Fails to start Firefox

[StephenTurley]

Trying to run WCT against the seed-element example project and I get the following error.

I'm running Fedora 23 and Firefox 42.

Looks related to https://github.com/yeoman/generator-polymer/issues/253

Ugh, this is because java is bad at figuring out localhost.

This happened on my home machine as well, and a workaround is to make sure 'localhost' is first in /etc/hosts

broken

127.0.0.1 localhost.localdomain localhost

works

127.0.0.1 localhost localhost.localdomain.

[Remeic]

@azakus does not seem to work, in opensuse in host was already as the first entry "localhost" and did not present instead localhost.localhostdomain. I tried to add it, but the problem remains. I attach here my hosts file

127.0.0.1 localhost

special IPv6 addresses

::1 localhost ipv6-localhost ipv6-loopback

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix ff02::1 ipv6-allnodes ff02::2 ipv6-allrouters ff02::3 ipv6-allhosts

[dfreedm]

Oh, please try with WCT 4, which uses selenium 2.48.2.

[Remeic]

@azakus I need to update generator-polymer or is there a specific passage? Thank you in advance

[robdodson]

@Remeic youll want to update this line in your package.json https://github.com/PolymerElements/polymer-starter-kit/blob/master/package.json#L33

[Remeic]

@robdodson sorry for delay . Still not working , i return on fedora where the localhost and localhost.localdomain have inverted position , i set localhost as primary and after i update package.json . i start "gulp test:local" and problem see the sam

Update , if i launch "gulp test" a new firefox windows appear but after on console appear the problem

[robdodson]

@Remeic after you updated the line in package.json did you delete node_modules and re-run npm install?

[Remeic]

@robdodson no , sorry i only run "npm install -g web-component-tester" , i mistake sorry again. But now gulp test and gulp serve work , thanks for the immense patience and the help <3

[robdodson]
