There are plans to support generators on the steps?

[srhwork]

Hi.

I recently started using "cucumber" and I love it. I'm using "WebdriverIO" in my tests and I would like to use generators. Like this:

this.Then(/^I should see "(.*)" as the page title$/, function*(title, next) {

        let result = yield this.driver
             .url( "http://localhost:3000" )
             .title();

        expect( result ).to.equal( title );
        next(); 
 });

So, there are plans to support generators on the steps?

Thanks.

Looking at the idea behind for es6 generators, I believe support for generators is simply based on what version of node you are running. What happens when you run the given code? (I'm curious what would happen if you were to remove next as well)

Ok, if I run something like this:

this.Then(/^I should see "(.*)" as the page title$/, function*(title) {

        let result = yield driver
            .execute(() => {
                return document.title;
            });

        console.log(result);

        yield driver
            .end();
});

The steps pass without open the browser. The scenario is successful but does nothing, even the result variable never print.

And if I run something like this:

this.Then(/^I should see "(.*)" as the page title$/, function*(title, next) {

        let result = yield driver
            .execute(() => {
                return document.title;
            });

        console.log(result);

        yield driver
            .end();

        next();
});

The step exceed the timed out with any time I set.

I use Node v4.2.1 with generators support.

So, I think "cucumber" does not support the flow generator. How to make do it exceeds my knowledge.

Thanks.

Looks like we can use is-generator to check if the function supplied is a generator function and then use co to run it.

I like the idea of supporting it. Personally don't have time to work on this at the moment and probably won't until we get to 1.0. Pull request welcome.
