Thorough testing is paramount to ensuring the reliability and functionality of your software. This is especially true when you are developing with bitcoin where any small flaw could cost you or your customers real money. However, when it comes to testing applications on bitcoin, most developers use regtest for initial local testing, and testnet (tBTC) when ready to test on a network.
It is best practice to store bitcoin values in satoshis, not floats. Floats lead to a wide variety of problems which could even open your app up to exploits. There are 100,000,000 satoshis in every bitcoin and MySQL's integer limit of 32 bits, or 2,147,483,647, means the largest amount your app can handle would be 2.14 billion satoshis or (21.47 BTC). In other words, your application needs to be throughly tested to ensure it can handle transactions larger than 32 bits. The hardest lesson is launching your app only to find out later that the big deposit your important customer trusted you with was lost because you relied on faucets for testing and didn't test your app throughly enough.
To fully test your application's ability to handle large integer values, you'll need a significant amount of testnet Bitcoin. For example, to test a 32-bit application's ability to handle values larger than 32 bits, you'll need at least 21.48 tBTC.
While testnet faucets can provide small amounts of testnet Bitcoin for testing, they typically only provide 0.003 tBTC or less, making it impractical to acquire large sums through faucets alone, and 0.003 tBTC is insufficient for testing purposes.
Mining testnet Bitcoin is another option, but it can be time-consuming and costly. For example, mining 21.47 tBTC would take at least 86 days (at the current difficult of 97M) and cost over $600 in electricity costs (3250 watts @ $0.09KW/h) if using a popular mining hardware like the S19 Antminer.

The most efficient solution is to purchase large sums of tBTC for testing purposes. This allows you to quickly and cost-effectively acquire the amount of testnet Bitcoin needed to thoroughly test your application's ability to handle large integer values.
So when it comes to testing applications that involve large integer values having a significant amount of testnet Bitcoin (tBTC) is crucial. MySQL's integer limit of 32 bits, or 2,147,483,647, means that a 32-bit app can only handle up to 21.47 Bitcoin. To fully test your app's ability to handle integers larger than 32 bits, you'll need at least 21.48 tBTC. However, testnet faucets typically only provide 0.003 tBTC or less, making it impractical to acquire the necessary amount through faucets alone. Mining is too costly and time-consuming for testing purposes. The best option is to purchase testnet bitcion, and we hope to be your trusted source whenever you need to purchase tBTC.
