Testing Facebook Instant Game on local host

I am currently developing an Instant Game. The problem is that while trying to do tests for the Facebook Instant Game platform, I have already exported and uploaded the project 160+ times. It is impossible to keep with that pace, as I want to test leaderboard, bot subscriptions, multiple rounds for each game, final scores etc...

I have read somewhere that we can setup Facebook local host. But I really cant figure out how I can use this in order to run my tests using Facebook local host.

Is it possible to run the tests without having to upload each time the whole project on Facebook Developer platform, by using local host?

Any directions on how I can achieve this, or how I can reduce the whole time of this process?

See the official documentation's section on Testing the game from a local server.

I have already seen the official documentation. What I want to know is, if this helps in any way when testing with Construct 3. Even if I build a local host, will I be able to just run test from Construct easily, or it will take the same time and effort in order to run the test?

You likely will still have to export your project as HTML5 files and place those files in your local server's location.

Why not just try it and compare?

It means you only need to do an export over local files instead of having to upload to Facebook and publish, which should be quicker. Note you should still use the Instant Games export, not the HTML5 export.
