PhantomJS vs Selenium: What are the differences?

Key Differences between PhantomJS and Selenium

PhantomJS and Selenium are both popular tools used for web testing and automation. While they serve similar purposes, there are some key differences between the two.

  1. Execution Environment: PhantomJS is a headless browser that can execute JavaScript in an environment without a graphical user interface, making it suitable for server-side testing. On the other hand, Selenium requires a graphical user interface to execute tests and interact with web elements.

  2. Language Support: PhantomJS is primarily based on JavaScript and supports only JavaScript for writing test scripts. Selenium, on the other hand, supports multiple languages such as Java, C#, Ruby, Python, and more, providing developers with a wider range of options.

  3. Browser Compatibility: Selenium can automate testing across multiple web browsers including Chrome, Firefox, Safari, and Internet Explorer. PhantomJS, being a headless browser, does not have the same compatibility and is limited to simulating a specific rendering engine.

  4. Development and Maintenance: Selenium is an open-source project with a large community of contributors, making it well-documented and continuously maintained. PhantomJS, although it was widely used in the past, is no longer actively maintained and has been deprecated in favor of other tools.

  5. Execution Speed: PhantomJS is known for its fast execution speed as it does not require rendering and displaying web pages. This makes it suitable for tasks that require fast processing, such as web scraping. In comparison, Selenium may have a slower execution speed due to its need to interact with actual browser instances.

  6. Visual Testing: Selenium provides better support for visual testing as it can interact with real browser instances and capture screenshots or compare images for visual regression testing. PhantomJS, being headless, does not have the same capabilities for visual testing.

In summary, PhantomJS is a headless browser with fast execution speed, limited browser compatibility, and primarily supports JavaScript. Selenium, on the other hand, supports multiple languages, has better browser compatibility, supports visual testing, and is continuously maintained by a large community.

I am using Node 12 for server scripting and have a function to generate PDF and send it to a browser. Currently, we are using PhantomJS to generate a PDF. Some web post shows that we can achieve PDF generation using Puppeteer. I was a bit confused. Should we move to puppeteerJS? Which one is better with NodeJS for generating PDF?

You better go with puppeteer. It is basically chrome automation tool, written in nodejs. So what you get is PDF, generated by chrome itself. I guess there is hardly better PDF generation tool for the web. Phantomjs is already more or less outdated as technology. It uses some old webkit port that's quite behind in terms of standards and features. It can be replaced with puppeteer for every single task.

I suggest puppeteer to go for. It is simple and easy to set up. Only limitaiton is it can be used only for chrome browser and currently they are looking into expanding into FF. The next thing is Playwright which is just a scale up of Puppeteer. It supports cross browsers.

    What is PhantomJS?

    PhantomJS is a headless WebKit scriptable with JavaScript. It is used by hundreds of developers and dozens of organizations for web-related development workflow.

    What is Selenium?

    Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.

    What are some alternatives to PhantomJS and Selenium?
    Electron
    With Electron, creating a desktop application for your company or idea is easy. Initially developed for GitHub's Atom editor, Electron has since been used to create applications by companies like Microsoft, Facebook, Slack, and Docker. The Electron framework lets you write cross-platform desktop applications using JavaScript, HTML and CSS. It is based on io.js and Chromium and is used in the Atom editor.
    Protractor
    Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
    wkhtmltopdf
    wkhtmltopdf and wkhtmltoimage are command line tools to render HTML into PDF and various image formats using the QT Webkit rendering engine. These run entirely "headless" and do not require a display or display service.
    SlimerJS
    It allows you to manipulate a web page with an external Javascript script: opening a webpage, clicking on links, modifying the content... It is useful to do functional tests, page automation, network monitoring, screen capture etc.
    Puppeteer
    Puppeteer is a Node library which provides a high-level API to control headless Chrome over the DevTools Protocol. It can also be configured to use full (non-headless) Chrome.
