I have a test that downloads excel files from a site and the test also requires to check the sheetnames of the excel file. I already got passed on everything in my local but in CircleCI it's returning as 'File not found' (I used this as an error message if file is missing). It cannot locate the file. Is it possible to this in CircleCI?
Here is the code:
test.js
cy.get('#transferTestUrl').then((finalLink) => {
cy.get('#documentPassword').then((password) => {
const linkBody = { username: testdata.credentials.adminAccountInternalTest,
password: password,
transferTestLink: finalLink,
}
cy.origin('transfer-develop.test.net',{ args: linkBody }, ({ username, password,transferTestLink })=>{
cy.visit(transferTestLink,{
auth:{
username: username,
password: password
}
})
// to prevent Cypress from loading indefinitely when downloading, only works in Chrome
cy.window().document().then(function (doc) {
doc.addEventListener('click', () => {
setTimeout(function () { doc.location.reload() }, 5000)
})
cy.get('#downloadButton').click({force:true})
cy.wait(4000)
})
})
})
})
cy.get('span').contains('courses').invoke('text').then((title) => {
cy.wrap(title).as('initialDocumentTitle')
cy.get('#initialDocumentTitle').then((initialTitle) => {
var convertedTitle = initialTitle.replaceAll(':', "_")
cy.wrap(convertedTitle).as('downloadedDocumentTitle')
cy.wait(10000)
})
})
cy.get('#courseNameArray').then((courseNamesArray) => {
cy.log(courseNamesArray)
cy.get('#downloadedDocumentTitle').then((documentTitle) => {
//start of reading files from Excel
var removeSpace = documentTitle.replace(/\s/g, '')
var excelFilePath = "../CreateAutomatedTests/cypress/downloads/"+removeSpace
cy.verifyDownload(removeSpace, { interval: 600 })
cy.wrap(excelFilePath).as('filePath')
cy.get('#filePath').then((filePath) => {
cy.task('checkExcelSheetContents', { filePath }).then((contents) => {
cy.log(contents)
expect(contents).to.deep.equal(courseNamesArray)
})
})
})

I'm trying to test this site https://store.google.com/regionpicker and when I select a region (US) for example and get redirected to this url: https://store.google.com/us/?hl=en-US®ionRedirect=true I get an app error in the console, and cypress fails to continue
I added this code to handle exceptions before the test starts, but it doesn't catch it:
cy.on('uncaught:exception', () => {
return false
})
full code:
describe('Purchase a device from Google Store', () => {
const LOCATORS = {
devicesMenu: '[id="desktop-products"]',
headerContainer: '.header-container',
regionTitle: '.region-title',
dialog: '[role="dialog"]',
button: '[role="button"]',
}
before(() => {
cy.visit('/')
})
beforeEach(() => {
Cypress.on('uncaught:exception', () => {
return false
})
})
it('Purchase device', () => {
let region = 'United States'
let urlToVerify = 'us/?hl=en-US®ionRedirect=true'
cy.contains(LOCATORS.regionTitle, region)
.click().then(() => {
cy.get(LOCATORS.dialog).within(() => {
cy.contains('Continue')
.click({ force: true }).then(() => {
cy.url()
.should('include', urlToVerify)
})
})
})
})
})
You can test the URL in an event handler for the url:changed event.
The basic problem seems to be that it's not possible to take Cypress to https://store.google.com, the browser ends up with URL about:blank.
But by adding a listener to url:changed you can at least verify that the correct URL was attempted.
it('redirects after region select', () => {
const region = 'United States'
const urlToVerify = 'us/?hl=en-US®ionRedirect=true'
cy.on('url:changed', (url) => {
expect(url).to.include(urlToVerify) // use chai to assert
})
cy.contains(LOCATORS.regionTitle, region).click()
cy.get(LOCATORS.dialog).within(() => {
cy.contains('Continue').click({ force: true })
})
})
I am new to Cypress. How to read data from excel files using Cypress? Searched in google but could not find useful answers.
In cypress you can create cypress task to read xlsx file with SheetJS library.
Usage
cypress\integration\read-xlsx.spec.js
context('Xlsx file', () => {
it('Read excel file', () => {
cy.task('readXlsx', { file: 'my-excel.xlsx', sheet: "Sheet1" }).then((rows) => {
expect(rows.length).to.equal(543)
// expect(rows[0]["column name"]).to.equal(11060)
})
})
})
Need to install xlsx
$ npm install xlsx
Create read excel fuction
cypress\plugins\read-xlsx.js
const fs = require('fs');
const XLSX = require('xlsx');
const read = ({file, sheet}) => {
const buf = fs.readFileSync(file);
const workbook = XLSX.read(buf, { type: 'buffer' });
const rows = XLSX.utils.sheet_to_json(workbook.Sheets[sheet]);
return rows
}
module.exports = {
read,
}
Use function as Cypress task (plugin)
cypress\plugins\index.js
const readXlsx = require('./read-xlsx')
module.exports = (on, config) => {
on('task', {
'readXlsx': readXlsx.read
})
}
Here is an instruction how to use excel as source for cypress tests https://medium.com/#you54f/dynamically-generate-data-in-cypress-from-csv-xlsx-7805961eff55
First you need to conver your xlsx file to json with Xlsx
import { writeFileSync } from "fs";
import * as XLSX from "xlsx";
try {
const workBook = XLSX.readFile("./testData/testData.xlsx");
const jsonData = XLSX.utils.sheet_to_json(workBook.Sheets.testData);
writeFileSync(
"./cypress/fixtures/testData.json",
JSON.stringify(jsonData, null, 4),
"utf-8"
);
} catch (e) {
throw Error(e);
}
Then import json file and loop over each row and use the data in the way you want. In this example it tries to log in to a system.
import { login } from "../support/pageObjects/login.page";
const testData = require("../fixtures/testData.json");
describe("Dynamically Generated Tests", () => {
testData.forEach((testDataRow: any) => {
const data = {
username: testDataRow.username,
password: testDataRow.password
};
context(`Generating a test for ${data.username}`, () => {
it("should fail to login for the specified details", () => {
login.visit();
login.username.type(data.username);
login.password.type(`${data.password}{enter}`);
login.errorMsg.contains("Your username is invalid!");
login.logOutButton.should("not.exist");
});
});
});
});
For me the first answer pretty much worked. But i had to make a small fix.
Use function as Cypress task (plugin)
cypress/plugins/index.js
const readXlsx = require('./read-xlsx')
module.exports = (on, config) => {
on('task', {
'readXlsx': readXlsx.read
})
}
when i used this code i got the below error in cypress.
CypressError
cy.task('log') failed with the following error:
The task 'log' was not handled in the plugins file. The following tasks are registered: readXlsx
and the below fix worked
const readXlsx = require('./read-xlsx')
module.exports = (on, config) => {
on('task', {
'readXlsx': readXlsx.read,
log (message) {
console.log(message)
return null
}
})
}
I am trying to deploy a MERN app in Heroku. My passport.js file is like below
const Strategy = require('passport-jwt').Strategy;
const ExtractJwt = require('passport-jwt').ExtractJwt;
const User = require('../my-app/api/models/User');
module.exports = passport => {
var opts = {};
opts.jwtFromRequest = ExtractJwt.fromAuthHeaderAsBearerToken();
opts.secretOrKey = 'SECRET';
passport.use(new Strategy(opts, (payload, done) => {
User.findOne({ _id: payload._id })
.then(user => {
if (!user) {
return done( null, false )
} else {
return done( null, user )
}
})
.catch(error => {
console.log(error)
return done(error);
})
}))
}
I am getting below error
My file structure is like below
The path is wrong, and cannot be found.
Try:
const User = require('./api/models/User');
My specs are behaving weirdly in that when I run the tests alone, they pass. However, when I run the test suite all together, the failure tests still continue to use the success axios mock instead of using the correct failing http axios mock. This results in my tests failing. Am I missing something for isolating the 2 mocks from each other in the different portions of code?

Found the issue!
The it() blocks for the success case were not using the done callback causing the afterEach() moxios.uninstall() to be called prematurely and not resetting the requests after the call was complete. Fixing this, and now all the tests pass.
I have been playing with rxjs and redux-observable for the last few days and have been struggle to find a way to a test for Observable.ajax. I have the following epic which create a request to https://jsonplaceholder.typicode.com/,
export function testApiEpic (action$) {
return action$.ofType(REQUEST)
.switchMap(action =>
Observable.ajax({ url, method })
.map(data => successTestApi(data.response))
.catch(error => failureTestApi(error))
.takeUntil(action$.ofType(CLEAR))
)
}
where,
export const REQUEST = 'my-app/testApi/REQUEST'
export const SUCCESS = 'my-app/testApi/SUCCESS'
export const FAILURE = 'my-app/testApi/FAILURE'
export const CLEAR = 'my-app/testApi/CLEAR'
export function requestTestApi () {
return { type: REQUEST }
}
export function successTestApi (response) {
return { type: SUCCESS, response }
}
export function failureTestApi (error) {
return { type: FAILURE, error }
}
export function clearTestApi () {
return { type: CLEAR }
}
The code works fine when runs in browser but not when testing with Jest.
I have try,
1) Create a test based on https://redux-observable.js.org/docs/recipes/WritingTests.html. The store.getActions() returns only { type: REQUEST }.
const epicMiddleware = createEpicMiddleware(testApiEpic)
const mockStore = configureMockStore([epicMiddleware])
describe.only('fetchUserEpic', () => {
let store
beforeEach(() => {
store = mockStore()
})
afterEach(() => {
epicMiddleware.replaceEpic(testApiEpic)
})
it('returns a response, () => {
store.dispatch({ type: REQUEST })
expect(store.getActions()).toEqual([
{ type: REQUEST },
{ type: SUCCESS, response }
])
})
})
2) Create a test based on Redux-observable: failed jest test for epic. It returns with
Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL.
it('returns a response', (done) => {
const action$ = ActionsObservable.of({ type: REQUEST })
const store = { getState: () => {} }
testApiEpic(action$, store)
.toArray()
.subscribe(actions => {
expect(actions).to.deep.equal([
{ type: SUCCESS, response }
])
done()
})
})
Can someone point me out what is the correct way to test Observable.ajax ?
I would follow the second example, from StackOverflow. To make it work you'll need to make some minor adjustments. Instead of importing Observable.ajax in your epic file and using that reference directly, you need to use some form of dependency injection. One way is to provide it to the middleware when you create it.
import { ajax } from 'rxjs/observable/dom/ajax';
const epicMiddleware = createEpicMiddleware(rootEpic, {
dependencies: { ajax }
});
The object we passed as dependencies will be give to all epics as the third argument
export function testApiEpic (action$, store, { ajax }) {
return action$.ofType(REQUEST)
.switchMap(action =>
ajax({ url, method })
.map(data => successTestApi(data.response))
.catch(error => failureTestApi(error))
.takeUntil(action$.ofType(CLEAR))
);
}
Alternatively, you could not use the dependencies option of the middleware and instead just use default parameters:
export function testApiEpic (action$, store, ajax = Observable.ajax) {
return action$.ofType(REQUEST)
.switchMap(action =>
ajax({ url, method })
.map(data => successTestApi(data.response))
.catch(error => failureTestApi(error))
.takeUntil(action$.ofType(CLEAR))
);
}
Either one you choose, when we test the epic we can now call it directly and provide our own mock for it. Here are examples for success/error/cancel paths These are untested and might have issues, but should give you the general idea
it('handles success path', (done) => {
const action$ = ActionsObservable.of(requestTestApi())
const store = null; // not used by epic
const dependencies = {
ajax: (url, method) => Observable.of({ url, method })
};
testApiEpic(action$, store, dependencies)
.toArray()
.subscribe(actions => {
expect(actions).to.deep.equal([
successTestApi({ url: '/whatever-it-is', method: 'WHATEVERITIS' })
])
done();
});
});
it('handles error path', (done) => {
const action$ = ActionsObservable.of(requestTestApi())
const store = null; // not used by epic
const dependencies = {
ajax: (url, method) => Observable.throw({ url, method })
};
testApiEpic(action$, store, dependencies)
.toArray()
.subscribe(actions => {
expect(actions).to.deep.equal([
failureTestApi({ url: '/whatever-it-is', method: 'WHATEVERITIS' })
])
done();
});
});
it('supports cancellation', (done) => {
const action$ = ActionsObservable.of(requestTestApi(), clearTestApi())
const store = null; // not used by epic
const dependencies = {
ajax: (url, method) => Observable.of({ url, method }).delay(100)
};
const onNext = chai.spy();
testApiEpic(action$, store, dependencies)
.toArray()
.subscribe({
next: onNext,
complete: () => {
onNext.should.not.have.been.called();
done();
}
});
});
For the first way:
First, use isomorphic-fetch instead of Observable.ajax for nock support, like this
const fetchSomeData = (api: string, params: FetchDataParams) => {
const request = fetch(`${api}?${stringify(params)}`)
.then(res => res.json());
return Observable.from(request);
};
So my epic is:
const fetchDataEpic: Epic<GateAction, ImGateState> = action$ =>
action$
.ofType(FETCH_MODEL)
.mergeMap((action: FetchModel) =>
fetchDynamicData(action.url, action.params)
.map((payload: FetchedData) => fetchModelSucc(payload.data))
.catch(error => Observable.of(
fetchModelFail(error)
)));
Then, you may need an interval to decide when to finish the test.
describe("epics", () => {
let store: MockStore<{}>;
beforeEach(() => {
store = mockStore();
});
afterEach(() => {
nock.cleanAll();
epicMiddleware.replaceEpic(epic);
});
it("fetch data model succ", () => {
const payload = {
code: 0,
data: someData,
header: {},
msg: "ok"
};
const params = {
data1: 100,
data2: "4"
};
const mock = nock("https://test.com")
.get("/test")
.query(params)
.reply(200, payload);
const go = new Promise((resolve) => {
store.dispatch({
type: FETCH_MODEL,
url: "https://test.com/test",
params
});
let interval: number;
interval = window.setInterval(() => {
if (mock.isDone()) {
clearInterval(interval);
resolve(store.getActions());
}
}, 20);
});
return expect(go).resolves.toEqual([
{
type: FETCH_MODEL,
url: "https://test.com/assignment",
params
},
{
type: FETCH_MODEL_SUCC,
data: somData
}
]);
});
});
enjoy it :)
