I certainly see your point. <br></div><div><br></div><div>> In either case, if you wanted to change the test input, you'd need to rerun CMake again</div><div>This is unfortunate, I would have hoped I could have CMake create $(wildcard *.yaml) type of output in the make files.

I think it is only used in one test, though. Would you recommend that I do what is done in unittest/ObjectYAML/MinidumpYAMLTest.cpp which just uses a string inside the source file, or use an Inputs directory? Both are not great, as you point out about using an Inputs directory. <br></div><div><br></div><div>Also, I'm not sure that I can create an object without invoking yaml2obj itself, I can't seem to find a function to do this exposed by libObjectYAML. If I do need to invoke yaml2obj, would you happen to know how to tell CMake to build yaml2obj first, and also where would I find that executable? Thanks so much, James.</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jun 24, 2019 at 5:19 AM James Henderson <<a href="mailto:jh7370.2008@my.bristol.ac.uk">jh7370.2008@my.bristol.ac.uk</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi Alex,<br></div><div><br></div><div>Not answering your question directly, but I'd highly recommend against using CMake to bake the test outputs at the cmake step for several different reasons:</div><div><br></div><div>1) If yaml2obj changes, you'd have to rerun cmake to see whether the new version would cause the tests to fail.
