[Lesson 9] Mocha staging test timeout, What can we do with pending VRF fulfillments ?

[whitefusion]

I also meet the mocha staging test timeout problem like
Error: Timeout of 300000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/Users/whitefusion/Dev/hardhat-lottery/test/staging/Raffle.staging.test.ts)

Then I check my Raffle Etherscan, both RaffleEnter and RequestedRaffleRaffleWinner are emitted as expected.

Then I check my Upkeeper Subscription which executes every minute ( to speed up my test) , it also works.

Then I go to my VRF Subscription

There is a big pending here for 10+ minutes, and it cannot be accelerated or be canceled.

So what can we do here?

The pending ends after I fund 1LINK ............. 😤
Does the funding push the pending to end ???
And the staging test passed 🥹

Waiting for a better solution instead of manually charging VRF everytime I run this staging test

@whitefusion It stops at the pending state due to the shortage of funds (this is the reason when you funded the subscription it went further). There are two types Subscription based VRF and Direct Funding VRF, subscription based is recommended because, with the main dashboard, you can monitor your many smart contracts and can funds to all, on the other hand, direct funding methods are connected to only a single smart contract where you fund your VRF inside contract.

You must checkout the Chainlink VRF docs for further differences and then you can choose which one you need.

Thank u for your reply.
But No.
A single fulfillment only cost ~0.3LINK. I have ~1.27 LINK at that time.
And the pending happens even I have 6+ LINK left in the balance.
