|
|
|
+ * @brief Comprehensive test suite for RT-Thread SAL (Socket Abstraction Layer) socket operations
|
|
|
+ *
|
|
|
+ * @note This test suite validates:
|
|
|
+ * - 1.basic socket creation with valid and invalid parameters
|
|
|
+ * - 2.socket binding functionality with proper address configuration
|
|
|
+ * - 3.listen operation with various backlog configurations
|
|
|
+ * - 4.TCP connection establishment and error handling
|
|
|
+ * - 5.accept operation with timeout and error conditions
|
|
|
+ * - 6.TCP data transmission (send/receive) with echo verification
|
|
|
+ * - 7.UDP communication including sendto/recvfrom operations
|
|
|
+ * - 8.proper socket closure and cleanup procedures
|
|
|
+ * - 9.socket address information retrieval (getsockname/getpeername)
|
|
|
+ * - 10.network device status checking and fallback mechanisms
|
|
|
+ * - 11.thread-safe socket operations using RT-Thread synchronization
|
|
|
+ * - 12.socket timeout configuration and non-blocking mode handling
|
|
|
+ * - 13.error handling for invalid parameters and network failures
|
|
|
+ * - 14.port management to avoid conflicts during concurrent testing
