call

You can use call to execute any async action within your test spec. It accepts promises and stops the execution until the promise has been resolved.

info

With WebdriverIO deprecating synchronous usage (see RFC) this command is not very useful anymore.

Usage

browser.call(callback)

Parameters

Name	Type	Details
callback	Function	function to be called

Example

call.js

it('some testing here', async () => {
    await browser.url('http://google.com')
    // make an asynchronous call using any 3rd party library supporting promises
    // e.g. call to backend or db to inject fixture data
    await browser.call(() => {
        return somePromiseLibrary.someMethod().then(() => {
            // ...
        })
    })

    // example for async call to 3rd party library that doesn't support promises
    const result = await browser.call(() => {
        return new Promise((resolve, reject) => {
            someOtherNodeLibrary.someMethod(param1, (err, res) => {
                if (err) {
                    return reject(err)
                }
                resolve(res)
            })
        })
    })
});
