Bug

What is the current behavior?

Unable to run tests. After upgrading to v0.17.2 and running:

testcafe chrome test1.js --no-sandbox

I get the following error:

(node:19069) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Cannot find module 'testcafe-hammerhead'

(node:19069) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the No de.js process with a non-zero exit code.

What is the expected behavior?

Tests should run successfully.

How would you reproduce the current behavior (if this is a bug)?

Run tests.

Provide the test code and the tested page URL (if applicable)

Tested page URL: Tested on localhost.

Test code

import { Selector, Role, ClientFunction } from 'testcafe';

const messengerBody = Selector('div').withAttribute('data-test', 'container');

const user = Role('http://localhost:8091', async t => {
    await t
        .typeText('#user', 'someid')
        .typeText('#pass', 'someuserpass')
        .click('#btn');

});

fixture `Login`
    .page('http://localhost:8091');


test('check if feature is loaded', async t => {
    await t
        .useRole(user)
        .expect(messengerBody.exists).ok();
});

Hi @planet71,

Have you installed testcafe locally into your project or globally (with the -g npm flag)? If locally could you please try to remote the node_modules directory and reinstall all dependencies again?

Hi @AlexanderMoskovkin,
I've removed node_modules and reintsalled all dependencies, but it didn't help out.

[AlexanderMoskovkin]

what do you use, npm or yarn?

Hello @planet71, I've encountered similar type of issue, but not with version 0.17.2. If you are using npm, try to clean cache npm cache clean -f, remove node_modules and install TestCafe. If it won't help, try to install [email protected].

Cleaning cache helped out. Thanks.
