How to run spec.js files in Firefox and Chrome conditionally and in none parallel mode in Protractor with Jasmine .

Test scenario- I want to run some of spec.js files in firefox and some of spec.js files in Chrome The tests must be run in none parallel mode and first run in a one browser type and then in the other browser type . How do I achieve that ?

Steps-

In cmd type webdriver-manager start

After that open a cmd line as Admin and go to config.js file location and enter the below command (twobrowsersfortwospecsconfig.js is my file name )

protractor twobrowsersfortwospecsconfig.js

In the config.js , I have mentioned draganddrop.spec.js to run in Firefox while iframes.spec.js to be run in Chrome .

So the spec.js will be executed as per the requirement .

//protractor twobrowsersfortwospecsconfig.js
exports.config = {
framework: 'jasmine',
directConnect: false,
multiCapabilities: [{
browserName: 'firefox',
'moz:firefoxOptions': {
args: ['--verbose'],
binary: 'C:/Program Files/Mozilla Firefox/firefox.exe'
//Need to start cmd via admin mode to avoid permission error
},
specs: ['src/com/sam/scriptjs/draganddrop.spec.js']
},
{
browserName : 'chrome',
chromeOptions: {
args: [ "--start-maximized" ]
},
specs: ['src/com/sam/scriptjs/iframes.spec.js']
}],
maxSessions: 1,//To run in sequential mode so first Firefox then chrome
//without max session it will open two windows at the same time for both browsers
seleniumAddress: 'http://localhost:4444/wd/hub'
}

My spec.js files are in src/com/sam/scriptjs folder.

draganddrop.spec.js

//draganddrop.spec.js
describe('drag and drop trial', function() {
//Each single it function is a test script
it('first spec', function() {
browser.driver.get('https://codef0rmer.github.io/angular-dragdrop/#!/');
expect(browser.getTitle()).toEqual('Drag and Drop for AngularJS');
});
it('Drag and drop', function() {
var from=element(by.model('list1'));
var to=element(by.model('list2'));
//drag and drop source  to Destination
// browser.actions().dragAndDrop(from,to).perfrom();
browser.actions().mouseDown(from).mouseMove(to).mouseUp().perform();
browser.sleep(7500);
});
})

iframes.spec.js which is the other spec.js

//iframes.spec.js
describe('Iframe example', function() {
//Each single it function is a test script
it('Iframe handling', function() {
browser.driver.ignoreSynchronization = true;
browser.waitForAngularEnabled(false);
browser.driver.manage().window().maximize();
browser.driver.get('http://demo.automationtesting.in/Frames.html');
expect(browser.getTitle()).toEqual('Frames');
});
it('Iframe handling', function() {
//right click near the element if it show view frame source it means it'sinside of an iframe
browser.switchTo().frame(0);//we can give name or index
//sendkeys inside of an element in an iframe
element(by.xpath('//input[@type="text"]')).sendKeys('Hi element inside of a one iframe');
// switch back to main contain
browser.switchTo().defaultContent();
//click element that not in any iframe
element(by.linkText('Home')).click();
});
})
