points

Identify cross-cutting concerns:

Phase 11: Artifact Validation (Poka-Yoke)

Before Gate transition, validate artifacts silently. Only show output if validation fails.

Gate 1 Validation (DIVERGE -> CONVERGE)

Check:

• All wireframes have status (OK/KO/DIG, or no comment = OK)
• No orphan references (#{N} mentioned but not defined)
• At least 1 wireframe validated (OK)

Gate 2 Validation (CONVERGE -> PLAN)

Check:

• QA Contract has at least 1 G#N (Gherkin scenario)
• QA Contract has at least 1 AC#N (acceptance criteria)
• Each phase has at least 1 commit planned
• No circular dependencies in phasing order
• All G#N and AC#N are assigned to phases

Validation Output

If all pass: (silent, no output - proceed normally)

If validation fails:

R | [Feature] | VALIDATION ERROR
---
Cannot proceed to [NEXT_PHASE]:
- [Missing: wireframe #4 has no status]
- [Missing: QA Contract needs at least 1 G#N]

Fix: [Specific action to resolve]

Integration

This validation runs automatically before:

• Gate 1 presentation (ask.mdc Phase 1 - DIVERGE)
• Gate 2 presentation (ask.mdc Phase 2 - CONVERGE)
