Forward 方法单元测试
|
||
|
||
本测试文件为 RTP 插件的 Forward 方法提供了全面的单元测试。
|
||
|
||
测试覆盖范围：
|
||
|
||
1. 方法签名验证
|
||
- TestForwardCompilation: 验证 Forward 方法编译正确
|
||
- TestForwardMethodSignature: 验证方法签名和基本结构
|
||
|
||
2. 实际调用测试
|
||
- TestForwardUDPToUDP: 测试 UDP 到 UDP 的转发
|
||
- TestForwardTCPToUDP: 测试 TCP 到 UDP 的转发
|
||
- TestForwardUDPToTCP: 测试 UDP 到 TCP 的转发
|
||
- TestForwardTCPToTCP: 测试 TCP 到 TCP 的转发
|
||
- TestForwardRelayMode: 测试 relay 模式（SSRC=0）
|
||
- TestForwardWithSSRCFiltering: 测试 SSRC 过滤功能
|
||
- TestForwardWithLargePayload: 测试大 payload 的分片处理
|
||
|
||
3. 错误处理测试
|
||
- TestForwardInvalidRequest: 测试无效请求的处理
|
||
- TestForwardConnectionTimeout: 测试连接超时处理
|
||
|
||
测试目标：
|
||
- 确保 Forward 方法的方法签名正确
|
||
- 验证不同传输模式组合的功能
|
||
- 测试 payload 数据的一致性
|
||
- 验证 SSRC 过滤和修改功能
|
||
- 测试大 payload 的分片处理
|
||
- 确保错误处理的健壮性
