## Introduction

You can use Endtest to test Chrome Extensions.

## Steps

1. Your **Chrome Extension** must be in a **ZIP** file.  
2. Upload that **ZIP** file in our [Drive](https://app.endtest.io/drive) section.  
3. Copy the **File Download URL** for the uploaded **ZIP** file.  
4. Go to the **Advanced Settings** section for your test suite.  
5. Paste the **File Download URL** in the **Add Chrome Extension** input.  
6. Click on the **Save** button.  
7. Execute the test suite in **Chrome**.

The **Chrome Extension** will be automatically loaded in the **Chrome** browser once the test execution starts.

To access certain sections from the **Chrome Extension**, you might need to get the **ID** of that extension.

The **ID** will be unique for each test execution.

You can use an `Execute JavaScript` step to extract the **ID** from the URL for that **Chrome Extension** and store it inside a JavaScript variable.

After that, you can transfer the **ID** into an Endtest variable by using the **Extract value from JS variable** option from the **Set Variable** action.

This will allow you to join that Endtest variable with other strings and variables in the `Go to URL` steps to access certain sections from your **Chrome Extension**.
