+/**
+ * @brief Test flushing a pipe
+ *
+ * @ingroup kernel_pipe_tests
+ *
+ * @details
+ * Test Objective:
+ * - Check if the kernel flushes a pipe properly at runtime.
+ *
+ * Testing techniques:
+ * - function and block box testing,Interface testing,
+ * Dynamic analysis and testing.
+ *
+ * Prerequisite Conditions:
+ * - CONFIG_TEST_USERSPACE.
+ *
+ * Input Specifications:
+ * - N/A
+ *
+ * Test Procedure:
+ * -# Define and initialize a pipe at run time
+ * -# Use this pipe to transfer data.
+ * -# Have a thread fill and block on writing to the pipe
+ * -# Flush the pipe and check that the pipe is completely empty
+ * -# Have a thread fill and block on writing to the pipe
+ * -# Flush only the pipe's buffer and check the results
+ *
+ * Expected Test Result:
+ * - Reading from the pipe after k_pipe_flush() results in no data to read.
+ * - Reading from the pipe after k_pipe_buffer_flush() results in read data,
+ *   but missing the original data that was in the buffer prior to the flush.
+ *
+ * Pass/Fail Criteria:
+ * - Successful if check points in test procedure are all passed, otherwise
+ * failure.
+ *
+ * Assumptions and Constraints:
+ * - N/A
