# option 1: if global webpack
webpack

# option 2: if local webpack

4) Start web server

PORT=4000 FN_API_URL=http://localhost:8080 npm start

• PORT - port to run UI on. Optional, 4000 by default
• FN_API_URL - Functions API URL. Required

5) View in browser

http://localhost:4000/

Configuring log levels

UI uses console-logging for server-side logging. This supports log levels of debug, verbose, info, warn and error. By default the log level is info (this is configured in config/default.json). To set a log level of debug, use

NODE_CONFIG='{"logLevel":"debug"}' PORT=4000 FN_API_URL=http://localhost:8080 npm start

Automated Testing

Integration tests

The Fn UI has some basic Selenium integration tests that can be used to automatically test the UI's core functionality. These tests use the mocha testing framework as the driver.

To run the tests:

1) Install the Chrome Driver

Download the ChromeDriver from Google and put it in a place which is in your path e.g. /usr/local/bin/chromedriver.

2) Install the Node dev dependencies

Ensure you have the Node dev dependencies installed with:

npm install [--only dev]

3) Run the Fn interface

See the instructions above for how to start the Node webserver.

4) Configure your tests

Edit test_integration/etc/config.yaml accordingly e.g. point fn_url to your Fn UI if you're not running it at its default location.

5) Run the tests

npm run test-integration
