Does "vanilla" Ruby dotenv pick up any file other than .env?

I want to use environment-specific variables in my non-Rails Ruby application.

I tried different file names like .env.test.local, .env.local, .env.test

I tried using the Dotenv.load and require 'dotenv/load' approaches

This is how I wrap the task

require 'rspec'
require 'rack/test'
require 'rspec/core/rake_task'
require 'dotenv/tasks'

task test: :dotenv do
  RSpec::Core::RakeTask.new(:spec).run_task(verbose: true)
end

This is my server

require 'dotenv/load'
require 'sinatra'
require 'sinatra/reloader' if development?

set :bind, '0.0.0.0'

get ENV['API_URL'] do
  'Hello World!'
end

My .env.test file

API_URL=/api/v1

Expected behavior

The API_URL variable should be available to the code run by the :test task (using bundle exec rake test).

Observed behavior

An error caused because ENV['API_URL'] is null.

An error occurred while loading ./spec/server_spec.rb.

I came up with this workaround

require 'dotenv'
require 'sinatra'
require 'sinatra/reloader' if development?
Dotenv.load(".env.#{ENV['APP_ENV']}") # Remember to set your app environment

set :bind, '0.0.0.0'

get ENV['API_URL'] do
  'Hello World!'
end

It only works for .env.<ENVIROMENT> files. Maybe this could be wrapped in a function but I definitely would like this to be handled by the gem as in Rails applications, it makes more sense to me.
