Configure Polymer web-component-tester to use a Selenium Grid server - unit-testing

Question

I need to configure the Polymer web-component-tester to use a Selenium Grid running at http://jenkins.myapp.corp.web:4444/wd/hub so I can run my tests on Jenkins. What is the Grunt config for this? I guessing something like this:
'wct-test': {
local: {
options: {
activeBrowsers: [{
browserName: 'chrome',
url: 'http://jenkins.myapp.corp.web:4444/wd/hub'
}]
}
}
}

Answer 1

It turns out there was a bug with web-component-tester that has been fixed in the latest release. We ended up getting it working with our grid using this config:
var os = require('os');
...
'wct-test': {
local: {
options: {
remote: false,
activeBrowsers: [{
browserName: "chrome",
url: "http://jenkins.myapp.corp.web:4444/wd/hub"
}],
webserver: {
hostname: os.hostname()
}
}
}
}

It seems that you can modify your wct.conf.js and set your grid configuration:
module.exports = {
// See https://github.com/Polymer/web-component-tester/blob/master/runner/config.js#L47-54
activeBrowsers: [
{
// Accepts anything wd does: https://github.com/admc/wd#browser-initialization
url: 'http://user:apiKey#your.selenium.server/wd/hub',
// ... any other capabilities you like:
browserName: 'theBrowser',
}
],
plugins: {
local: false,
sauce: false,
}
};

The correct configuration for wct.conf.json should be as follows. You should change url of the sample to your selenium grid url.
{
"....":"....",
"activeBrowsers": [{
"browserName": "chrome",
"url": "http://selenium-hub-selenium.apps.com.tr/wd/hub"
}],
"plugins": {
"local": {
"disabled": true
},
"sauce":{
"disabled": true
}
}
}
