About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

CodeceptJS is an end-to-end testing framework that presents Playwright, WebDriver, Puppeteer, Appium, and other automation engines through common `I` steps. BDD-style scenarios keep actions and assertions linear and readable.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Express E2E behavior with high-level `I` steps

Steps such as I.amOnPage, I.click, and I.see turn browser behavior and assertions into readable scenarios.

Choose Playwright, WebDriver, Appium, and other Helpers

Automation engines are supplied through Helpers, allowing web and mobile projects to share the same scenario style.

Sources: [2][3]

For teams standardizing E2E test language across applications

It fits teams that want to hide low-level automation APIs behind shared scenarios, page objects, and reusable steps.

Treat 4.x as an evolving line and pin Helper compatibility

The default-branch package is 4.0.0-rc.1 with Node.js 22.12+. Pin the intended release and verify browser-engine compatibility before adopting it broadly.

Supplemental curator note

The default branch is 4.x; its package is currently 4.0.0-rc.1 and requires Node.js 22.12.0+. The README also references 4.2 requirements, so this is an actively evolving line. Choose and pin the Helper engine and browser dependencies used by the project.

Try it in 3 steps

  1. 1

    Install and initialize CodeceptJS

    Follow the 4.x README and choose the Helper engine while generating the test environment.

    npm i codeceptjs --save && npx codeceptjs init
  2. 2

    Generate the first test

    Create a test file ready for a BDD-style Scenario.

    npx codeceptjs generate:test
  3. 3

    Run with visible steps

    Execute the E2E scenario while printing the user-perspective I steps.

    npx codeceptjs run --steps
