Visual Regression Testing Utilizing Apify and AI Vision Model

How it works

The workflow titled "Visual Regression Testing Utilizing Apify and AI Vision Model" is designed to perform visual regression testing on user interfaces by leveraging Apify and an AI vision model. The workflow consists of several interconnected nodes that facilitate the process of capturing screenshots, analyzing visual differences, and reporting the results.

1. Start Node:

The workflow begins with a trigger node that initiates the process, typically set to run on a schedule or manually.

2. Apify Node:

The first operational node is the Apify node, which is configured to run a web scraping task. This node captures screenshots of the specified web pages. The configuration includes the URL of the page to be tested and any necessary parameters for the scraping task.

3. Image Processing Node:

After capturing the screenshots, the workflow proceeds to an image processing node. This node utilizes an AI vision model to analyze the screenshots. It compares the newly captured images against baseline images to detect any visual discrepancies.

4. Comparison Logic:

The results from the AI vision model are processed to determine if any significant changes have occurred. This involves setting thresholds for acceptable visual differences, which are defined in the node's configuration.

5. Notification Node:

If differences are detected that exceed the defined thresholds, the workflow triggers a notification node. This node can send alerts via email, Slack, or other communication channels to inform the relevant stakeholders about the visual changes.

6. End Node:

Finally, the workflow concludes with an end node, which signifies the completion of the visual regression testing process.

Throughout the workflow, data flows seamlessly from one node to the next, ensuring that each step is executed in the correct order, with outputs from one node serving as inputs for the subsequent nodes.
