Description

* This module implements the test sequence for the @ref messages subsystem. * *

Objective

* Objective of the test module is to cover 100% of the @ref messages * subsystem code. * *

Preconditions

* The module requires the following kernel options: * - @p CH_USE_MESSAGES * . * In case some of the required options are not enabled then some or all tests * may be skipped. * *

Test Cases

* - @subpage test_msg_001 * . * @file testmsg.c * @brief Messages test source file * @file testmsg.h * @brief Messages header file */ #if CH_USE_MESSAGES || defined(__DOXYGEN__) /** * @page test_msg_001 Messages Server loop * *

Description

* A thread is spawned that sends four messages back to the tester thread.
* The test expect to receive the messages in the correct sequence and to * not find a fifth message waiting. */ static msg_t thread(void *p) { chMsgSend(p, 'A'); chMsgSend(p, 'B'); chMsgSend(p, 'C'); return 0; } static void msg1_execute(void) { Thread *tp; msg_t msg; /* * Testing the whole messages loop. */ threads[0] = chThdCreateStatic(wa[0], WA_SIZE, chThdGetPriority() + 1, thread, chThdSelf()); tp = chMsgWait(); msg = chMsgGet(tp); chMsgRelease(tp, msg); test_emit_token(msg); tp = chMsgWait(); msg = chMsgGet(tp); chMsgRelease(tp, msg); test_emit_token(msg); tp = chMsgWait(); msg = chMsgGet(tp); chMsgRelease(tp, msg); test_emit_token(msg); test_assert_sequence(1, "ABC"); } ROMCONST struct testcase testmsg1 = { "Messages, loop", NULL, NULL, msg1_execute }; #endif /* CH_USE_MESSAGES */ /** * @brief Test sequence for messages. */ ROMCONST struct testcase * ROMCONST patternmsg[] = { #if CH_USE_MESSAGES || defined(__DOXYGEN__) &testmsg1, #endif NULL }; /iCE40/yosys/plain/tests/simple/macros.v?id=82a4a0230feedd994546ad57a1f4ae79b8f80136'>plain)
