… test-color-parser.c file. The file libgimpcolor/test-color-parser.c was compiled but never actually called by the build. Now that we have a nice infrastructure to test libgimp API, I am moving it there with the new format. Doing this also allowed me to discover some bugs in CSS parsing, as well as discover Python binding was failing here (cf. the few previous commits). Only one test is disabled so far, the one where 4 digits are used per channel in hexadecimal notation: "#64649595eded". This format simply doesn't appear anywhere in the spec, and also the result values in the samples listing don't even fit. So far, I'm just unsure what to do with it, if we want to keep this support (of some kind of higher precision hex notation, but not specified, so is it even used by anyone?) or not. All the other tests just work in both C and Python!
