Protractor failed to start test with firefox

Question

I can not start the test with protractor on firefox version 56.0.1. my protractor version is 5.1.2

exports.config = {
    allScriptsTimeout: 11000,
    specs: [
        './e2e/**/*.e2e-spec.ts'
    ],
    capabilities: {
        'browserName': 'firefox'
    },

    directConnect: true,
    baseUrl: 'http://localhost:4444/',
    framework: 'jasmine',
    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000,
        print: function() {}
    },
};

this is the error:

do you have any idea how to solve this problem . (it it work normally with chrome but shows empty page with firefox)

Answer 1

With geckodriver, you'll need to add marionette to the capabilities:

capabilities: {
    'browserName': 'firefox',
    'marionnette': true
},

UPDATE: There is a open issue #4253 introduced in Protractor 5.1.1 . The workaround is to manually replace directConnect with seleniumAddress and manually start webdriver-manager as specified in the bug:

The solution is to use selenium standalone when testing with Firefox. The latest version of the selenium standalone server is compatible with Protractor's selenium JS bindings and with geckodriver. You can update and launch the standalone server with

webdriver-manager update 
webdriver-manager start 

and set seleniumAddress: http://localhost:4444

Answer 2

If you are opting for directconnect then you dont need to specify the base url and don't need to start explicitly the webdriver server.

exports.config = {
    allScriptsTimeout: 11000,
    specs: [
        './e2e/**/*.e2e-spec.ts'
    ],
    capabilities: {
        'browserName': 'firefox'
    },

    directConnect: true,
    framework: 'jasmine',
    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000,
        print: function() {}
    },
};

In my case, running it with 'sudo' did not work. I had to change file permissions and then ran it without sudo.
