我已经仔细审查了这些测试代码的diff。以下是我的分析和建议:

  1. 代码结构和组织:
  • 整体结构良好,测试用例按功能模块组织
  • 使用了Google Test框架,符合项目规范
  • 测试类的SetUp/TearDown方法使用得当
  1. 测试覆盖度改进:
  • 新增了大量测试用例,提高了代码覆盖率
  • 添加了边界条件测试,如空列表、无效URL等
  • 增加了错误场景的测试
  1. 具体建议:

a) 测试环境管理:

void SetUp() override {
    stub.clear();
    // 建议添加环境变量隔离
    qputenv("DFM_TRASH_TEST_MODE", "1");
    testDir = QDir::temp().absoluteFilePath("trash_test_" + QString::number(QCoreApplication::applicationPid()));
    QDir().mkpath(testDir);
}

b) 资源清理:

void TearDown() override {
    stub.clear();
    // 确保完全清理测试目录
    QDir(testDir).removeRecursively();
    // 清理环境变量
    qunsetenv("DFM_TRASH_TEST_MODE");
}

c) Mock对象管理:

// 建议使用智能指针管理mock对象
std::unique_ptr<MockObject> mockObj = std::make_unique<MockObject>();
stub.set_lamda(&SomeClass::method, [mockObj.get()]() {
    return mockObj->mockMethod();
});

d) 测试数据隔离:

// 为每个测试用例创建独立的测试数据
void createTestFiles() {
    // 使用随机数确保文件名唯一
    QString randomSuffix = QString::number(QDateTime::currentMSecsSinceEpoch());
    QFile file(testDir + "/test_" + randomSuffix + ".txt");
    // ...
}

e) 异步操作测试:

// 对于异步操作,建议使用QSignalSpy
QSignalSpy spy(object, SIGNAL(operationFinished(bool)));
// 执行异步操作
object->startAsyncOperation();
// 等待信号,设置合理的超时时间
EXPECT_TRUE(spy.wait(5000));

f) 错误处理测试:

// 添加更详细的错误场景测试
TEST_F(TestTrashHelper, HandleInvalidUrl) {
    QUrl invalidUrl("invalid://test");
    EXPECT_THROW({
        TrashHelper::processUrl(invalidUrl);
    }, std::invalid_argument);
}

g) 性能测试:

// 添加性能测试用例
TEST_F(TestTrashHelper, PerformanceTest) {
    auto start = std::chrono::high_resolution_clock::now();
    // 执行操作
    TrashHelper::processLargeDataSet();
    auto end = std::chrono::high_resolution_clock::now();
    auto duration = std::chrono::duration_cast<std::chrono::milliseconds>(end - start);
    EXPECT_LT(duration.count(), 1000); // 期望在1秒内完成
}

h) 并发测试:

// 添加并发测试用例
TEST_F(TestTrashHelper, ConcurrentAccess) {
    const int threadCount = 10;
    std::vector<std::thread> threads;
    
    for(int i = 0; i < threadCount; ++i) {
        threads.emplace_back([this]() {
            TrashHelper::performOperation();
        });
    }
    
    for(auto& thread : threads) {
        thread.join();
    }
    
    // 验证结果
    EXPECT_TRUE(verifyConcurrentResults());
}
  1. 安全性考虑:
  • 添加了文件权限测试
  • 增加了路径遍历攻击的测试
  • 添加了资源泄露的检测
  1. 代码质量:
  • 使用了更现代的C++特性
  • 改进了错误处理
  • 增加了代码注释和文档
  1. 测试报告:
  • 建议添加测试覆盖率报告
  • 添加性能基准测试报告
  • 增加测试结果的可视化展示

这些改进建议将帮助提高测试代码的质量、可维护性和可靠性。建议逐步实施这些改进,并在每个阶段进行充分的测试验证。
