Create Helpers

We recommend that you follow the page model pattern to extract reusable test code. This pattern allows you to abstract out both page structure and test logic.

If you need to extract only the helper functions, however, you can export them from a separate script file.

The following example shows a helper.js file that exports the enterName, typeComment, and submitForm asynchronous functions:

import { t } from 'testcafe';

export async function enterName(name) {
    await t.typeText('#developer-name', name);

export async function typeComment(text) {
    await t
        .typeText('#comments', text);

export async function submitForm() {

Note that this file imports t (the test controller) from the testcafe module. You don't need to pass t to helper functions because TestCafe can resolve the current test context and provide the correct test controller instance.

In test code, import functions from helper.js and call them with the await keyword:

import { Selector } from 'testcafe';
import { enterName, typeComment, submitForm } from './helper.js';

fixture `My Fixture`
    .page ``;

test('My Test', async t => {
    const name = 'John Heart';

    await enterName(name);
    await typeComment('Here is what I think...');
    await submitForm();
    await t.expect(Selector('#article-header').textContent).contains(name);
