tape VS nyc

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.

Native code coverage via v8 or istanbul.

Writing tests is essential, and knowing whether you test all the required cases for your logic is even more critical. The most common testing coverage tool is Istanbul, where you can see how well your tests exercise your code by lines, functions, and branches. Below is an example of how the test coverage report looks in your terminal:

Here is a quote from istanbul, one of the most used code coverage tool:

Unit testing framework was already implemented, using Vitest so I started hacking by setting up a coverage provider to explicitly identify the covered/uncovered lines and mentioned this to the maintainer in the comments. I used Istanbul 🇹🇷 for this purpose.

Your project probably has a coverage report. If you’re using Jest as your unit test runner, generating a coverage report is embedded in it. It is done with Istanbul under the hood, which generates a nice HTML page presenting the entire project unit test coverage.

> This is a rant written by someone with just enough understanding to be dangerous, but not quite enough wisdom to know why things are still the way they are. Most of the complaints raised are subtly inaccurate.

Author seems aware of CAP_NET_BIND_SERVICE: https://source.small-tech.org/site.js/app/-/issues/169 and https://github.com/istanbuljs/nyc/issues/1281 – the "side effects" are NodeJS explicitly checking for it, so that's a NodeJS thing and not a Linux thing.

Yet curiously it's completely unmentioned in this article, in spite that this is probably what started the author's dislike of privileged ports. I guess it was inconvenient as it got in the way of angrily ranting.

This approach will create two json coverage files, which will be merged together by NYC. Therefore the results will be purely local. If You don't mind using online tools like Codecov or Coveralls for merging data from different tests, then go ahead and use them. They will probably also be more accurate. But if You still want to learn how to get coverage from E2E, then please read through

https://istanbul.js.org/ measures how much of your code is covered by tests

Jest uses a package called Istanbul to provide test coverage metrics such as statement, branch, function, and line coverage so that you can understand and enforce the quality of your test suite, providing more confidence in releases.

So let’s see if nyc (the code coverage generator) can help with that. Hmm… this documentation seems interesting! So basically what I understand from it is that I need to collect all the reports from the different packages and then run the nyc report over it. The flow should be like this:
