I've recently started using Backstop JS for visual regression testing. You can add the following settings to your Lando configuration, .lando.yml, to include Backstop JS.

services:
   node:
     type: node:10
     globals:
       backstopjs: "latest"
     command: npm start
     run_as_root:
       - apt-get -y update && apt-get -y install software-properties-common
       - wget https://dl-ssl.google.com/linux/linux_signing_key.pub && apt-key add linux_signing_key.pub
       - add-apt-repository "deb http://dl.google.com/linux/chrome/deb/ stable main"
       - apt-get -y update && apt-get -y install google-chrome-stable
 tooling:
   backstop:
     service: node

You will need to use the .internal URL from Lando to access the local website. For example:

  "scenarios": [
    {
      "label": "Homepage",
      "url": "http://appserver_nginx.your-site-name.internal"
    }

The backstop commands will be run through Lando tooling:

lando backstop reference
lando backstop test
