ddev-backstopjs's Introduction

tests project is maintained

ddev-backstopjs

This is a ddev-addon for backstop.js, a visual regression testing tool. Backstop is executed in a docker container based on the official backstopjs docker image.

This addon just provides the basics to run backstopjs. No backstopjs config is included. See below how to generate a config and for links to a more advanced example config.

Getting started

Install this addon with

ddev get mmunz/ddev-backstopjs

After that you need to restart the ddev project:

ddev restart

Note: If you haven't downloaded the backstopjs base image before, then it will be downloaded when ddev is restarted. The backstopjs/backstopjs is about 2.6GB, so this may take some time.

Using backstopjs

Configuration

By default, the backstop tests are expected in $DDEV_APPDIR/tests/backstop.

Provide your own backstop.js or backstop.json configs there.

Hint: have a look at my example backstopjs-config

Alternatively you can create a simple backstop.json config with:

ddev backstop init

Run tests

After the config was created it is time to run the tests:

Create reference screenshots:

ddev backstop reference

Create test images and compare to reference screenshots:

ddev backstop test

If your config file is not 'backstop.json' you need to use the --config argument, e.g. --config=backstop.js

View test results

The backstop commands 'backstop remote' and 'backstop openReport' do not work in this setup.

But there is a host command that will open the latest test report in your default browser:

ddev backstop-results

Alternatively open the generated HTML-Report with your browser, e.g.:

open tests/backstop/backstop_data/_mytestproject_/html_report/index.html

Changes to the original docker image

The backstopjs docker image is extended with some functions using a custom docker build, see Dockerfile and uses a custom entrypoint.

In the Dockerfile the following is added/changed:

  • add the custom entrypoint.sh to the image
  • delete the default 'node' user with uid 1000 and add current ddev user
  • install the minimist npm package globally. This is not needed by default but very handy to parse command line args for more complex custom backstopjs configs.

The entrypoint is responsible for:

  • add /etc/hosts entries for all hosts configured in the ddev web container automatically
  • add sleep command to keep the container running

Advanced

How to add additional hostnames?

If you want to test hosts not configured in the web container, you need to use external_links in the service containers. For that add a file docker-compose.external_links.yaml to your project which should look like this:

services:
  backstop:
    external_links:
      - "ddev-router:myproject.ddev.site"
      - "ddev-router:myproject2.ddev.site"

See: ddev FAQ: Can different projects communicate with each other?

Change backstop tests directory

Per default the backstop directory containing backstop config etc. is expected in your project directory (besides the .ddev folder) in the directory tests/backstop.

If you want to change that edit the file docker-compose.backstop.yaml and change the line in volumes to the path you want to use, move the files to the new directory and restart ddev.

Make sure to remove the #ddev-generated line from the file to prevent ddev from making changes to it.

ddev-backstopjs's Issues

First run after install is slow without any feedback to the user

Right after ddev get mmunz/ddev-backstopjs and ddev restart the restart takes a long time. I suppose it downloads backstop. There is nothing displayed to the end user however. Is the default ddev output when downloading images supresed somehow?

It's not a big deal, but definitely a good thing to have, especially for people on slow connections

Could not use it

I'm trying to use this addon but I get following error:

I'm not sure why I get

Any suggestion on how to solve this?

Can't update addon if `## dev-generated` is removed from gitignore

The de-facto way of updating ddev addons is by running ddev get again:

ddev get mmunz/ddev-backstopjs

This fails if .gitignore is self-managed:

$ ddev get mmunz/ddev-backstopjs --verbose

I have removed ## ddev-generated line from the .gitignore file, as I do not want to store the reference files.

This is a minor issue, but might be good to find a way around it, especially if there are plans to add this to the official addons in the future.

Thanks
