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 as a necessary step in order to assess its maturity level. * *

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 /** * @page test_msg_001 Messages Server loop * *

Description

* The test expect to receive the messages in the correct sequence and to * not find a fifth message waiting. */ static char *msg1_gettest(void) { return "Messages, loop"; } static msg_t thread(void *p) { chMsgSend(p, 'A'); chMsgSend(p, 'B'); chMsgSend(p, 'C'); chMsgSend(p, 'D'); return 0; } static void msg1_execute(void) { msg_t msg; /* * Testing the whole messages loop. */ threads[0] = chThdCreateStatic(wa[0], WA_SIZE, chThdGetPriority() + 1, thread, chThdSelf()); chMsgRelease(msg = chMsgWait()); test_emit_token(msg); chMsgRelease(msg = chMsgWait()); test_emit_token(msg); chMsgRelease(msg = chMsgWait()); test_emit_token(msg); test_assert_sequence(1, "ABC"); /* * Testing message fetch using chMsgGet(). * Note, the following is valid because the sender has higher priority than * the receiver. */ msg = chMsgGet(); test_assert(1, msg != 0, "no message"); chMsgRelease(0); test_assert(2, msg == 'D', "wrong message"); /* * Must not have pending messages. */ msg = chMsgGet(); test_assert(3, msg == 0, "unknown message"); } const struct testcase testmsg1 = { msg1_gettest, NULL, NULL, msg1_execute }; #endif /* CH_USE_MESSAGES */ /* * Test sequence for messages pattern. */ const struct testcase * const patternmsg[] = { #if CH_USE_MESSAGES &testmsg1, #endif NULL };
