Mmm sorry I think I didn't get the whole picture here. Is it something like this?

At the moment test's source code can be pulled from a git repository just before building.

We are also planning to add functionality for installing a test (parser+fuego_test.sh+spec) from a git repository:
ftc install-test https://github.com/xx/mytest.git

Yeah, I think this is a completely different approach. We want to focus on
an easy-to-use tool that anyone can use for running tests. Having only two
jobs would complicate the visualization graphics, download links, comparisons
between test results, etc..

I'm sorry to hear that Fuego didn't fit your use case. I really appreciate all of your
comments and feedback. I hope you have a good vacation :)
