While trying to set up a basic self-hosted unit testing environment (and CI) that tests this Chainlink VRF random number contract, I am experiencing slight difficulties in how to simulate any relevant blockchains/testnets locally.
For example, I found this repository that tests Chainlinks VRF. However, for default deployment it suggests/requires a free
KOVAN_RPC_URL e.g. from Infura's site and even for "local deployment" it suggests/requires a free
MAINNET_RPC_URL from e.g. Alchemy's site.
I adopted a unit test environment from the waffle framework which is described as:Filestructure ...

to test locally you need to make use of mocks which can simulate having an oracle network. Because you're working locally, a Chainlink node doesn't know about your local blockchain, so you can't actually do proper VRF requests. Note you can try deploy a local Chainlink node and a local blockchain and have them talk, but it isn't fully supported yet so you may get mixed results. Anyway, as per the hardhat starter kit that you linked, you can set the defaultNetwork to be 'hardhat' in the hardhat.config.js file, then when you deploy and run the integration tests (yarn test-integration), it will use mocks to mock up the VRF node, and to test the requesting of a random number. See the test here, and the mock contracts and linktoken get deployed here

After much searching and head scratching as to why
btoa/atob are available in node but NOT available in jest running in node, I finally figured it out. Jest runs all tests inside a
vm, which is an isolated sandbox environment. The
btoa/atob methods are not exposed on the
global object inside of a VM. Best explained by example:

I just solve this issue by correcting the RxJS version to

I have deployed a ERC-1155 based contract (based on OpenZeppelin) and minted some NFTs on this contract successfully. But when I want to use these NFTs in OpenSea, it always says "Unidentified contract".
Following their official Tutorial repository (which does not compile any more because of outdated dependencies and other issues) I have added some (maybe) opensea-specific functions and data that might required for OpenSea in order to work properly. However, OpenSea is able to grab all required data to display an NFT, but as long as they say "Unidentified contract", this all makes no sense so far.
My question has:
has someone already managed to deploy a ERC-1155 and used it with OpenSea properly without this issue? Is there anything we have to "register" somehow contracts that are not based on ERC-721?🔢 Code to reproduce ...

I finally found the root cause! OpenSea expects a public property called
name in order to display the proper Name of the Collection instead of a static label Unidentified contract.
I came across this while looking at their reference code (which depends on a now 3-year-old MultiToken-Contract implementation and needs all in all some downgrades of Node and other tools in order to get it build [a downgrade to Node 10 worked best for me today] ).
I tried following the information here, editing it to match my needs, but so far it's not working. I'm trying to hide a parent div with two child elements. The parent div is part of a list, all with the same classes, and each div has two child elements: an input, and an image. Each input has a unique "data-wapf-label" that I'm trying to select so that I can hide the parent div. The HTML is as follows:...

I am trying to setup a Firebase Cloud Functions repo to run mocha test. However, it throws the following error when I use
import * as firebase from "firebase-functions-test"; or
const firebase = require("firebase-functions-test")();. You can see in my code that I haven't even called the actual firebase functions yet so I think this a setup issue.

What you're exporting and what you're doing with the import don't match. The problem is (probably) the export. What you have is this:
