Diseñando Pruebas Efectivas con la Biblioteca de Pruebas de React

Rate this content
Bookmark

La Biblioteca de Pruebas de React es un gran marco para las pruebas de componentes de React porque responde muchas preguntas por ti, por lo que no necesitas preocuparte por esas preguntas. Pero eso no significa que las pruebas sean fáciles. Todavía hay muchas preguntas que tienes que resolver por ti mismo: ¿Cuántas pruebas de componentes debes escribir vs pruebas de extremo a extremo o pruebas de unidad de nivel inferior? ¿Cómo puedes probar una cierta línea de código que es difícil de probar? ¿Y qué se supone que debes hacer con esa persistente advertencia de act()?


En esta masterclass de tres horas, presentaremos la Biblioteca de Pruebas de React junto con un modelo mental de cómo pensar en el diseño de tus pruebas de componentes. Este modelo mental te ayudará a ver cómo probar cada bit de lógica, si debes o no simular dependencias, y ayudará a mejorar el diseño de tus componentes. Te irás con las herramientas, técnicas y principios que necesitas para implementar pruebas de componentes de bajo costo y alto valor.


Tabla de contenidos

- Los diferentes tipos de pruebas de aplicaciones de React, y dónde encajan las pruebas de componentes

- Un modelo mental para pensar en las entradas y salidas de los componentes que pruebas

- Opciones para seleccionar elementos DOM para verificar e interactuar con ellos

- El valor de los mocks y por qué no deben evitarse

- Los desafíos con la asincronía en las pruebas de RTL y cómo manejarlos


Requisitos previos

- Familiaridad con la construcción de aplicaciones con React

- Experiencia básica escribiendo pruebas automatizadas con Jest u otro marco de pruebas unitarias

- No necesitas ninguna experiencia con la Biblioteca de Pruebas de React

- Configuración de la máquina: Node LTS, Yarn

Ivan’s first attempts at performance debugging were chaotic. He would see a slow interaction, try a random optimization, see that it didn't help, and keep trying other optimizations until he found the right one (or gave up).
Back then, Ivan didn’t know how to use performance devtools well. He would do a recording in Chrome DevTools or React Profiler, poke around it, try clicking random things, and then close it in frustration a few minutes later. Now, Ivan knows exactly where and what to look for. And in this workshop, Ivan will teach you that too.
Here’s how this is going to work. We’ll take a slow app → debug it (using tools like Chrome DevTools, React Profiler, and why-did-you-render) → pinpoint the bottleneck → and then repeat, several times more. We won’t talk about the solutions (in 90% of the cases, it’s just the ol’ regular useMemo() or memo()). But we’ll talk about everything that comes before – and learn how to analyze any React performance problem, step by step.
(Note: This workshop is best suited for engineers who are already familiar with how useMemo() and memo() work – but want to get better at using the performance tools around React. Also, we’ll be covering interaction performance, not load speed, so you won’t hear a word about Lighthouse 🤐)

With the release of React 18 we finally get the long awaited concurrent rendering. But how is that going to affect your application? What are the benefits of concurrent rendering in React? What do you need to do to switch to concurrent rendering when you upgrade to React 18? And what if you don’t want or can’t use concurrent rendering yet?

There are some behavior changes you need to be aware of! In this workshop we will cover all of those subjects and more.

Join me with your laptop in this interactive workshop. You will see how easy it is to switch to concurrent rendering in your React application. You will learn all about concurrent rendering, SuspenseList, the startTransition API and more.

The addition of the hooks API to React was quite a major change. Before hooks most components had to be class based. Now, with hooks, these are often much simpler functional components. Hooks can be really simple to use. Almost deceptively simple. Because there are still plenty of ways you can mess up with hooks. And it often turns out there are many ways where you can improve your components a better understanding of how each React hook can be used.You will learn all about the pros and cons of the various hooks. You will learn when to use useState() versus useReducer(). We will look at using useContext() efficiently. You will see when to use useLayoutEffect() and when useEffect() is better.

ReactJS is wildly popular and thus wildly supported. TypeScript is increasingly popular, and thus increasingly supported.

The two together? Not as much. Given that they both change quickly, it's hard to find accurate learning materials.

React+TypeScript, with JetBrains IDEs? That three-part combination is the topic of this series. We'll show a little about a lot. Meaning, the key steps to getting productive, in the IDE, for React projects using TypeScript. Along the way we'll show test-driven development and emphasize tips-and-tricks in the IDE.

In this workshop, you'll learn how to build your first full stack dapp on the Ethereum blockchain, reading and writing data to the network, and connecting a front end application to the contract you've deployed. By the end of the workshop, you'll understand how to set up a full stack development environment, run a local node, and interact with any smart contract using React, HardHat, and Ethers.js.

Are you a React developer trying to get the most benefits from TypeScript? Then this is the workshop for you.In this interactive workshop, we will start at the basics and examine the pros and cons of different ways you can declare React components using TypeScript. After that we will move to more advanced concepts where we will go beyond the strict setting of TypeScript. You will learn when to use types like any, unknown and never. We will explore the use of type predicates, guards and exhaustive checking. You will learn about the built-in mapped types as well as how to create your own new type map utilities. And we will start programming in the TypeScript type system using conditional types and type inferring.

A Guide to React Rendering Behavior
Top Content
React is a library for "rendering" UI from components, but many users find themselves confused about how React rendering actually works. What do terms like "rendering", "reconciliation", "Fibers", and "committing" actually mean? When do renders happen? How does Context affect rendering, and how do libraries like Redux cause updates? In this talk, we'll clear up the confusion and provide a solid foundation for understanding when, why, and how React renders. We'll look at: - What "rendering" actually is - How React queues renders and the standard rendering behavior - How keys and component types are used in rendering - Techniques for optimizing render performance - How context usage affects rendering behavior| - How external libraries tie into React rendering

Humans are natural problem solvers and we're good enough at it that we've survived over the centuries and become the dominant species of the planet. Because we're so good at it, we sometimes become problem seekers too–looking for problems we can solve. Those who most successfully accomplish their goals are the problem eliminators. Let's talk about the distinction between solving and eliminating problems with examples from inside and outside the coding world.

Can useEffect affect your codebase negatively? From fetching data to fighting with imperative APIs, side effects are one of the biggest sources of frustration in web app development. And let’s be honest, putting everything in useEffect hooks doesn’t help much. In this talk, we'll demystify the useEffect hook and get a better understanding of when (and when not) to use it, as well as discover how declarative effects can make effect management more maintainable in even the most complex React apps.
