Cypress and Excel Test Data - cypress

Question

Has anyone used excel to store test data while runing cypress tests? I am trying to make this work, but since I cant access the file system with browserify I cant read excel test data file. Anyone got this working? DO you have any links/code on how to get it working?
Thanks.

Answer 1

I realised that normal excel processing packages wont work with cypress and typescript, since u r using browserfiy. browserify will prevent you from performing file read/write operations.
as a workaround, i only read the excel file prior to browserifying it (in the plugins/index.js), and convert it into a json file and save it in the fixtures folder.
then in the support/index.js in a beforeAll hook i read the json file as a fixture and save it to an aliased variable. Now I can parse data from the aliased variable and use it where required in cypress context throughout the test. this is what worked for me.

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 convert 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");
});
});
});
});
