Stripe Test Cards Helper

Floating button for selecting and copying Stripe test card numbers.

# Stripe Test Cards Helper ## Overview Stripe Test Cards Helper is a powerful and efficient Chrome extension designed to simplify testing payment forms. It provides a floating, draggable button on any webpage, allowing developers, QA teams, and testers to quickly access and insert pre-configured Stripe test card details. This extension automates the paste sequence for test card inputs, reducing manual entry and speeding up your testing workflow. ## Features - **Floating Draggable Button:** A non-intrusive button that remains on the page and can be repositioned near Stripe input fields for quick access. - **Test Card Overlay:** Clicking the floating button opens a modal overlay displaying a searchable list of test cards, complete with names, descriptions, and card numbers. Users can also mark frequently used cards as favorites. - **Automated Paste Sequence:** When a test card is selected, the extension automatically pastes the details in sequence: 1. **First CTRL+V:** Pastes the card number. 2. **Second CTRL+V:** After a short 100ms delay, pastes the expiration date (MM/YY, e.g., **12/34**). 3. **Third CTRL+V:** After another 100ms delay, pastes the CVV code (e.g., **567**). - **User Guidance:** The overlay includes a brief guide explaining the paste sequence, ensuring users understand how the automation works. ## Use Cases - **Web Development & Testing:** Quickly populate payment fields with test data, streamlining checkout flow and payment integration testing. - **Quality Assurance:** Automate repetitive input tasks and accelerate regression testing for various test scenarios. - **Demos & Training:** Effortlessly simulate payment processes during live demonstrations or training sessions without manual copy-pasting. ## How It Works 1. **Activation:** The extension activates per domain. Once enabled, a floating button appears on the page. 2. **Floating Button:** The draggable button can be moved anywhere on the screen. A click opens the test card overlay. 3. **Selecting a Test Card:** Users can search for and select a test card from the overlay. Upon selection, the card number is immediately copied, and the automated paste sequence begins. 4. **Automated Paste Sequence:** - **First CTRL+V:** Pastes the card number. - **Second CTRL+V:** After a 100ms delay, pastes the expiration date (MM/YY, e.g., 12/34). - **Third CTRL+V:** After another 100ms delay, pastes the CVV code (e.g., 567). ## Privacy and Security - **Local Data Storage:** All settings (including favorite cards and button positions) are stored locally using Chrome's extension storage API.
