Development Setup

This guide assumes you have the commands docker, go (>= 1.15), node, yarn, and make installed/available.

Database (PostgreSQL)

GoAlert is built and tested against Postgres 11. Version 9.6 should still work as of this writing, but is not recommended as future versions may begin using newer features.

The easiest way to setup Postgres for development is to run make postgres. This will start a docker container with the correct configuration for the dev environment.

Manual Configuration

If you already have Postgres running locally you can create the goalert role.

CREATE ROLE goalert WITH LOGIN SUPERUSER;

Currently the dev user must be a superuser to enable pgcrypto with CREATE EXTENSION.

Toolchain Requirements

  • For the first start, run make regendb to migrate and add test data into the DB. This includes adding an admin user admin/admin123.
  • To start GoAlert in development mode run make start.
  • To build the GoAlert binary run make bin/goalert BUNDLE=1.

Automated Browser Tests

To run automated browser tests, you can start Cypress in one of the following modes:

  • make cy-wide Widescreen format, in dev mode.
  • make cy-mobile Mobile format, in dev mode.
  • make cy-wide-prod Widescreen format, production build.
  • make cy-mobile-prod Mobile format, production build.

The Cypress UI should start automatically.

More information about browser tests can be found here.

Running Smoketests

A suite of functional/behavioral tests are maintained for the backend code. These test various APIs and behaviors of the GoAlert server component.

Run the full suite with make smoketest.

More information about smoketests can be found here.

Running Unit Tests

All unit tests can be run with make test.

UI Unit tests are found under the directory of the file being tested, with the same file name, appended with .test.js. They can be run independently of the Go unit tests with make jest. Watch mode can be enabled with make jest JEST_ARGS=--watch.
