How to Setup Visual Testing with Argos on Next.js

Visual testing is an important aspect of ensuring the quality and consistency of web applications. With Argos, a visual testing tool, you can easily set up visual testing for your Next.js applications. In this article, we will walk you through the process of setting up visual testing with Argos on Next.js.

Step 1: Install Argos

The first step is to install Argos as a dev dependency in your Next.js project. You can do this by running the following command in your terminal:

npm install --save-dev @argos-ci/cli

Step 2: Configure Argos

Once Argos is installed, you will need to configure it for your Next.js project. Create a new argos.config.js file in the root of your project and add the following configuration:

    module.exports = {
      pages: [
        {
          url: 'http://localhost:3000/',
          name: 'homepage',
        },
        // Add more pages as needed
      ],
    }
    

In this configuration, you can specify the pages of your Next.js application that you want to include in the visual testing. Be sure to replace the url and name with the appropriate values for your application.

Step 3: Run Argos

With Argos configured, you can now run the visual testing by running the following command in your terminal:

npx argos

This will start the visual testing process and generate a report of any visual changes detected in your Next.js application.

Step 4: Integrate with CI/CD Pipeline

Finally, you can integrate Argos with your CI/CD pipeline to automate the visual testing process. You can add a step in your pipeline to run the npx argos command and fail the build if any visual changes are detected. This ensures that any visual changes are caught early in the development process.

With these steps, you can easily set up visual testing with Argos on your Next.js application. This will help you ensure the visual consistency and quality of your application, making it a crucial part of your testing strategy.

Happy testing!
