Automated testing Tailwind CSS Websites

The Tailwind CSS framework provides an easy way to create consistent and beautiful websites. In combination with the power of Selenium, you can perform UI testing on a Tailwind powered website, on multiple browsers, versions and operating systems.

To get started, install and set up Selenium through the Selenium Project Page. Once installed, you can write your first Selenium test script to open a browser, navigate to a Tailwind powered website and perform various actions and assertions.

For an example of a Selenium test script, please see the example below. We will navigate to the Tailwind CSS homepage, find an element by using a Tailwind CSS locator and click it.

const { Builder, By, Key, until } = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');

(async function example() {
  const options = new chrome.Options();

  // Launch Chrome browser

  const driver = await new Builder()
    .forBrowser('chrome')
    .setChromeOptions(options)
    .build();

  try {
    // Navigate to Tailwind CSS website homepage

    await driver.get('https://tailwindcss.com/');

    // Perform interactions and assertions (replace these with your actual tests)

    await driver.findElement(By.linkText('Documentation')).click();
    await driver.wait(until.urlContains('/docs'), 5000); // Wait for the documentation page to load

    const pageTitle = await driver.getTitle();
    console.log('Page Title:', pageTitle);

    // You can add more interactions and assertions here based on your testing requirements.


  } catch (error) {
    console.error('Test failed:', error);
  } finally {
    // Quit the browser after the test is done (whether it passes or fails)

    await driver.quit();
  }
})();

Automated testing in combination with Tailwind CSS follows similar principles as automated testing with any other CSS framework. The main focus is to ensure that the application functions correctly and appears as expected, regardless of the underlying CSS framework.

In your test cases, utilize Tailwind CSS classes to apply different styles or trigger specific states of elements. For example, you can use classes like .bg-red-500, .text-blue-700, or .hover:bg-green-300 to test different styles and states.

Tailwind CSS utility classes make it easy to apply specific styles directly to elements. Use these utility classes in your test cases to ensure that the correct styles are being applied.

Visually testing Tailwind CSS pages on multiple browsers with the help of Selenium is important to ensure a seamless and consistent user experience across different platforms and mobile devices. Tailwind is a popular utility-first CSS framework and allows developers to rapidly build responsive and aesthetically appealing web pages. However, with various browsers and various operating systems, there is a possibility of CSS rendering problems that might affect the visual integrity of the webpage.

By using Selenium for visual testing, developers can automatically capture and compare screenshots of Tailwind CSS pages across multiple browsers. This helps in identifying any unintended cumulative layout shifts (CLS), misaligned elements or inconsistent styles that might occur due to browser-specific quirks. Detecting such discrepancies early on in the process ensures prompt resolution.

TestingBot provides Screenshot Testing in the cloud, which allows you to test your webpages on over 4000 different browser combations.
