Adding extra path / gempath during tests?

[Jason Pleau <jason@jpleau.ca>]

Hi.

I am trying to finalize the update of ruby-neovim to its latest upstream
release.

I have the following files in the source repo [1]:

# executable called by neovim when trying to run ruby code
./bin/neovim-ruby-host

# the actual ruby code for the gem
./lib/*


Now my problem: this gem has tests calling /usr/bin/nvim and requiring
the neovim-ruby-host to be in $PATH, and the gem to be installed (the
neovim-ruby-host has a require 'neovim/host' line).

Those tests work if I either install the gem with "gem install neovim"
or if I build the package with tests disabled. I would like the tests to
work whether or not the gem is installed.

How can I work around this? Adding ./bin/ to $PATH and somehow making
./lib/ available to ruby so 'require' works would be my first thought,
but I don't know how to that in debian/rules.
