$ cabal --version
cabal-install version 2.0.0.0
compiled using version 2.0.1.0 of the Cabal library
I'll work on preparing a minimal example in a bit. In the meantime, you can trigger this issue with scotty-0.11.0:
$ cabal get scotty-0.11.0
Unpacking to scotty-0.11.0/
$ cd scotty-0.11.0/
$ cat > cabal.project << EOF
> packages: .
> package scotty
> library-coverage: true
> EOF
$ cabal new-test

In order, the following will be built (use -v for more details):
- scotty-0.11.0 (lib) (first run)
- scotty-0.11.0 (test:spec) (first run)

cabal: Tests failed for test:spec from scotty-0.11.0.
This error doesn't happen for another project, wai-middleware-static-0.8.1. Unlike scotty, wai-middleware-static has no other-modules, so I suspect that is the culprit here.
