About Stripe Test Cards Helper

# 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. No sensitive data is transmitted externally. - **Test Environment Only:** This extension is strictly for development and testing purposes. It is not intended for use in production environments or with real payment data. ## Installation and Compatibility - **Easy Installation:** Install Stripe Test Cards Helper directly from the Chrome Web Store. - **Browser Compatibility:** Built using WebExtensions standards, this extension is fully compatible with Chrome. ## Disclaimer *Stripe Test Cards Helper is intended solely for testing and development environments. The automated paste sequence is designed to simulate test payment inputs. Do not use this extension in production or with real financial data.*
