The content of this blog is my personal opinion only. Although I am an employee - currently of Nvidia, in the past of other companies such as Iagination Technologies, MIPS, Intellectual Ventures, Intel, AMD, Motorola, and Gould - I reveal this only so that the reader may account for any possible bias I may have towards my employer's products. The statements I make here in no way represent my employer's position, nor am I authorized to speak on behalf of my employer. In fact, this posting may not even represent my personal opinion, since occasionally I play devil's advocate.

abspath and simple diff tests

I like tests.

Lacking a full fledged test infrastructure, simply diffing outputfiles is often sufficient.

Except for stuff like

a) using absolute paths related to where the source tree is

b) other time and position variant stuff.

I'd almost like a diff

1) that was smart enough to recognize and skip timestamps

2) that was smart enough to recognize absolurte/relative file patterns.

I have added relative/absolute file options to many tools - so often that I suspect it is not the tools fault, but really should be fixed in the test infrastructure.

I have preprocessed expected output files - but that can be fragile, if the preprocess tool breaks and, e.g., gives an empty string.
