Protractor + jasmine : run same spec twice with different params: - jasmine

Question

Hi this is my config :
exports.config = {
allScriptsTimeout: 11000,
specs: [
'./e2e/xyz/xyz.e2e-spec.ts',
],
multiCapabilities: [
{
browserName: 'chrome',
chromeOptions: {
args: ['--headless', '--disable-gpu', '--window-size=1024x768', '--no-sandbox']
}
}
/* Failing in Jeniks, TODO : need to fix this,
{
browserName: 'firefox',
firefoxOptions: {
args: ['--headless']
},
'moz:firefoxOptions': {
args: ['--headless']
}
}
*/
],
directConnect: true,
chromeOnly: false,
baseUrl: nconf.get('BASE_URL'),
framework: 'jasmine',
jasmineNodeOpts: {
showColors: true,
defaultTimeoutInterval: 120000,
includeStackTrace : true,
print: function () { }
},
restartBrowserBetweenTests: false,
useAllAngular2AppRoots: true,
onPrepare: function () {
require('ts-node').register({
project: './e2e/tsconfig.json'
});
let SpecReporter = require('jasmine-spec-reporter').SpecReporter;
jasmine.getEnv().addReporter(new SpecReporter({displayStacktrace: 'spec'}));
},
params: {
login: {
username: nconf.get('USERNAME'),
password: nconf.get('PASSWORD'),
username_d: nconf.get('D_USERNAME'),
password_d: nconf.get('D_PASSWORD')
},
sddc_id: nconf.get('SDDC_ID'),
org_id: nconf.get('ORG_ID'),
env: nconf.get('env'),
d_sddc_id: nconf.get('D_SDDC_ID')
}
Now I want to call xyz.e2e-spec.ts twice for different usernames and passwords. Is there a way to run "describe('SOme work', () => {). twice in xyz.e2e-spec.ts?. I mean for loop wont works on this since describe is a function.
