llvm dev - Jan 2019 - Is ist a good idea to use lit and other test tools for non llvm projects?

Hi,

I have a project which uses llvm, but is (at least not yet) a
contribution / not in the source tree of llvm.
Is it a good idea (e.g. instead of using boost test framework) to use
the llvm testsuite related tools in this case?

That probably depends on the project, but I've long wished LLVM's
testing tools were available outside of LLVM, packaged up separately so
they could be more widely used.  They're great tools!

lit is, in fact, packaged separately--it is available on PyPI.
FileCheck isn't; there is a similar tool on PyPI, called OutputCheck,
which I have used extensively for similar jobs (matching compiler IR) 
but
I like it much less than FileCheck.

Yes, lit can be used either from a compiled llvm package or even be
installed (its in bin/llvm-lit).
I decided to give it a try.

After of few week of applying my regression test set-up, I wanted to
state that I use lit and FileCheck (which are both found in the
llvmBuild/bin dir).
Works like a charm, and I will use it in future, even for non llvm
related projects.
