Error: describe expects a function argument; received [object AsyncFunction]

[Ish Abbi]

Hi,

I'm trying to run my tests against a data set which is defined as a json. The approach works when I try to use it for the it method. But when I try to do the same for the describe method I get the below exception :

[chrome #11] *(node:10701) UnhandledPromiseRejectionWarning: Error: describe expects a function argument; received [object AsyncFunction]

Below is the code snippet :

homePageDataProvider.forEach(async (culture) => {

   await describe('Test Suite ' + culture.locale + ' Culture', async () => {

       beforeEach(async () =>  {

           await homePageActions.goToUrl(culture.locale);

           await homePageActions.selectCulture(culture.locale);

       });

        culture.universalHeader.forEach((obj) => {

           it('Validate header option : ' + obj.text, async () => {

               await homePageActions.clickHeaderOption(obj);

           })

       });

   });

});

Anything that can be done?

Thanks,

Ish

The `describe` function in Jasmine does not support asynchronous callbacks (in any form). It doesn't look like you're actually using `await` in that function though, so you might be able to just remove the `async` keyword in your call to describe.

Hope this helps. Thanks for using Jasmine!
