Generate Acceptance Test Skill

觸發時機

• analyze-frame 產生規格目錄後
• acceptance.yaml 更新時
• 需求異動需同步更新驗收測試時
• 代碼生成前，希望先鎖定可執行的驗收測試

核心任務

1. 解析 acceptance.yaml 的測試規格
2. 自動生成 ezSpec step definition（開發人員不需要手寫）
3. 維護規格與測試的一致性
4. 建立與 Frame Concerns 的可追溯連結

工具腳本 (scripts/)

generate_tests.py - 測試生成器

從 acceptance.yaml 生成各語言的 BDD 測試骨架。支援新格式 (acceptance_criteria) 和舊格式 (scenarios)。

使用方式：

# 生成 Gherkin .feature 檔案
python ~/.claude/skills/generate-acceptance-test/scripts/generate_tests.py \
    docs/specs/create-workflow/ --lang gherkin

# 生成 TypeScript Cucumber.js step definitions
python ~/.claude/skills/generate-acceptance-test/scripts/generate_tests.py \
    docs/specs/create-workflow/ --lang typescript --output tests/acceptance/

# 生成 Go Ginkgo 測試
python ~/.claude/skills/generate-acceptance-test/scripts/generate_tests.py \
    docs/specs/create-workflow/ --lang go --output tests/acceptance/

# 生成 Rust cucumber-rs 測試
python ~/.claude/skills/generate-acceptance-test/scripts/generate_tests.py \
    docs/specs/create-workflow/ --lang rust --output tests/acceptance/

支援語言：

格式相容性：

腳本自動偵測並支援兩種格式：

# 新格式 (推薦)
acceptance_criteria:
  - id: AC1
    trace:
      requirement: [CBF-REQ-1]
      frame_concerns: [FC1]
    given: ["..."]
    when: ["..."]
    then: ["..."]

# 舊格式 (向下相容)
acceptance:
  scenarios:
    - id: AT1
      given:
        - condition: "..."
      when:
        - action: "..."
      then:
        - expectation: "..."

關鍵概念

Executable Specification

• 驗收測試規格 = 可執行的規格
• 使用類似 Gherkin 的 given/when/then 語法
• AI 自動生成 step definition，開發人員不需要手寫
• 規格變更時，測試自動同步

ezSpec Java 生成（Fluent API）

AI 自動生成的 ezSpec 測試，開發人員不需要手寫 step definition：

// tests/acceptance/CreateWorkflowAcceptanceTest.java
// Auto-generated from acceptance.yaml

/**
 * AC1: Create a valid workflow successfully
 * Validates:
 * - then: workflow is created with correct boardId
 * - then: workflow is not deleted (isDeleted = false)
 * - then: workflow has no lanes/stages initially
 * - then: WorkflowCreated event is published
 */
@EzScenario(rule = SUCCESSFUL_CREATION_RULE)
public void should_create_workflow_successfully() {
    feature.newScenario()
        .Given("a user wants to create a workflow for a board", ScenarioEnvironment env -> {
            String workflowId = UUID.randomUUID().toString();
            String boardId = UUID.randomUUID().toString();
            String userId = "test-user";

            env.put("workflowId", workflowId)
               .put("boardId", boardId)
               .put("userId", userId)
               .put("name", "Development Workflow");
        })
        .When("the workflow is created", ScenarioEnvironment env -> {...})
        .ThenSuccess(ScenarioEnvironment env -> {...})
        .And("the workflow should be persisted with correct boardId", ScenarioEnvironment env -> {...})
        .And("the workflow should not be deleted", ScenarioEnvironment env -> {...})
        .And("the workflow should have no root stages initially", ScenarioEnvironment env -> {...})
        .And("a WorkflowCreated event should be published", ScenarioEnvironment env -> {
            await().atMost(timeout: 5, TimeUnit.SECONDS).untilAsserted(() -> {
                assertThat(notifyFakeHandleAllEventsService.getHandledEventsSize()).isEqualTo(expected: 1);
                assertThat(notifyFakeHandleAllEventsService.handledEventTimes(WorkflowEvents.WorkflowCreated.class)).isEqualTo(1);
            });

            WorkflowEvents.WorkflowCreated event = (WorkflowEvents.WorkflowCreated) notifyFakeHandleAllEventsService.getEvent(0);
            var input = env.get("input", CreateWorkflowInput.class);
            assertThat(event.workflowId().value()).isEqualTo(input.workflowId);

            assertThat(event.name()).isEqualTo(input.name);
        })
        .Execute();
}

ezSpec 生成規則

1. 方法命名：should{action}{outcome} 格式
2. JavaDoc 註解：包含 AC ID 和 Validates 項目
3. Fluent API：.Given() → .When() → .ThenSuccess() / .ThenFailure() → .And() → .Execute()
4. Lambda 環境：使用 ScenarioEnvironment 傳遞狀態
5. 事件驗證：使用 await().atMost() 處理非同步事件

boardId: "board-123" name: "Sprint 1" operatorId: "user-456"

- name: "invalidWorkflowInput" type: "CreateWorkflowInput" value: boardId: "" name: "" operatorId: "user-456"

## 同步檢查機制

當規格更新時，Skill 會：

1. **偵測變更**：比對 acceptance.yaml 的變更
2. **標記過時測試**：在 .feature 檔案中標記需更新的場景
3. **生成差異報告**：列出需要同步的項目

同步狀態報告

syncreport: generatedat: "2024-12-25T10:00:00Z"

in_sync: - AT1 - AT2

outofsync: - id: AT3 reason: "acceptance.yaml updated, feature file not regenerated" diff: "then clause changed"

missing: - id: AT4 reason: "New scenario added to acceptance.yaml"

---

## 品質檢查清單

- [ ] 每個 scenario 是否都有可執行的 Given/When/Then？
- [ ] 是否涵蓋 happy-path、error-case、edge-case？
- [ ] 是否與 Frame Concerns 建立 validates_concerns 連結？
- [ ] 是否與 contracts 建立 validates_contracts 連結？
- [ ] 測試名稱、檔名是否對應 feature-name？
- [ ] 併發場景是否有測試 (若 FC 包含 Concurrency)？

## BDD 框架支援

本 Skill 支援以下語言與 BDD 框架：

| 語言 | 框架 | 特點 |
|------|------|------|
| Java | ezSpec | Fluent API, 無需 step definition |
| Go | Ginkgo + Gomega | BDD 風格, 表格驅動測試 |

### TypeScript: Jest-Cucumber 替代方案

// tests/acceptance/create-workflow.spec.ts // Using jest-cucumber for tighter Jest integration

import { defineFeature, loadFeature } from 'jest-cucumber'; import { CreateWorkflowUseCase } from '@/application/use-cases/CreateWorkflowUseCase'; import { InMemoryWorkflowRepository } from '@/infrastructure/repositories/InMemoryWorkflowRepository'; import { MockEventPublisher } from '@/tests/mocks/MockEventPublisher'; import { MockAuthorizationService } from '@/tests/mocks/MockAuthorizationService';

const feature = loadFeature('./features/create-workflow.feature');

defineFeature(feature, (test) => { let repository: InMemoryWorkflowRepository; let eventPublisher: MockEventPublisher; let authService: MockAuthorizationService; let useCase: CreateWorkflowUseCase; let input: { boardId: string; name: string; operatorId: string }; let result: { workflowId: string } | null; let error: Error | null;

beforeEach(() => { repository = new InMemoryWorkflowRepository(); eventPublisher = new MockEventPublisher(); authService = new MockAuthorizationService(); useCase = new CreateWorkflowUseCase(repository, eventPublisher, authService); result = null; error = null; });

test('Create a valid workflow successfully', ({ given, and, when, then }) => { given(/^a boardId "(.*)" is provided$/, (boardId: string) => { input = { ...input, boardId }; });

and(/^a user "(.*)" is authorized to create workflows for that boardId$/, (userId: string) => { input = { ...input, operatorId: userId }; authService.allowCapability(userId, 'create_workflow', input.boardId); });

when(/^the user requests to create a workflow with name "(.*)"$/, async (name: string) => { input = { ...input, name }; try { result = await useCase.execute(input); } catch (e) { error = e as Error; } });

then('the request should succeed', () => { expect(error).toBeNull(); expect(result).not.toBeNull(); });

and(/^a Workflow should be created with name "(.*)"$/, async (name: string) => { const workflow = await repository.findById(result!.workflowId); expect(workflow?.name).toBe(name); });

and('a WorkflowCreated event should be published', () => { expect(eventPublisher.events).toHaveLength(1); expect(eventPublisher.events[0].type).toBe('WorkflowCreated'); }); }); });
