cypress-social-logins
cypress authentication flows using social network providers
About
This Cypress library makes it possible to perform third-party logins (think oauth) for services such as GitHub, Google or Facebook.
It does so by delegating the login process to a puppeteer
flow that performs the login and returns the cookies for the application under test so they can be set by the calling Cypress flow for the duration of the test.

Usage
- Call the declared task with a set of options for the social login flow interaction
- Set the cookies for the test flow with the help of
Cypress.Cookies.defaults
- Copy over all or some (or none) of the local & session storage objects from puppeteer to local instance
cy.clearCookies()
return cy.task('GoogleSocialLogin', socialLoginOptions).then(({cookies,lsd,ssd}) => {
const cookie = cookies.filter(cookie => cookie.name === cookieName).pop()
if (cookie) {
cy.setCookie(cookie.name, cookie.value, {
domain: cookie.domain,
expiry: cookie.expires,
httpOnly: cookie.httpOnly,
path: cookie.path,
secure: cookie.secure
})
Cypress.Cookies.defaults({
whitelist: cookieName
})
}
// ssd contains session storage data (window.sessionStorage)
// lsd contains local storage data (window.localStorage)
cy.window().then(window => {
Object.keys(ssd).forEach(key => window.sessionStorage.setItem(key, ssd[key]));
Object.keys(lsd).forEach(key => window.localStorage.setItem(key, lsd[key]));
});
})
Options passed to the task include:
Option name | Description | Example |
---|---|---|
username | ||
password | ||
loginUrl | The URL for the login page that includes the social network buttons | https://www.example.com/login |
args | string array which allows providing further arguments to puppeteer | ['--no-sandbox', '--disable-setuid-sandbox'] |
headless | Whether to run puppeteer in headless mode or not | true |
logs | Whether to log interaction with the loginUrl website & cookie data | false |
loginSelector | A selector on the page that defines the specific social network to use and can be clicked, such as a button or a link | 'a[href="/auth/auth0/google-oauth2"]' |
postLoginSelector | A selector on the post-login page that can be asserted upon to confirm a successful login | '.account-panel' |
preLoginSelector | a selector to find and click on before clicking on the login button (useful for accepting cookies) | '.ind-cbar-right button' |
loginSelectorDelay | delay a specific amount of time before clicking on the login button, defaults to 250ms. Pass a boolean false to avoid completely. | 100 |
getAllBrowserCookies | Whether to get all browser cookies instead of just ones with the domain of loginUrl | true |
isPopup | boolean, is your google auth displayed like a popup | true |
popupDelay | number, delay a specific milliseconds before popup is shown. Pass a falsy (false, 0, null, undefined, '') to avoid completely | 2000 |
cookieDelay | number, delay a specific milliseconds before get a cookies. Pass a falsy (false, 0, null,undefined,'') to avoid completely | 100 |
Install
Install the plugin as a dependency
npm install --save-dev cypress-social-logins
Import the plugin
Import the cypress-social-logins
plugin definition for the specific social
network login you are interested of, and declare a task that performs the
login.
Example:
const {GoogleSocialLogin} = require('cypress-social-logins').plugins
module.exports = (on, config) => {
on('task', {
GoogleSocialLogin: GoogleSocialLogin
})
}
Using the social login
Once the Cypress task is defined we can expose a test case that makes use of it. The task will accept an options object with the username, password and other configurations that need to be specified so that the task can navigate through the page properly.
Once the task has completed it will return the list of cookies from the new
page. Most likely that these cookies need to be set for the rest of the
sessions in the test flow, hence the example code showing the case for
Cypress.Cookies.defaults
.
describe('Login', () => {
it('Login through Google', () => {
const username = Cypress.env('googleSocialLoginUsername')
const password = Cypress.env('googleSocialLoginPassword')
const loginUrl = Cypress.env('loginUrl')
const cookieName = Cypress.env('cookieName')
const socialLoginOptions = {
username,
password,
loginUrl,
headless: true,
logs: false,
loginSelector: 'a[href="/auth/auth0/google-oauth2"]',
postLoginSelector: '.account-panel'
}
return cy.task('GoogleSocialLogin', socialLoginOptions).then(({cookies}) => {
cy.clearCookies()
const cookie = cookies.filter(cookie => cookie.name === cookieName).pop()
if (cookie) {
cy.setCookie(cookie.name, cookie.value, {
domain: cookie.domain,
expiry: cookie.expires,
httpOnly: cookie.httpOnly,
path: cookie.path,
secure: cookie.secure
})
Cypress.Cookies.defaults({
whitelist: cookieName
})
}
})
})
})
Troubleshooting
Timeout while trying to enter username
Make sure you are providing the plugin with the username or password in the options when instantiating it. If you're passing it via environment variables then the plugin will look for these two: CYPRESS_googleSocialLoginUsername
and CYPRESS_googleSocialLoginPassword
If your application uses popup auth, make sure you are providing isPopup: true
configuration parameter.
Failed to launch the browser process
If you're getting an error on a Linux server such as:
Error: Failed to launch the browser process!
[768:768:0423/165641.025850:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.
TROUBLESHOOTING:
You should pass the argument --no-sandbox
to the plugin as extra arguments.
