Inferno Core

Inferno Core is an open source tool for testing data exchanges enabled by the Fast Healthcare Interoperability Resources (FHIR) standard.

If you are interested in developing tests using Inferno Core, use the Inferno Template Repository.


Contributing to Inferno Core

Developers interested in contributing to the Inferno Core gem must have Ruby 2.7+ and Node.js and NPM installed.

Using Inferno Core to author tests

If you are interested in developing tests using Inferno Core, use the Inferno Template Repository. These instructions are for developers working on Inferno Core itself.

# Install dependencies
npm install
bundle install

# Set up database
bundle exec bin/inferno migrate

# Start Inferno Core server and UI
npm run dev

Inferno Core can then be accessed by navigating to localhost:4567/inferno

To only run the server (JSON API with no UI): bundle exec puma

Running tests via JSON API

With the server running, first retrieve a list of available test suites: GET http://localhost:4567/inferno/api/test_suites See the details of a test suite: GET http://localhost:4567/inferno/api/test_suites/TEST_SUITE_ID Then create a test session for the suite you want to use: POST http://localhost:4567/inferno/api/test_sessions?test_suite_id=TEST_SUITE_ID Tests within a suite are organized in groups. Create a test run to run an entire suite, a group, or an individual test. Only one of test_suite_id, test_group_id, or test_id should be provided. POST http://localhost:4567/inferno/api/test_runs { "test_session_id": "TEST_SESSION_ID", "test_suite_id": "TEST_SUITE_ID", "test_group_id": "TEST_GROUP_ID", "test_id": "TEST_ID", "inputs": [ { "name": "input1", "value": "input1 value" }, { "name": "input2", "value": "input2 value" } ] } Then you can view the results of the test run: GET http://localhost:4567/inferno/api/test_runs/TEST_RUN_ID/results or GET http://localhost:4567/inferno/api/test_sessions/TEST_SESSION_ID/results


To get to an interactive console, run bundle exec bin/inferno console

Customizable Banner

Inferno Core allows you to add your own customizable banner. It loads the banner from the config/banner.html.erb file and renders it above the application. The size and appearance of the banner can be controlled by using the inline style attribute.


Inferno documentation source code is located in the docs/ directory. This documentation is rendered using Jekyll, which creates a site that can be built and served with:

cd docs/
bundle install
bundle exec jekyll serve

By default the site will be served at http://localhost:4000/inferno-core/
