How to extend Element class method in TypeScript using webdriverio? about v4 HOT 6 OPEN

From @mgrybyk on March 12, 2019 16:39

If you talking about webdriverio 5 (5.7.2), then

1. add commands

browser.addCommand("browserLevel", function () { ... })
browser.addCommand("elementLevel", function () { ... }, true)

2. add typings for new commands

declare namespace WebdriverIO {
    interface Browser {
        browserLevel (): void
    }

    interface Element {
        elementLevel (): void
    }
}

NOTE
At this moment there is no way to override commands, there is planned work to do it #3604

from v4.

@mgrybyk We're currently using Webdriver 4.x due to compatibility issues with TypeScript & Cucumber. Is there an equivalent for 4.x?

Edit: just checked the codebase, looks like addCommand exists in 4.x as well.

from v4.

At this point I can't help you, I was using v4 with js.

from v4.

@mgrybyk if people use addCommand can they somehow extend the existing typescript definition with their command?

from v4.

Yes, in v5, as it mentioned here webdriverio/webdriverio#3719 (comment)

from v4.

Ah ok, now I see that @draganrakas is using v4. Moving the issue there then.
