[🐛 Bug]: Different behaviour of handling getText() inside of call back function for v8 and v7.27/v7.26 #9388

Closed 7artur7 closed 1 year ago

7artur7 commented 1 year ago

Have you read the Contributing Guidelines on issues?

WebdriverIO Version

8.0.9

Node.js Version

18.12.1 (OS X 12.5)

Mode

WDIO Testrunner

Which capabilities are you using?

capabilities: [{
        maxInstances: 1,
        browserName: 'chrome',
    }],

What happened?

After update to v8.0.9, I faced unexpected behaviour while using getText() inside of callback functions of e.g. find(), map() methods. Method isn't executed or registered as pending promise.

Example:

const contributeLink = await $$('a.navbar__item.navbar__link').find(async function(link) {
            const text = await link.getText()
            return text === 'Contribute'})

Wouldn't click on Contribute but stay on Docs. If debug this code execution is jumped out on first call to const text = await link.getText()

Or 

get tagsListItems () { return this.$$tagsListItems.map($tag => $tag.getText()); }

Would return set of pending promises for each $tag.getText().

In wdio 7.27.0. Both methods works correctly. Contribute tab is clicked. Tag text being returned.

What is your expected behavior?

getText() and other element async methods work the same as in v7 or it is documented that v8 behaviour is a correct one.

How to reproduce the bug.

Dependencies are

  "dependencies": {
    "@wdio/cli": "^8.0.9",
    "chromedriver": "^108.0.0",
    "wdio-chromedriver-service": "^8.0.1"
  },
  "devDependencies": {
    "@wdio/local-runner": "^8.0.9",
    "@wdio/mocha-framework": "^8.0.9",
    "@wdio/selenium-standalone-service": "^8.0.9",
    "@wdio/spec-reporter": "8.0.8"
  }
}

Run next simple test in Wdio testrunner

describe('webdriver.io page', () => {
    it('click on Contribute', async function() {
        await browser.url('https://webdriver.io');
        const contributeLink = await $$('a.navbar__item.navbar__link').find(async function(link) {
            const text = await link.getText()
            return text === 'Contribute'})
        await contributeLink.click();
        await expect(browser).toHaveTitle(
          'Contribute | WebdriverIO'
        )
    });
});

Is there an existing issue for this?

Thanks for reporting!

I can reproduce this problem and it seems that the package we use to make array operation async/await aware is not working anymore. The file to look at first would be packages/wdio-utils/src/shim.ts.

Any contributions that resolves the bug are highly appreciated. Please take a look into our contribution guidelines and let us know if you have any questions. Cheers!
