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