Test fails

[GuillaumeDesforges]

While packaging haskell-language-server on nixpkgs: NixOS/nixpkgs#91279

I encountered floskell error on check phase:

Running 1 test suites...
Test suite floskell-test: RUNNING...
floskell-test: styles/base.md: openBinaryFile: does not exist (No such file or directory)
Test suite floskell-test: FAIL

It seems in the nix environment the test is run with a different working directory compared to non-nix cabal test/stack test runs. I'm looking into using the full source path to load the test files.
