tape VS Sinon.JS

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.

If you are using a mocking library, such as sinon, jest-mock, or ts-mockito, make sure that it is compatible with Jest. You may need to install additional packages or configure them in your configuration file. For example, to use sinon with Jest, you can install the sinon-jest package and add the following to your configuration file:

Mocha is a test runner, Chai is an assertion library, Sinon is a mocking library, this normally the combination you would need to use if you choose mocha, but there are others.

Instead, use pure functions + dependency inject your stubs (e.g. parameter to function). Also note, no need for Sinon or some other test double library. JavaScript is so good nowadays to easily make objects/classes/functions or any combination thereof on the fly that are terse.

I've had some good experiences with Ava + Sinon. I've personally disliked Jest because it seemed to do some weird trickery in the background that prevented me from using ES modules.

🤖 You can use the Mocha testing framework with the Chai assertion library to write tests for your Express controller. You can also use the Sinon library to mock the database calls. This will allow you to test the controller without actually making a call to the database. You can also use the SuperTest library to make HTTP requests to the controller and test the response.

You can use sinon js to create a mock version of your http library (axios) that responds with the data you’re expecting.

Assertions are the checkpoints of our test block that confirm if an automated test has passed or failed. Cypress bundles the Chai, jQuery, and Sinon.JS libraries for assertions. They check the desired, expected application in which the test is running. A complete listing of assertions can be found in the documentation here.

ES module is basically a "class" that you inject dependencies into through imports. And for tests you just use something like sinon to swap module dependencies for mocks.

You can use a tool like sinon to pass in your own function instead of the real moment library. From there you can write tests that ensure moment was invoked appropriately.

Let's configure tests with mocha, chai and sinon on Typescript in a few steps.
