I have followed the instructions for configurating WebDriverIO (and Mocha) for a TypeScript. Specifically to: install tsx;

$ npm install tsx --save-dev

and include the following in tsconfig.ts;

{
    "compilerOptions": {
        "types": [
            "node",
            "@wdio/globals/types",
            "@wdio/mocha-framework",
        ]
    }
}

And yet the follwing:

import { browser } from '@wdio/globals'

describe('Electron', () => {
    it('Should print title', async () => {
        const title = await browser.getTitle()
    })
})

produces this error:

Property 'getTitle' does not exist on type 'Browser'.ts(2339)
any

As the compile understands browser to be:

interface Browser {}
