+
+# This file is meant to be included into an target to create a unittest that
+# invokes a set of no-compile tests.  A no-compile test is a test that asserts
+# a particular construct will not compile.
+#
+# Also see:
+#   http://dev.chromium.org/developers/testing/no-compile-tests
+#
+# To use this, create a gyp target with the following form:
+#
+# import("//build/nocompile.gni")
+# nocompile_test("my_module_nc_unittests") {
+#   sources = [
+#     'nc_testset_1.nc',
+#     'nc_testset_2.nc',
+#   ]
+#
+#   # optional extra include dirs:
+#   include_dirs = [ ... ]
+# }
+#
+# The .nc files are C++ files that contain code we wish to assert will not
+# compile.  Each individual test case in the file should be put in its own
+# #ifdef section.  The expected output should be appended with a C++-style
+# comment that has a python list of regular expressions.  This will likely
+# be greater than 80-characters. Giving a solid expected output test is
+# important so that random compile failures do not cause the test to pass.
+#
+# Example .nc file:
+#
+#   #if defined(TEST_NEEDS_SEMICOLON)  // [r"expected ',' or ';' at end of input"]
+#
+#   int a = 1
+#
+#   #elif defined(TEST_NEEDS_CAST)  // [r"invalid conversion from 'void*' to 'char*'"]
+#
+#   void* a = NULL;
+#   char* b = a;
+#
+#   #endif
+#
+# If we needed disable TEST_NEEDS_SEMICOLON, then change the define to:
+#
+#   DISABLE_TEST_NEEDS_SEMICOLON
+#   TEST_NEEDS_CAST
+#
+# The lines above are parsed by a regexp so avoid getting creative with the
+# formatting or ifdef logic; it will likely just not work.
+#
+# Implementation notes:
+# The .nc files are actually processed by a python script which executes the
+# compiler and generates a .cc file that is empty on success, or will have a
+# series of #error lines on failure, and a set of trivially passing gunit
+# TEST() functions on success. This allows us to fail at the compile step when
+# something goes wrong, and know during the unittest run that the test was at
+# least processed when things go right.
