Protractor not launching Internet Explorer or Firefox - selenium-webdriver

Question

Protractor is launching only chrome by default even if I configure the browsers to be internet explorer or firefox. I tried reinstalling the drivers again even that dint help.
My config file:
exports.config = {
multicapabilities: [{
seleniumAddress: 'http://localhost:4444/wd/hub',
'browserName' : 'chrome'
},
{
seleniumAddress: 'http://localhost:4444/wd/hub',
'browserName' : 'firefox'
}
{
seleniumAddress: 'http://localhost:4444/wd/hub',
'browserName': 'internet explorer',
'version' : '11'
}
],
framework: 'jasmine',
shardTestFiles : true,
maxSessions : 3,
specs: ['spec.js'],
onPrepare: function() {
return new Promise(function (fulfill, reject) {
browser.waitForAngularEnabled(false);
browser.getCapabilities().then(function (value) {
reportName = value.get('webdriver.remote.sessionid') + '_' +
value.get('browserName') + '_' + Math.floor(Math.random()*1E16);
jasmine.getEnv().addReporter(new Jasmine2HtmlReporter({
savePath: '.test/reports/',
screenshotsFolder: 'images',
consolidate: false,
consolidateAll: false,
filePrefix: reportName + ".html"
})
);
fulfill();
})
});
},
jasmineNodeOpts: {
showColors: true,
defaultTimeoutInterval: 600000
}
};
Drivers used:
chromedriver_2.30
geckodriver-v0.19.1
IEDriverServer3.7.0

Answer 1

The problem with internet explorer was because the driver was not properly installed.
This command helped "webdriver-manager update --ie64"
And the other reason was silly.
The c in multicapabilities was small
Now this works,
multiCapabilities: [{
'browserName' : 'chrome'
},
{
'browserName' : 'firefox'
}
{
'browserName': 'internet explorer',
'version' : '11'
}
],
