tape VS jest

Last but not least important are ava, uvu and tape; they are a really light and fast test runners.

A more minimalist approach is this tape module and the TAP protocol. https://www.npmjs.com/package/tape

OK will do. Do you have any tips on finding a suitable project? Ideally I was hoping to to contribute to a piece of software that I actually use/know/like/want to improve. Given that, and my area of expertise, I had shortlisted Signal Desktop, and Tape.

Reactjs I have the following components: // Hello.jsexport default (React) => ({name}) => { return ( Hello {name ? name : 'Stranger'}! )}// App.jsimport createHello from './Hello'export default (React) => () => { const Hello = createHello(React) const helloProps = { name: 'Jane' } return ( )}// index.jsimport React from 'react'import { render } from 'react-dom'import createApp from './App'const App = createApp(React)render( , document.getElementById('app')) And I want to set up a test to see if the App component contains one Hello component. I tried the following, using Tape and Enzyme: import createApp from './App'import React from 'react'import test from 'tape'import { shallow } from 'enzyme'test('App component test', (assert) => { const App = createApp(React) const wrapper = shallow() assert.equal(wrapper.find('Hello').length === 1, true)}) But the result was that the length property of the find result was equal to 0, when I was expecting it to be equal to 1. So, how do I find my Hello component? Answer link : https://codehunter.cc/a/reactjs/find-component-by-display-name-when-the-component-is-stateless-functional-with-enzyme

For us at Begin and Architect, tape has been in use for several years. tape has a stable and straightforward API, routine maintenance updates, and outputs TAP, making it really versatile. While TAP is legible, it's not the most human-readable format. Fortunately, several TAP reporters can help display results for developers. Until recently, Begin's TAP reporter of choice was tap-spec. Sadly tap-spec wasn't kept up to date and npm began reporting vulnerabilities.

I really enjoy Ava [1] or anything assert-tape-like [2]. "uvu" [3] is getting a lot of love lately, but it's very feature limited and much of it's touted advantages are at the detriment to feature set.

Jest is great for front-end (or full stack integration) testing, but I feel it's specialized for that use-case and doesn't always play nice with backend/middle-tier testing needs.

Jest

you have selected a testing framework. In my case, it's Jest with Supertest

Jest, created and maintained by Facebook, is a JavaScript testing framework with a focus on simplicity. It is often recognized for its zero-configuration setup and seamless integration, especially with React applications, making it a favored choice for developers in both small-scale projects and large enterprise applications.

Jest (https://jestjs.io/)

console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation

Note: I will be using Jest as testing framework throughout the examples.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.

Jest is a well-regarded JavaScript testing framework primarily designed for React applications, although its utility extends to projects using Babel, JavaScript, Node, Angular, and Vue. Created by Facebook, Jest emphasizes ensuring the correctness of JavaScript codebases. It allows developers to write tests with a familiar, feature-rich API, making the testing process swift and enjoyable​​.
