How to Use Selenium for Record and Playback

What Is Selenium IDE?

Selenium IDE is a browser extension that simplifies the process of creating automated tests for web applications. It allows you to record your actions on a website in the browser and playback those actions to verify the expected functionality.

It provides a user-friendly interface that allows you to quickly create and run test cases directly within your browser without requiring any technical expertise.

If you are new to Selenium, we recommend checking this guide on what is Selenium.

What Is Record and Playback in Selenium?

When it comes to codeless test automation, the record and playback feature in Selenium allows you to record your interactions with a website, and then you play them back to see if everything works as expected.

The record and playback feature is available within its ecosystem through the Selenium IDE. When you enable recording, the IDE captures every action you perform in the browser and translates it into a sequence of commands.

These commands are then saved as a test script, which can be executed later to replicate the same interactions. It also eliminates the need for repetitive manual testing and ensures consistency in test execution.

How to Run Selenium IDE Tests on the Cloud?

Up until now, we have learned how to record, playback, and export tests using the Selenium IDE. However, there are limitations to running tests on only your local browser. For instance, if you need to test on several browsers and operating systems to check how your website functions?

This is where cloud testing platforms like TestMu AI come into play. It is an AI-native test execution platform that enables you to execute Selenium IDE tests on a cloud-based grid.

TestMu AI provides you with access to various combinations of browsers and operating systems (Chrome, Firefox, Edge, Safari on Windows/macOS, etc.), which can help you run your tests in parallel, enabling faster software release cycles. Head over to this guide on running Selenium IDE tests on TestMu AI.

Now, let’s see how we can run the Selenium IDE tests on TestMu AI with just a few simple steps.

• Install Node.js.
• Connect Selenium IDE with TestMu AI. For that, you’ll need your Username and Access Key. To get the access, head over to your Account Settings > Password & Security.
• Install the Selenium IDE Runner (or the SIDE Runner) using the below given command:

npm install -g selenium-side-runner

This will help you run the tests outside the browser.

In earlier sections, we already created a test in the Selenium IDE, so let’s just export it.

• Open Selenium IDE and click on the save project icon to save it to your local machine.


This file contains your recorded test case, which will be used to run tests on TestMu AI. You can also access the exported Selenium IDE project in this GitHub repository.

• To direct your tests to the platform, you’ll need the TestMu AI Username and Access Key in the TestMu AI grid URL. In this URL, replace user-name and access-key with your actual TestMu AI credentials.

https://user-name:access-key@hub.lambdatest.com/wd/hub

• Desired capabilities are a set of key-value pairs that let you define the specific environment for test execution.

So, in this step, specify the browsers and operating systems you want to test against. You can also use TestMu AI Automation Capabilities Generator to simplify this process.

For instance, to test on Chrome with Windows 11, we will use the following configuration for Selenium 4:

options = ChromeOptions()
options.browser_version = "latest"
options.platform_name = "Windows 11"

• Open your terminal, navigate to the directory containing your .side file, and run the following command, replacing the user-name and access-key with your actual values:

selenium-side-runner "your-test-file.side" --server 
https://user-name:access-key@hub.lambdatest.com/wd/hub -c " options = 
ChromeOptions() options.browser_version = "latest" options.platform_name = "Windows 11""

Ensure to replace your-test-file.side with the accurate file name of your Selenium IDE project.

With these steps, your Selenium IDE test is now running on the TestMu AI online Selenium Grid.

You can now check the test execution results directly from the TestMu AI Web Automation dashboard.

Best Practices to Use Selenium for Record and Playback

Record and playback is an easy way to automate tests without writing test scripts, but to make the most of this functionality, you’ll need to follow below best practices.

• Avoid using XPath whenever possible. It tends to break when a webpage’s structure changes. Instead, choose more reliable options like IDs, class names, or data attributes.
• Split your tests into smaller, reusable chunks. Instead of cramming multiple actions into a single test, create separate test cases for common tasks like logging in or form submissions.
• Web applications aren’t always static, so use control flow commands like if, while, and times to handle changing conditions. This helps make your tests more adaptable.
• Testing isn’t just about running actions—it’s about verifying results. Add assertions to check that the application behaves as expected at key points in your test.
• Automated tests often fail because they move too fast. Adding wait commands ensures the script pauses until elements are ready, preventing unnecessary failures.
• Recorded scripts aren’t perfect. Instead of relying on them as-is, take the time to refine them, adding logic to handle dynamic content and edge cases.

How Do AI Agents Change Record and Playback Testing in 2026?

AI agents now write a test script directly from a plain English description instead of recording clicks, and they can recover from a locator break that would stop a recorded Selenium IDE script cold.

• Natural language test generation: Tools like GitHub Copilot and Claude Code write a Selenium or Playwright script from a plain English description of the workflow, skipping the record step in this tutorial entirely.
• Self healing selectors: A recorded Selenium IDE script hardcodes the exact CSS or XPath it captured, so it breaks the moment the page changes. An agent can re-locate the same element after a DOM change instead of failing the run, which is why the XPath warning in the best practices above matters even more once AI drives the test.
• Agent driven browsing: A Playwright MCP server or a browser-use session lets an LLM operate a real browser turn by turn from an instruction such as search for an iMac and open the first result, so the recording becomes the agent's own reasoning trace instead of a saved command list.
• A real limitation: none of this removes the review step. An agent generated or agent driven run still needs a person to confirm the assertions match the intended behavior, and a Selenium IDE recording remains the faster choice for a one off regression check like the one in this tutorial.

Conclusion

If you are just getting started with test automation, then there is nothing better than using Selenium IDE to record and playback tests. It lets you record and replay tests, which makes it ideal for accelerating repetitive tasks.

That said, the record and playback feature is not without its limitations. It is good for simple tests and relatively static websites but not ideal for complex workflows or dynamic elements that update often.

You’ve just learned the fundamentals; now let’s get into Selenium IDE and automate some web tests!

Happy testing!
