PhantomJS is going away

[garris]

Everybody ok with that?

What should the depreciation plan be?

You can probably start by throwing a deprecation warning somewhere e.g. what Selenium did.

I have no clue how long to keep it around but deprecated 😞 You could just ride Selenium's coat tails? When they finally kill it so does Backstop?

This may be a noob question, but does this mean backstop's casperjs support will also go away?

Yep, though [Pupeeteer](https://github.com/GoogleChrome/puppeteer/) could replace the functionality of casperjs.

Backstop is not picking up puppeteer engine and defaults to Casper engine

I'm trying to move my snapshot tests from Chromy to Puppeteer. But after updating the backstop.json, it has started defaulting to Casper.
Can anyone help me find out if I have configured it correctly.

Following is my backstop.json :
{ 'viewports': [ { 'name': 'group_1', 'width': 320, 'height': 568 }, { 'name': 'group_2', 'width': 599, 'height': 899 }, { 'name': 'group_3', 'width': 768, 'height': 1024 }, { 'name': 'group_4', 'width': 1440, 'height': 2568 } ], 'scenarios': scenarios.map(require), 'paths': { 'bitmaps_reference': 'bitmaps_reference', 'bitmaps_test': 'bitmaps_test', 'engine_scripts': 'scripts', 'html_report': 'html_report', 'ci_report': 'ci_report' }, 'openReport': false, 'casperFlags': [], 'engine': 'puppeteer', 'engineOptions': { 'ignoreHTTPSErrors': true, 'slowMo': 500, 'args': [ '--no-sandbox', '--disable-setuid-sandbox', '--disable-gpu', '--force-device-scale-factor=1', '--disable-infobars=true', '--hide-scrollbars' ], 'waitTimeout': 120000 }, 'report': process.env.UI_TEST_ENV === 'ci' ? ['ci'] : ['browser'], 'debug': true, 'asyncCaptureLimit': 2, 'asyncCompareLimit': 2 }

Console logs :

Thanks.

Please follow the instructions below to do a clean install of a reference implementation that runs puppeteer. Modify the config from there to suit your needs.

Hi!

As phantom/slimer/casper were removed (See 9805cad ), Firefox is no longer supported, right?
Then

BackstopJS/docker/Dockerfile

Line 23 in fd1af22

RUN apt-get install -y firefox-esr

can (and should) be removed as well, to keep the docker image slim and the build faster.

Also a reminder, that Foxr (See #835) is going strong and it could re-add Firefox support. :)
