如何使用Stripe测试卡模拟余额不足导致的交易失败场景

Hey there! Testing failure scenarios is crucial to ensure your app gracefully handles edge cases—great call asking about this. Stripe provides dedicated test card numbers to simulate all kinds of failed transactions, including the insufficient funds case you mentioned. Here’s a breakdown of the most useful ones:

• Insufficient funds: Use the test card number 4000 0000 0000 0002. When you process a charge with this card, Stripe will simulate a "balance too low" failure, returning the insufficient_funds error code. Perfect for testing how your app handles users who try to make a purchase they can’t afford.
• Generic card decline: If you need to test a general "card declined" scenario (without a specific reason), use 4000 0000 0000 0003. This triggers the card_declined error, which is useful for testing your default decline handling flow.
• Expired card: Grab 4000 0000 0000 0069 and set the expiration date to any past month/year (like 01/20). Stripe will return the expired_card error, letting you validate your expired card warning and retry flows.
• Incorrect CVV: Take the standard success Visa card 4111 1111 1111 1111 and enter an invalid CVV (e.g., 000, or a 2-digit number). This will trigger the incorrect_cvc error, so you can test your CVV validation and error messaging.
• Processing error: For simulating unexpected gateway/network failures, use 4000 0000 0000 0119. This returns the processing_error code, which helps you test retry logic or user-facing messages for transient issues.

A quick reminder: All these cards only work in Stripe Test Mode—make sure you’ve switched to test mode in your Stripe Dashboard before using them. They won’t work in production, so no risk of real charges!
