  • Collecting JavaScript code coverage with Capybara in Ruby on Rails application
    6 projects | dev.to | 14 May 2024
    At the next stage, they are merged into one JSON file. For this purpose, we use nyc (Istanbul’s command line interface).
  • Migrating from Jest to Vitest for your React Application
    16 projects | dev.to | 14 Dec 2023
    Native code coverage via v8 or istanbul.
  • Testing Vue components the right way
    2 projects | dev.to | 6 Feb 2023
    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:
  • Don't target 100% coverage
    3 projects | dev.to | 19 Jan 2023
    Here is a quote from istanbul, one of the most used code coverage tool:
  • Unit testing like a Hacker
    6 projects | dev.to | 28 Oct 2022
    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.
  • Auto-Publish Your Test Coverage Report on GitHub Pages
    2 projects | dev.to | 28 Oct 2022
    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.
  • Dear Linux, Privileged Ports Must Die
    2 projects | news.ycombinator.com | 31 Aug 2022
    > 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.

  • Comprehensive coverage Jest+Playwright in Next.js TS
    7 projects | dev.to | 29 Jun 2022
    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
  • When developing in React, what do you find most frustrating or cumbersome?
    3 projects | /r/reactjs | 14 Mar 2022
    https://istanbul.js.org/ measures how much of your code is covered by tests
  • Production Ready React
    3 projects | dev.to | 18 Jan 2022
    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.

What are some alternatives?

When comparing jest and nyc you can also consider the following projects:

tap - Test Anything Protocol tools for node

istanbul - Yet another JS code coverage tool that computes statement, line, function and branch coverage with module loader hooks to transparently add coverage when running tests. Supports all JS coverage use cases including unit tests, server side functional tests and browser tests. Built for scale.

vitest - Next generation testing framework powered by Vite.

Cucumber.js - Cucumber for JavaScript

playwright-test-coverage - Extends Playwright test to measure code coverage

Sinon.JS - Test spies, stubs and mocks for JavaScript.

mocha - ☕️ simple, flexible, fun javascript test framework for node.js & the browser

WebdriverIO - Next-gen browser and mobile automation test framework for Node.js

jasmine - Simple JavaScript testing framework for browsers and node.js

ava - Node.js test runner that lets you develop with confidence 🚀

SonarQube - Continuous Inspection
