How to disable custom protocol handler for protractor? - selenium

Question

I have a Protractor test suite for an application that uses a custom protocol handler to pass messages out of an iOS web view.
When testing it with protractor, how do I prevent the custom window.location = "app://doThing"; message from breaking my tests? It shows the "Open xdg-open?" popup and doesn't continue with tests.
My protractor configuration looks like this:
exports.config = {
...,
multiCapabilities: [ {
browserName: 'chrome',
chromeOptions: {
args: [ '--lang=en', '--window-size=1024x768' ]
},
specs: 'test-*.js',
} ]
};

Answer 1

I achieved this in Chrome 60 by setting the preferences inside the chromeOptions block.
exports.config = {
...,
multiCapabilities: [ {
browserName: 'chrome',
chromeOptions: {
args: [ '--lang=en', '--window-size=1024x768' ],
// Replace "app" with your app's custom scheme.
prefs: {
protocol_handler: {
excluded_schemes: {
"app": true
}
}
},
},
specs: 'test-*.js',
} ]
};
Before Chrome 60, I enforced a profile folder for the Chrome runner. You can do that by having a folder named "/chrome-profile" in the Chrome docker container for example, and adding one file in it named "Default State" with the following content:
{
"protocol_handler": {
"excluded_schemes": {
"app": true
}
}
}
And after that, setting the Chrome user-data-dir flags as such:
exports.config = {
...,
multiCapabilities: [{
'browserName': 'chrome',
'chromeOptions' : {
args: ['--lang=en',
'--window-size=1024,768',
'--user-data-dir=/chrome-profile/']
},
specs: ['test-*.js']
}]
};
