If you want to test a contract that depends on other contract, but you don't own the latter contract (or you do but you want to test the first contract in isolation), you need to either stub or mock that dependency.

If you are not sure about the difference between a stub and a mock, check this StackOverflow question

Stubbing

If the contract you are testing receives its dependency in some way, you can write a stub contract and use that in your tests. It would be something like this:

contract ContractToTest {

A (Mostly) Complete Guide to React Rendering Behavior

Bài viết cung cấp chi tiết về cách mà React render hoạt động, và việc sử dụng Context và Redux ảnh hưởng thế nào tới quá trình render của React.

"Render" là gì

Rendering is the process of React asking your components to describe what they want their section of the UI to look like, now, based on the current combination of props and state.

	### Exercises for the viewer

	- Phase interrupt handling.
	- Use Swift concurrency.
	- Color scheme awareness.
	- Rework animations to be more spring-like à la what shipped in `0.90.0`.

	RUN THE SCRIPT BY YOURSELF:
	- Run `node paddle-revenue.js` on your server and let it run 24/7.
	- Access the API at http://your_server_ip:8175/ (JSON)

	HOSTED VERSION:
	If you don't want to run the script by your own, you can use the
	hosted version. The price is $5 per month per Paddle account.

	Here is how:

	// Based on Kickstarter-Prelude version
	// https://github.com/kickstarter/Kickstarter-Prelude/blob/master/Prelude-UIKit/UIImage.swift
	extension UIImage {

	/**
	- parameter color: A color.
	- returns: A 1x1 UIImage of a solid color.
	*/
	static func pixel(ofColor color: UIColor) -> UIImage {
	let lightModeImage = UIImage.generatePixel(ofColor: color, userInterfaceStyle: .light)

	// Original article here: https://www.fivestars.blog/code/redacted-custom-effects.html

	import SwiftUI

	// MARK: Step 1: Create RedactionReason

	public enum RedactionReason {

	case placeholder
	case confidential

	struct ContentView: View {
	var body: some View {

	VStack{

	Label("Hello Label", systemImage: "sun.min")
	.font(.system(.title, design: .rounded))

	Label("Title only label", systemImage: "sun.min")
	.font(.system(.title, design: .rounded))
