deepin pr auto review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:
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());
}
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。 |
