michael@0 | 5 | # This file is meant to be included into an target to create a unittest that |
michael@0 | 6 | # invokes a set of no-compile tests. A no-compile test is a test that asserts |
michael@0 | 7 | # a particular construct will not compile. |
michael@0 | 8 | # |
michael@0 | 9 | # Also see: |
michael@0 | 10 | # http://dev.chromium.org/developers/testing/no-compile-tests |
michael@0 | 11 | # |
michael@0 | 12 | # To use this, create a gyp target with the following form: |
michael@0 | 13 | # { |
michael@0 | 14 | # 'target_name': 'my_module_nc_unittests', |
michael@0 | 15 | # 'type': 'executable', |
michael@0 | 16 | # 'sources': [ |
michael@0 | 17 | # 'nc_testset_1.nc', |
michael@0 | 18 | # 'nc_testset_2.nc', |
michael@0 | 19 | # ], |
michael@0 | 20 | # 'includes': ['path/to/this/gypi/file'], |
michael@0 | 21 | # } |
michael@0 | 22 | # |
michael@0 | 23 | # The .nc files are C++ files that contain code we wish to assert will not |
michael@0 | 24 | # compile. Each individual test case in the file should be put in its own |
michael@0 | 25 | # #ifdef section. The expected output should be appended with a C++-style |
michael@0 | 26 | # comment that has a python list of regular expressions. This will likely |
michael@0 | 27 | # be greater than 80-characters. Giving a solid expected output test is |
michael@0 | 28 | # important so that random compile failures do not cause the test to pass. |
michael@0 | 29 | # |
michael@0 | 30 | # Example .nc file: |
michael@0 | 31 | # |
michael@0 | 32 | # #if defined(TEST_NEEDS_SEMICOLON) // [r"expected ',' or ';' at end of input"] |
michael@0 | 33 | # |
michael@0 | 34 | # int a = 1 |
michael@0 | 35 | # |
michael@0 | 36 | # #elif defined(TEST_NEEDS_CAST) // [r"invalid conversion from 'void*' to 'char*'"] |
michael@0 | 37 | # |
michael@0 | 38 | # void* a = NULL; |
michael@0 | 39 | # char* b = a; |
michael@0 | 40 | # |
michael@0 | 41 | # #endif |
michael@0 | 42 | # |
michael@0 | 43 | # If we needed disable TEST_NEEDS_SEMICOLON, then change the define to: |
michael@0 | 44 | # |
michael@0 | 45 | # DISABLE_TEST_NEEDS_SEMICOLON |
michael@0 | 46 | # TEST_NEEDS_CAST |
michael@0 | 47 | # |
michael@0 | 48 | # The lines above are parsed by a regexp so avoid getting creative with the |
michael@0 | 49 | # formatting or ifdef logic; it will likely just not work. |
michael@0 | 50 | # |
michael@0 | 51 | # Implementation notes: |
michael@0 | 52 | # The .nc files are actually processed by a python script which executes the |
michael@0 | 53 | # compiler and generates a .cc file that is empty on success, or will have a |
michael@0 | 54 | # series of #error lines on failure, and a set of trivially passing gunit |
michael@0 | 55 | # TEST() functions on success. This allows us to fail at the compile step when |
michael@0 | 56 | # something goes wrong, and know during the unittest run that the test was at |
michael@0 | 57 | # least processed when things go right. |
