opam switch create . ocaml-base-compiler.4.08.1
opam install --deps-only -y . --with-test

Build

dune build

Run Tests

First create ethereal.email account and store account details

curl -d '{ "requestor": "letters", "version": "0.1.0" }' "https://api.nodemailer.com/user" -X POST -H "Content-Type: application/json" > ethereal_account.json

Currently using ethereal.email service requires non-released version of colombe and
you need to checkout the project, commit edf757c58fce58c170c63e8a92d3bc81fe4d32ff contains the needed fix. Then the version with the fix needs to be pinned in the build env:

cd /path/to/colombe
opam switch /path/to/letters
# Follow instructions to evaluate the environment
git switch --detach edf757c58fce58c170c63e8a92d3bc81fe4d32ff
opam pin .
# Finally, return back to letters project
cd /path/to/letters

Then execute the tests

dune test

And finally review that the email is correctly generated in the service:

• login to https://ethereal.email/login using credentials from the ethereal_account.json

• check the content of messages: https://ethereal.email/messages
