`I have a Melange project with the following directory structure:

├── src
│   ├── dune
│   ├── App.re
├── __tests__
│   ├── dune
│   ├── App_test.re

The dune files in both the src and __tests__ folders use a melange.emit stanza to compile the directories into javascript during the build. I want my App_test.re file to use the App module defined in App.re, but in order to do so, I need to create a library stanza in the src/dune file that includes the App module, and then declare that library in my melange.emit stanza in the __tests__/dune file. The problem with this is that my melange.emit stanza in my src/dune already includes App as a module, so I’m unable to also declare a library in src/dune that contains the App module. How can I get my App_test.re file to open my App module without throwing the error “Unbound module App”?

I’ve tried to set this up following the instructions on the Github for melange-jest (the testing framework I’m using) but there’s not any documentation specifying how to fix this issue.
