概述

GitButler作为一款现代化的Git分支管理工具,采用了全面的测试策略来确保代码质量和用户体验。该项目基于Tauri框架构建,结合Rust后端和Svelte/TypeScript前端,测试策略覆盖了从单元测试到端到端测试的完整生命周期。

测试金字塔架构

GitButler的测试策略遵循经典的测试金字塔模型:

mermaid

单元测试策略

Rust后端单元测试

GitButler的后端采用Rust编写,单元测试主要针对核心业务逻辑:

// 示例:虚拟分支管理测试
#[cfg(test)]
mod tests {
    use super::*;
    
    #[test]
    fn test_virtual_branch_creation() {
        let mut repo = TestRepository::new();
        let branch_manager = BranchManager::new(&repo);
        
        // 创建虚拟分支
        let branch = branch_manager.create_branch("feature/test");
        assert!(branch.is_ok());
        assert_eq!(branch.unwrap().name, "feature/test");
    }
    
    #[test]
    fn test_change_assignment_to_branch() {
        let mut repo = TestRepository::new();
        let branch_manager = BranchManager::new(&repo);
        
        // 创建文件修改
        repo.create_file("test.txt", "content");
        
        // 将修改分配到分支
        let result = branch_manager.assign_changes_to_branch("feature/test");
        assert!(result.is_ok());
    }
}

TypeScript前端单元测试

前端使用Vitest进行单元测试,主要测试组件逻辑和状态管理:

// 示例:分支列表组件测试
import { describe, it, expect } from 'vitest';
import { render } from '@testing-library/svelte';
import BranchList from './BranchList.svelte';

describe('BranchList Component', () => {
  it('should display empty state when no branches', () => {
    const { getByText } = render(BranchList, { branches: [] });
    expect(getByText('No branches available')).toBeInTheDocument();
  });
  
  it('should render branch items correctly', () => {
    const branches = [
      { name: 'main', isCurrent: true },
      { name: 'feature/test', isCurrent: false }
    ];
    
    const { getByText } = render(BranchList, { branches });
    expect(getByText('main')).toBeInTheDocument();
    expect(getByText('feature/test')).toBeInTheDocument();
  });
});

集成测试策略

Rust集成测试

GitButler使用专门的测试支持crate (gitbutler-testsupport)来提供测试基础设施:

测试工具用途示例
TestRepository创建临时Git仓库测试分支操作
TestProject模拟完整项目环境测试文件监控
MockGit模拟Git操作测试Git集成
// 集成测试示例:分支同步功能
#[test]
fn test_branch_synchronization() {
    let test_repo = TestRepository::new();
    let remote_repo = TestRepository::new();
    
    // 配置远程仓库
    test_repo.add_remote("origin", remote_repo.path());
    
    let sync_manager = SyncManager::new(&test_repo);
    let result = sync_manager.sync_branch("feature/test");
    
    assert!(result.is_ok());
    assert!(remote_repo.has_branch("feature/test"));
}

前端集成测试

前端集成测试使用Testing Library来测试组件交互:

// 分支创建表单集成测试
import { fireEvent, render, waitFor } from '@testing-library/svelte';

describe('BranchCreateForm Integration', () => {
  it('should create branch and update list', async () => {
    const { getByLabelText, getByText, queryByText } = render(BranchCreateForm);
    
    // 填写分支名称
    const input = getByLabelText('Branch name');
    await fireEvent.input(input, { target: { value: 'new-feature' } });
    
    // 提交表单
    const submitButton = getByText('Create Branch');
    await fireEvent.click(submitButton);
    
    // 验证新分支显示
    await waitFor(() => {
      expect(queryByText('new-feature')).toBeInTheDocument();
    });
  });
});

E2E端到端测试

Playwright测试套件

GitButler使用Playwright进行跨平台的E2E测试:

// e2e/playwright/tests/branches.spec.ts
import { test, expect } from '@playwright/test';

test.describe('Branch Management', () => {
  test('should create and switch branches', async ({ page }) => {
    // 启动应用
    await page.goto('http://localhost:1420');
    
    // 创建新分支
    await page.click('button[aria-label="Create branch"]');
    await page.fill('input[placeholder="Branch name"]', 'test-branch');
    await page.click('text=Create');
    
    // 验证分支创建成功
    await expect(page.locator('text=test-branch')).toBeVisible();
    
    // 切换回main分支
    await page.click('text=main');
    await expect(page.locator('text=Current branch: main')).toBeVisible();
  });
  
  test('should show branch differences', async ({ page }) => {
    // 创建测试文件修改
    await page.click('button[aria-label="New file"]');
    await page.fill('#filename', 'test.txt');
    await page.fill('#content', 'Hello GitButler!');
    await page.click('text=Save');
    
    // 验证更改显示
    await expect(page.locator('text=Uncommitted changes')).toBeVisible();
    await expect(page.locator('text=test.txt')).toBeVisible();
  });
});

Blackbox测试

Blackbox测试使用WebDriverIO进行更底层的自动化测试:

// e2e/blackbox/tests/add-project.spec.ts
describe('Project Management', () => {
  it('should add existing Git repository', () => {
    const projectPath = '/tmp/test-repo';
    
    // 初始化测试仓库
    browser.executeScript(`
      mkdir -p ${projectPath}
      cd ${projectPath}
      git init
      echo "test" > README.md
      git add .
      git commit -m "Initial commit"
    `);
    
    // 通过UI添加项目
    $('button=Add Project').click();
    $('input[type="file"]').setValue(projectPath);
    $('button=Confirm').click();
    
    // 验证项目添加成功
    expect($('text=test-repo')).toBeDisplayed();
  });
});

测试基础设施

测试环境配置

GitButler提供了完整的测试环境配置:

// Playwright配置文件
// e2e/playwright/playwright.config.ts
import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  testDir: './tests',
  timeout: 30000,
  expect: {
    timeout: 5000
  },
  fullyParallel: true,
  forbidOnly: !!process.env.CI,
  retries: process.env.CI ? 2 : 0,
  workers: process.env.CI ? 1 : undefined,
  reporter: 'html',
  
  use: {
    baseURL: 'http://localhost:1420',
    trace: 'on-first-retry',
    screenshot: 'only-on-failure'
  },
  
  projects: [
    {
      name: 'chromium',
      use: { ...devices['Desktop Chrome'] }
    },
    {
      name: 'firefox',
      use: { ...devices['Desktop Firefox'] }
    },
    {
      name: 'webkit',
      use: { ...devices['Desktop Safari'] }
    }
  ],
  
  webServer: {
    command: 'pnpm dev:desktop',
    url: 'http://localhost:1420',
    reuseExistingServer: !process.env.CI,
    timeout: 120000
  }
});

测试数据管理

// 测试数据工厂模式
// crates/gitbutler-testsupport/src/test_project.rs
pub struct TestProjectBuilder {
    repo: TestRepository,
    files: Vec<TestFile>,
    branches: Vec<String>,
}

impl TestProjectBuilder {
    pub fn new() -> Self {
        Self {
            repo: TestRepository::new(),
            files: Vec::new(),
            branches: Vec::new(),
        }
    }
    
    pub fn with_file(mut self, path: &str, content: &str) -> Self {
        self.files.push(TestFile::new(path, content));
        self
    }
    
    pub fn with_branch(mut self, name: &str) -> Self {
        self.branches.push(name.to_string());
        self
    }
    
    pub fn build(self) -> TestProject {
        // 实现构建逻辑
        TestProject::from_builder(self)
    }
}

持续集成流水线

GitButler的CI/CD流水线包含完整的测试阶段:

CI配置要点

# GitHub Actions测试配置示例
name: Test Suite

on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4
    
    - name: Setup Rust
      uses: actions-rs/toolchain@v1
      with:
        toolchain: stable
        override: true
    
    - name: Setup Node.js
      uses: actions/setup-node@v3
      with:
        node-version: '20'
        cache: 'pnpm'
    
    - name: Install dependencies
      run: pnpm install
    
    - name: Run Rust tests
      run: cargo test --all --no-fail-fast
    
    - name: Run TypeScript tests
      run: pnpm test
    
    - name: Run E2E tests
      run: pnpm test:e2e
      env:
        CI: true

测试最佳实践

1. 测试隔离性

每个测试都应该独立运行,不依赖外部状态:

#[test]
fn test_isolated_branch_operations() {
    // 使用独立的测试仓库
    let test_repo = TestRepository::new();
    let test_branch = "test-isolated";
    
    // 测试操作
    let result = create_and_verify_branch(&test_repo, test_branch);
    assert!(result.is_ok());
    
    // 清理:测试框架自动处理
}

2. 测试数据工厂

使用构建器模式创建测试数据:

// 测试数据工厂
const createTestBranch = (overrides = {}) => ({
  name: 'test-branch',
  isCurrent: false,
  commits: [],
  files: [],
  ...overrides
});

// 使用工厂
const branch = createTestBranch({
  name: 'feature/new',
  commits: [{ message: 'Initial commit' }]
});

3. 异步测试处理

正确处理异步操作和超时:

test('should handle async branch operations', async () => {
  const { page } = await setupTest();
  
  // 使用适当的等待策略
  await page.click('button[aria-label="Sync branches"]');
  await page.waitForSelector('.sync-complete', { timeout: 10000 });
  
  expect(await page.isVisible('.sync-success')).toBeTruthy();
});

性能测试策略

GitButler还包含性能测试套件:

// tests/perf.spec.ts
import { performance } from 'perf_hooks';

describe('Performance Tests', () => {
  test('branch switching performance', async () => {
    const startTime = performance.now();
    
    // 执行分支切换操作
    for (let i = 0; i < 100; i++) {
      await switchToBranch(`test-branch-${i}`);
    }
    
    const endTime = performance.now();
    const duration = endTime - startTime;
    
    // 性能断言:100次切换应在5秒内完成
    expect(duration).toBeLessThan(5000);
  });
});

测试覆盖率监控

项目使用工具监控测试覆盖率:

指标目标覆盖率当前状态
Rust代码覆盖率85%+监控中
TypeScript覆盖率80%+监控中
E2E测试场景覆盖率70%+持续改进
