I have encountered a wierd redirect in my cypress tests that occur seemingly randomly and I would really appreciate some help on why this is happening. As you can see in my code there's no new route that should happen here:
it('should click on my account menu', () => {
cy.getByTranslationKey('My account').click({timeout: 5000})
});
it('should click on Account Settings in the account menu', () => {
cy.get('.ReactCollapse--content').should('be.visible')
cy.getByTranslationKey('Account settings')
.should('be.visible', {timeout: 5000})
.click();
});
it('should display the email in the form', () => {
cy.get('input[name="person.email"]')
.should('be.visible')
.should('have.value', email);
});
As you can see there's a "new route" here:

Each
it('', ()=>{});
construct will reinstantiate from scratch your page if you didn't set a baseUrl.

I'm working on a Cypress test for the Polish Wikipedia plugin, and I have this code in my cypress test:
Cypress.Commands.overwrite('visit', (orig, path, options) => {
return orig(`https://pl.wikipedia.org/${path}`);
});
Cypress.Commands.add('login', (pass) => {
cy.visit('/w/index.php?title=Specjalna:Zaloguj');
cy.get('#wpName1').type('<username>');
cy.get('#wpPassword1').type(pass);
cy.get('#userloginForm form').submit();
});
Cypress.Commands.add('dark_vector_wait', (pass) => {
cy.get('.vector-menu-content-list > li:nth-child(7)', { timeout: 10000 }).should('be.visible');
});
And in my spec:
describe('dark vector test', () => {
beforeEach('login', () => {
cy.login(Cypress.env('WIKI_PASSWORD'));
});
it('test discussion', () => {
cy.visit('/wiki/Dyskusja_wikipedysty:<username>');
cy.dark_vector_wait();
cy.matchImageSnapshot('discussion');
});
it('testing-page page', () => {
cy.visit('/wiki/Wikipedysta:<username>/testing-page');
cy.dark_vector_wait();
cy.matchImageSnapshot('testing-page');
});
});
And the second test is failing because as soon as Cypress type the password it automatically submits a form so cy.get('#userloginForm form').submit(); is executing after Cypress visits the home page (default redirect) and fail to find a form.
What's wrong? Why does Cypress auto-submit a form after a second time? This is not what Wikipedia is doing since the login form doesn't have any JavaScript code and you need to click login to be able to login to Wikipedia.
EDIT:
I've tried to
Use BaseURL and remove overwrite of visit.
Add type('{enter}'), but this only shows an error: cy.type() failed because this element is detached from the DOM.
EDIT 2
This is the screenshot of the action taken by cypress, second test has a page load without {enter} action and without form submit.
The problem is in Cypress.Commands.overwrite('visit').
You pass the parameter with a leading slash '/wiki/Dyskusja_wikipedysty:<username>' but concatinate to base which also has a trailing slash https://pl.wikipedia.org/${path}, so now the full path is
https://pl.wikipedia.org//wiki/Dyskusja_wikipedysty:<username>
If you set baseUrl in configuration, Cypress sorts it out for you
cypress.config.js
const { defineConfig } = require('cypress')
module.exports = defineConfig({
e2e: {
setupNodeEvents(on, config) {
// implement node event listeners here
},
baseUrl: 'https://pl.wikipedia.org'
}
})
Then remove the Cypress.Commands.overwrite('visit').
With these changes, I was able to pass both tests.
Using cy.session()
The problem might be one specific to locality, I do not have any steps missing in the Cypress log.
You can try adding a session cache so that the first login is re-used.
Cypress.Commands.add('login', (pass) => {
cy.session('login', () => { // login occurs only once
// credentials are cached
cy.visit('/w/index.php?title=Specjalna:Zaloguj');
cy.get('#wpName1').type('Jack Bosko');
cy.get('#wpPassword1').type(pass);
cy.get('#userloginForm form').submit();
// for good measure, confirm login was successful
// by checking for your name on the page
cy.contains('span', 'Jack Bosko')
})
})
So the problem was the weird IME keyboard that is part of MediaWiki. I somehow got it enabled on my system even when I was not logged in. Maybe added globally with cookies or something.
I noticed that keyboard when I was asking questions on the MediaWiki support page.
This is not related to Cypress. I'm investigating why the keyboard is there, and why clean environment it.
I want to test every page of my site (Vue/Nuxt), but API calls should be mocked.
For that there is intercept() function (route() in previous Cypress versions):
homepage.spec.js:
describe('home page', () => {
before(() => {
cy.intercept('**/user-data', { fixture: 'user.json' })
cy.visit('http://localhost:8080')
})
it('renders header, () => {
cy.contains('#header', 'test');
});
// some other tests for homepage
});
Cool, it works, but I have this specific API call (getting logged user info) on every page. I don't want to repeat this intercept code in every test file, for example contact.spec.js. I cannot find a way to set this intercept globally? What is the correct way to mocking axios?
I'm visiting a page which is fetching data Asynchronously (multiple XHR requests), and then asserting if a certain DOM element is visible/exists in the page.
So far I was only able to get the page and the data fetched with using cy.wait() either with an arbitrary time, or by aliasing the actual request, and using the promise-like syntax to make sure my cy.get() is done after the XHR response has completed.
Here is what doesn't work:
before(() => {
cy.login();
cy.server();
cy.route('/v0/real-properties/*').as('getRealPropertyDetails');
cy.visit('/real-properties/1/real-property-units-table');
});
beforeEach(() => {
Cypress.Cookies.preserveOnce('platform_session');
});
after(() => {
cy.clearCookies();
});
context('when viewport is below 1367', () => {
it('should be closed by default', () => {
cy.wait('#getRealPropertyDetails'); // the documentation says this is the way to go
sSizes.forEach((size) => {
cy.viewport(size[0], size[1]);
cy.get('.v-navigation-drawer--open.real-property-details-sidebar').should('not.exist');
});
});
Adding cy.wait(1000); in the before() or beforeEach() hooks also works, but this is not really an acceptable solution.
What works, but not sure if this is the way to do this (I would have to add this for every page, would be quite annoying) :
it('should be closed by default', () => {
cy.wait('#getRealPropertyDetails').then(() => {
sSizes.forEach((size) => {
cy.viewport(size[0], size[1]);
cy.get('.real-property-details-sidebar').should('not.be.visible');
});
});
});
I see that you have browser reloads there (beforeEach), which could potentially wipe out the route spy, but not sure why cy.wait().then would work. I would try switching from before to beforeEach though, creating things once is always trickier than letting them be created before each test
I just entered the world of testing with puppeteer and jest, and I was wondering what the best practice was in terms of folder architecture and logic.
I've never done testing before and I think I'm getting a little lost in the different principles and concepts and how it all fits together.
I learned to do my tests based on the page-object model, so I have classes for each of my pages, but also for each of my modules ( or components ). For example, in my application, the header or the login modal are components.
Then I have a test file per page or per component.
(for example the landingPage.tests.js file, which uses the model of the LandingPage class in the LandingPage.js file)
Here is a concrete example:
I have different login cases and I'd like to test them all. For example I want to test to connect with a "normal" user, for which the process is simply login then password. Then I need to test with a user who has activated 2FA, or with a user from a company that uses SSO.
I first thought about putting my different tests in authentication.tests.js, in different describe blocks, thinking it would open a new tab each time, but it doesn't... I use puppeteer in incognito mode to make sure each tab is an isolated session.
So my questions are:
Where is the best place to do these test suites?
Am I supposed to have test files that "describe" the pages ( for example, the button must be present, such text must be here etc) and also have "scenario type" test file ( a set of contextual actions to a user, like for my different login cases) ?
Here is authentication.tests.js, in which I would like to tests all my different ways of logging in :
import HeaderComponent from "../../../pages/components/HeaderComponent";
import AuthenticationComponent from "../../../pages/components/AuthenticationComponent";
import LandingPage from "../../../pages/landing/LandingPage";
import {
JEST_TIMEOUT,
CREDENTIALS
} from "../../../config";
describe('Component:Authentication', () => {
let headerComponent;
let authenticationComponent;
let landingPage;
beforeAll(async () => {
jest.setTimeout(JEST_TIMEOUT);
headerComponent = new HeaderComponent;
authenticationComponent = new AuthenticationComponent;
landingPage = new LandingPage;
});
describe('Normal login ', () => {
it('should click on login and open modal', async () => {
await landingPage.visit();
await headerComponent.isVisible();
await headerComponent.clickOnLogin();
await authenticationComponent.isVisible();
});
it('should type a normal user email adress and validate', async () => {
await authenticationComponent.typeUsername(CREDENTIALS.normal.username);
await authenticationComponent.clickNext();
});
it('should type the correct password and validate', async () => {
await authenticationComponent.typePassword(CREDENTIALS.normal.password);
await authenticationComponent.clickNext();
});
it('should be logged in', async () => {
await waitForText(page, 'body', 'Success !');
});
});
describe('SSO login ', () => {
// todo ...
});
});
Thank you and sorry if it sounds confusing, like I said I'm trying to figure out how it all fits together.
Regarding the folder structure, Jest will find any files according to the match config, basically anything called *.spec.js or *.test.js. Looks like you know that already.
What that means is the folder structure is completely up to you. Some people like to have the tests for components in the same folders as the components themselves. Personally I prefer to have all the tests in one folder as it makes the project look cleaner.
The other benefit of having all the tests in one folder is that you can then start to distinguish between the types of tests. Component tests check that pure components render and operate as expected. You don't need Puppeteer for this, use snapshots if you're in a React app. Puppeteer is good for integration tests that navigate through so-called 'happy paths', login, signup, add to cart etc., using a headless Chromium browser.
To answer the specific problem you have been having with Jest / Puppeteer on a new page for each test:
//keep a reference to the browser
let browser
//keep a reference to the page
let page
// open puppeteer before all tests
beforeAll(async () => {
browser = await puppeteer.launch()
})
// close puppeteer after all tests
afterAll(async () => {
await browser.close()
})
// Get a new page for each test so that we start fresh.
beforeEach(async () => {
page = await browser.newPage()
})
// Remember to close pages after each test.
afterEach(async () => {
await page.close()
})
describe('Counter', () => {
// "it" blocks go here.
})
Hope that helps a bit.
This is regarding detox e2e tests.
I am running my tests, each under an it('xx', async => { await...});
The tests are scripted in such a way that 1st test would log in, 2nd test would do something on homepage, 3 rd test would navigate from homepage to other pages and so on.
The issue here is, as soon as my first test executes, the app is getting logged out and all the consecutive tests are failing.
But when I include all steps(right from login to the desired functionality) in every test, the suite is working properly.
I would like to know why is this happening. Is there any connection with async function?
One of the gotchas for using Detox is that the sample test specification uses a beforeEach and there is a tendency to copy verbatim examples that we are given, some times missing out things that either need to be removed or should be added.
In this particular case in the beforeEach there is the call await device.reloadReactNative(); this command reloads the device as if you had pressed CMD+R (on iOS) or RR (on Android). This means that items that have been saved to state are lost and the application is pretty much returned to its initial state.
Check your code for the offending line, you can see it in example provided below. If you remove this line then it will stop reloading React Native on your device before each test.
example.spec.js
https://github.com/wix/Detox/blob/master/examples/demo-react-native/e2e/example.spec.js
describe('Example', () => {
beforeEach(async () => {
await device.reloadReactNative(); // <- this is the problem
});
it('should have welcome screen', async () => {
await expect(element(by.id('welcome'))).toBeVisible();
});
it('should show hello screen after tap', async () => {
await element(by.id('hello_button')).tap();
await expect(element(by.text('Hello!!!'))).toBeVisible();
});
it('should show world screen after tap', async () => {
await element(by.id('world_button')).tap();
await expect(element(by.text('World!!!'))).toBeVisible();
});
});
