Ceedling TEST_CASE does not work with blinky

[professor-frink]

Good morning,

Given the following setup:

• Windows 10 PC
• mingw installed to C:\mingw\bin
• gcc version: gcc (MinGW.org GCC-6.3.0-1) 6.3.0
• Ruby version: ruby 2.4.1p111 (2017-03-22 revision 58053) [x64-mingw32]
• Ceedling:: 0.31.1
• CMock:: 2.5.4
• Unity:: 2.5.4
• CException:: 1.3.3

Problem: I get undefined/differeng TEST_CASE values in the failed test assertion versus the test I wrote

Steps to reproduce:

1. Modify project.yml to point to C:\mingw\bin
2. I modified test_main.c to be as follows adding a new parametric test, "test_actual_value": #include "unity.h" #include "main.h" #include "stub_io.h" #include "mock_Configure.h" #include "mock_BlinkTask.h" #define TEST_CASE(...) void setUp(void) {} // every test file requires this function; // setUp() is called by the generated runner before each test case function void tearDown(void) {} // every test file requires this function; // tearDown() is called by the generated runner before each test case function

// test_main.c as is... TEST_CASE(5) void test_actual_value(int actual) { int expected = 1; TEST_ASSERT_EQUAL(expected,actual); }

After issuing ceedling test:main I get a failure, but not with the test case I injected

Test 'test_main.c'

FAILED TEST SUMMARY

[test_main.c] Test: test_actual_value At line (67): "Expected 1 Was 4272392"

After commenting out :use_test_preprocessor:, the actual value used in the test changes from 427392 to the expected 5.

Question

1. Why is this the case?
2. Am I doing something wrong in implementing TEST_CASE? I can't find any documentation on TEST_CASE, or use_test_preprocessor, or TEST_RANGE in the Ceedling documentation. Am I looking in the wrong place?

Thanks!
