test_scenario 实体

所属模块：数据模型概览

---

1. 表定义

表名：test_scenario

描述：存储测试场景，通过外键关联各维度表，test_purpose 直接存储

---

2. 字段定义

列名	类型	约束	说明
id	UUID	PK, NOT NULL	主键，自动生成
tx_panel_id	UUID	FK, NOT NULL	关联TX面板维度
tx_hardware_id	UUID	FK, NOT NULL	关联TX硬件版本维度
tx_software_id	UUID	FK, NOT NULL	关联TX软件版本维度
rx_type_id	UUID	FK, NOT NULL	关联RX类型维度
test_purpose	VARCHAR(200)	NULL	测试目的（直接存储）
test_date	DATE	NOT NULL	测试日期
test_sequence	INT	NOT NULL, DEFAULT 1	测试次数序号
qfod_count	INT	NOT NULL, DEFAULT 0	包含的 Qfod 记录数
ploss_count	INT	NOT NULL, DEFAULT 0	包含的 Ploss 记录数
is_deleted	BOOLEAN	NOT NULL, DEFAULT FALSE	软删除标记
created_at	TIMESTAMP	NOT NULL, DEFAULT NOW()	入库时间

---

3. 外键

外键	引用表	说明
tx_panel_id	tx_panel.id	关联TX面板维度（必需）
tx_hardware_id	tx_hardware.id	关联TX硬件版本维度（必需）
tx_software_id	tx_software.id	关联TX软件版本维度（必需）
rx_type_id	rx_type.id	关联RX类型维度（必需）

---

4. 索引

索引名	字段	用途
idx_scenario_tx_panel	tx_panel_id	按面板类型筛选
idx_scenario_tx_hardware	tx_hardware_id	按硬件版本筛选
idx_scenario_tx_software	tx_software_id	按软件版本筛选
idx_scenario_rx_type	rx_type_id	按RX类型筛选
idx_scenario_test_date	test_date	按测试日期查询

---

5. 唯一约束

约束名	字段组合	说明
uq_scenario	(tx_panel_id, tx_hardware_id, tx_software_id, rx_type_id, test_purpose, test_date, test_sequence)	相同属性组合不重复创建

关于 test_purpose 的 NULL 处理：由于 test_purpose 是可空字段，含 NULL 的唯一约束在不同数据库中行为不同：

• PostgreSQL：默认允许多个 NULL（被视为不同值），可通过 NULLS NOT DISTINCT 约束行为
• SQL Server：只允许一个 NULL
• SQLite/MySQL：允多个 NULL

若需严格幂等（无论 test_purpose 是否为 NULL 都不重复），建议使用 filtered index 或将空值转为默认字符串（如 (empty)）。

6. EF Core 模型

7. 场景创建流程

从文件名解析

// Services/ScenarioService.cs
public async Task<TestScenario> GetOrCreateScenarioAsync(ScenarioInfo info)
{
    // 1. 获取或创建各维度（通过 DimensionService）
    var txPanel = await _dimensionService.GetOrCreateTxPanelAsync(info.TxPanel);
    var txHardware = await _dimensionService.GetOrCreateTxHardwareAsync(info.TxHardware);
    var txSoftware = await _dimensionService.GetOrCreateTxSoftwareAsync(info.TxSoftware);
    var rxType = await _dimensionService.GetOrCreateRxTypeAsync(info.RxType);
    
    // 2. 检查场景是否已存在（利用唯一约束）
    var existing = await _context.TestScenarios
        .FirstOrDefaultAsync(s => 
            s.TxPanelId == txPanel.Id &&
            s.TxHardwareId == txHardware.Id &&
            s.TxSoftwareId == txSoftware.Id &&
            s.RxTypeId == rxType.Id &&
            s.TestPurpose == info.TestPurpose &&
            s.TestDate == info.TestDate &&
            s.TestSequence == info.TestSequence);
    
    if (existing != null) return existing;
    
    // 3. 创建新场景
    var scenario = new TestScenario
    {
        TxPanelId = txPanel.Id,
        TxHardwareId = txHardware.Id,
        TxSoftwareId = txSoftware.Id,
        RxTypeId = rxType.Id,
        TestPurpose = info.TestPurpose,
        TestDate = info.TestDate,
        TestSequence = info.TestSequence
    };
    
    _context.TestScenarios.Add(scenario);
    await _context.SaveChangesAsync();
    
    return scenario;
}

手动创建

public async Task<TestScenario> CreateAsync(CreateScenarioRequest request)
{
    // 1. 验证维度是否存在
    var txPanel = await context.TxPanels.FindAsync(request.TxPanelId)
        ?? throw new NotFoundException("TX面板不存在");
    var txHardware = await context.TxHardwares.FindAsync(request.TxHardwareId)
        ?? throw new NotFoundException("TX硬件版本不存在");
    // ... 其他维度验证
    
    // 2. 创建场景
    var scenario = new TestScenario
    {
        TxPanelId = request.TxPanelId,
        TxHardwareId = request.TxHardwareId,
        TxSoftwareId = request.TxSoftwareId,
        RxTypeId = request.RxTypeId,
        TestPurpose = request.TestPurpose,
        TestDate = request.TestDate,
        TestSequence = request.TestSequence
    };
    
    context.TestScenarios.Add(scenario);
    await context.SaveChangesAsync();
    
    return scenario;
}
