I am trying to scrape some text and than compare it in jest except.
My code:
expect(received).toBe(expected) // Object.is equality
Returns:
Expected: Forgot password
Received: {}
describe("login to Synthrone tests", () => {
test("no existed user try", async () => {
browser = await puppeteer.launch(chromeOptions);
const page = await browser.newPage();
await page.goto("https://admin.manager.test-synthrone.com/");
const a = page.evaluate(() =>
document.querySelector(".additional-user-actions").textContent.trim()
);
expect(a).toBe("Forgot password");
});
});

I'm trying to do login at a web page but when I try to do it through Puppeteer it fails.
The code below should redirect with success to https://prenotami.esteri.it/UserArea but it fails and redirect to https://prenotami.esteri.it/Home/Login
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({headless:false, ignoreDefaultArgs: ['--enable-automation']});
const page = await browser.newPage();
await page.goto('https://prenotami.esteri.it/UserArea');
await page.evaluate(() => {
document.querySelector('#login-email').value = "****#gmail.com"
document.querySelector('#login-password').value = "pass***"
document.querySelector('button[type="submit"]').click()
})
})();
As it can be seen, I've tried to disable automation.I also tried to put some delay but I couldn't realize where exactly
SOLVED:
I've changed the code and it works now
const extra = require('puppeteer-extra');
const stealth = require('puppeteer-extra-plugin-stealth')
extra.use(stealth())
extra
.launch({
headless: false,
args: ['--no-sandbox']
})
.then(async browser => {
const page = await browser.newPage();
await page.goto('https://prenotami.esteri.it/');
page.setDefaultNavigationTimeout(30000)
await page.type("#login-email", "*****#gmail.com")
await page.type("#login-password", "*****pass")
await page.click('button[type="submit"]')
await page.waitForNavigation({ waitUntil: 'domcontentloaded' })
await page.goto("https://prenotami.esteri.it/Services/Booking/751")
await page.waitForNavigation({ waitUntil: 'domcontentloaded' })
Hi I am running a puppeteer script which will pre fill the form values and will wait for the value from the command line. Once it receives the value it will enter the value in an input type and submit the form.
I am able to do it using readline(). The problem I'm facing is my script will be waiting for the value which will be provided by an API.
I need to know how to receive value from the API so that my script will use the value to fill the form and continue.
const puppeteer = require('puppeteer');
const readline = require('readline');
async function readLine() {
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
return new Promise(resolve => {
rl.question('Enter username: ', (answer) => {
rl.close();
resolve(answer)
});
});
(async () => {
const browser = await puppeteer.launch({
headless: false,
devtools: false,
ignoreHTTPSErrors: true,
args: [
'--start-fullscreen',
'--window-size=1920,1040',
'--no-sandbox'
]
});
const page = await browser.newPage();
// Set windows height en width
await page.setViewport({
width: 1600,
height: 900
});
await page.goto("www.domain.com/admin");
const userName = await readLine();
await page.focus('#username');
await page.keyboard.type(userName, {delay: 100});
})
This is my code.
My script will be waiting for the value. I need to pass the value to my script. which I will receive from another application. I need to know how to pass the value to my script using an API
I faced on similar problem.
This works for me:
...
const input = await page.$('#id');
await input.evaluate(
(inp, { username })=>{
inp.value = username;
},
{ username: username } // pass params from async function here
)
I am writing automated tests using Jest & Puppeteer for a Front-end application written in Vue.js
So far I managed to write a set of tests, but they all reside in the same file:
import puppeteer from 'puppeteer';
import faker from 'faker';
let page;
let browser;
const width = 860;
const height = 1080;
const homepage = 'http://localhost:8001/brt/';
const timeout = 1000 * 16;
beforeAll(async () => {
browser = await puppeteer.launch({
headless: false, // set to false if you want to see tests running live
slowMo: 30, // ms amount Puppeteer operations are slowed down by
args: [`--window-size=${width},${height}`],
});
page = await browser.newPage();
await page.setViewport({ width, height });
});
afterAll(() => {
browser.close();
});
describe('Homepage buttons', () => {
test('Gallery Button', async () => {
// navigate to the login view
await page.goto(homepage);
await page.waitFor(1000 * 0.5); // without this, the test gets stuck :(
await page.waitForSelector('[data-testid="navBarLoginBtn"]');
await page.click('[data-testid="navBarLoginBtn"]'),
await page.waitForSelector('[data-testid="navBarGalleryBtn"]');
await page.click('[data-testid="navBarGalleryBtn"]'),
// test: check if we got to the gallery view (by checking nr of tutorials)
await page.waitForSelector('.card-header');
const srcResultNumber = await page.$$eval('.card-header', (headers) => headers.length);
expect(srcResultNumber).toBeGreaterThan(1);
}, timeout);
});
describe('Register', () => {
const btnLoginToRegister = '#btn-login-to-register';
const btnRegister = '#btn-register';
const btnToLogin = '#btn-goto-login';
test('Register failed attempt: empty fields', async () => {
// navigate to the register form page via the login button
await page.goto(homepage);
await page.waitForSelector(navLoginBtn);
await page.click(navLoginBtn);
await page.waitForSelector(btnLoginToRegister);
await page.click(btnLoginToRegister);
// test; checking for error messages
await page.waitForSelector(btnRegister);
await page.click(btnRegister);
const errNumber = await page.$$eval('#errMessage', (err) => err.length);
expect(errNumber).toEqual(3);
}, timeout);
test('Register failed: invalid char count, email format', async () => {
// fill inputs
await page.waitForSelector('#userInput');
await page.type('#userInput', 'a');
await page.waitForSelector('#emailInput');
await page.type('#emailInput', 'a');
await page.waitForSelector('#emailInput');
await page.type('#passInput', 'a');
await page.waitForSelector(btnRegister);
await page.click(btnRegister);
// test: check if we 3 errors (one for each row), from the front end validations
const err = await page.$$eval('#errMessage', (errors) => errors.length);
expect(err).toEqual(3);
}, timeout);
test('Register: success', async () => {
await page.click('#userInput', { clickCount: 3 });
await page.type('#userInput', name1);
await page.click('#emailInput', { clickCount: 3 });
await page.type('#emailInput', email1);
await page.click('#passInput', { clickCount: 3 });
await page.type('#passInput', password1);
await page.waitForSelector(btnRegister);
await page.click(btnRegister);
// test: check if go to login link appeared
await page.waitForSelector(btnToLogin);
await page.click(btnToLogin);
// await Promise.all([
// page.click(btnToLogin),
// page.waitForNavigation(),
// ]);
}, timeout);
test('Register failed: email already taken', async () => {
// navigate back to the register form
await page.waitForSelector(btnLoginToRegister);
await page.click(btnLoginToRegister);
await page.click('#userInput');
await page.type('#userInput', name2);
await page.click('#emailInput');
await page.type('#emailInput', email1); // <- existing email
await page.click('#passInput');
await page.type('#passInput', password2);
await page.click(btnRegister);
const err = await page.$eval('#errMessage', (e) => e.innerHTML);
expect(err).toEqual('Email already taken');
}, timeout);
});
I would like to be able to have a single test file that does the beforeAll and afterAll stuff, and each test suite: HomepageButtons, Register, etc. to reside in it's own test file. How would I be able to achieve this?
I've tried splitting tets into:
testsUtils.js that would contain the beforeAll and afterAll hooks and code but it doesn't guarantee that it runs when it needs: the beforeAll code to fire before all other test files and the afterAll code to fire after all the test files finished.
Sorry, I'd rather comment on your question, but I don't have reputation for that. Anyway, I think that you are looking for something like a "global beforeAll" and "global afterAll" hooks, right? Jest has it alread. It's called "globalSetup" and "globalTeardown".
Take a look at globalSetup. Excerpt:
This option allows the use of a custom global setup module which
exports an async function that is triggered once before all test
suites.
The Global Teardown one goes the same.
I think you'll have a headache trying to get a reference to the page or browser in globalSetup/globalTeardown and I confess that I never try this. Maybe the answer for that problem (if you have it) is on this page, under "Custom example without jest-puppeteer preset section.
Also there is a repo that tries to facilitate Jest + Puppeteer integration. Maybe you find it util: repo.
Good luck. :)
I wrote a unit test for some Axios calls in my component. I verified the success path, where the call resolves successfully, but I am not able to verify the failure path, where the call rejects. How do I use mocks to verify this?
Here's a snippet of my FetchImage.vue component:
methods: {
preparedFetch() {
axios.get(this.imageurl).then(result => {
this.imageInformation.title = result.data.title;
this.imageInformation.copyright = result.data.copyright;
this.imageInformation.detailExplanation = result.data.explanation;
this.imageInformation.date = result.data.date;
this.imageInformation.urlinfo = result.data.url;
this.resultArrived = true;
this.$emit('imagefetched',this.imageInformation);
})
.catch( error => {
this.errorMessage = "Information not found";
this.resultArrived = true;
});
}
}
And my test for when the call rejects (for an invalid URL):
describe('Invalid response',async () => {
beforeEach(() => {
axios.get.mockClear();
axios.get.mockReturnValue(Promise.reject({}));
});
it('Invalid URL verfication', async () => {
// Given
const result = {
errorMessage : "Information not found",
resultArrived : true,
fetchStatus : true
};
// Fetch the error result
axios.get.mockReturnValue(Promise.resolve(result));
const fetchwrapper = mount(FetchImage);
fetchwrapper.vm.imageurl = "https://invalid.request.gov";
fetchwrapper.vm.preparedFetch();
await fetchwrapper.vm.$nextTick();
// Validate the result
expect(axios.get).not.toHaveBeenCalledWith('https://api.nasa.gov/planetary/apod?api_key=vME6LAMD7IhEiy7rDmjfIaG6MhiKbu1MNIqxtqd1');
expect(axios.get).toHaveBeenCalledWith("https://invalid.request.gov");
expect(axios.get).toHaveBeenCalledTimes(1);
expect(fetchwrapper.vm.errorMessage.length).not.toEqual(0);
expect(fetchwrapper.vm.errorMessage).toBe("Information not found");
});
});
Your catch block isn't running because the mock return value is using Promise.resolve() when it actually should be Promise.reject():
describe('Invalid response',async () => {
it('Invalid URL verfication', async () => {
// axios.get.mockReturnValue(Promise.resolve(result)); // DON'T DO THIS
axios.get.mockReturnValue(Promise.reject(result));
});
});
You have to reject the value by using the built-in jest method.
describe('Invalid response', async () => {
it('Invalid URL verfication', async () => {
axios.get.mockRejectedValue(result);
});
});
I'm currently working with Puppeteer and Jest for end-to-end testing, for my tests to work I always need to run a login tests, but I don't know and haven't been able to find out how to export my tests so I can reuse them.
To conclude: I'm looking for a way to reuse all of my tests inside the describe by exporting them to a different file and reusing them in a beforeAll in the new files.
The complete set of login tests is below:
describe("homepage and login tests", homepageTests = () => {
test("front page loads", async (done) => {
await thePage.goto('http://localhost:3000');
expect(thePage).toBeDefined();
done();
});
test("Login button is present", async (done) => {
theLoginButton = await thePage.$("#login-button");
expect(theLoginButton).toBeDefined();
done();
})
test("Login works", async (done) => {
//the following code runs inside the popup
await theBrowser.on('targetcreated', async (target) => {
const thePopupPage = await target.page();
if (thePopupPage === null) return;
//get the input fields
const usernameField = await thePopupPage.waitFor('input[name=login]');
const passwordField = await thePopupPage.waitFor("input[name=password]");
const submitButton = await thePopupPage.waitFor('input[name=commit]');
//validate input fields
expect(usernameField).not.toBeNull();
expect(passwordField).not.toBeNull();
expect(submitButton).not.toBeNull();
//typing and clicking
await thePopupPage.waitFor(300)
await usernameField.type("USER");
await passwordField.type("PASSWORD");
await submitButton.click();
done();
})
try {
//wait for login button on homepage
theLoginButton = await thePage.waitFor('#login-button');
expect(theLoginButton).toBeDefined();
//click on login
await thePage.waitFor(200);
await theLoginButton.click();
} catch (e) { console.log(e) }
})
test("Arrive on new page after login", async () => {
//resultsButton is only shown for logged in users.
const resultsButton = await thePage.$("#resultsButton");
expect(resultsButton).toBeDefined();
})
Create a separate file name test.js
//test.js
export async function fn1(args){
// your commands
}
//file.test.js
import {fn1} from 'test.js'
describe('test 1 ', () => {
test("test", async () => {
try {
await fn1(args);
} catch (err) {
console.log('There are some unexpected errors: ' + err);
}
},5000);
});
I have the same issue and the above method will work out for you.
