Is it possible to use Faker to simulate currency conversion errors

Example of Simulating Currency Conversion Errors

1. Generate Random Currency Data:
Use Faker to generate random currency codes and amounts.

php
   $faker = Faker\Factory::create();

   // Generate random currency codes
   $currencyFrom = $faker->currencyCode(); // e.g., 'USD'
   $currencyTo = $faker->currencyCode(); // e.g., 'EUR'

   // Generate a random amount
   $amount = $faker->randomFloat(2, 1, 1000); // Random amount between 1 and 1000
   

2. Simulate Missing Exchange Rates:
Create a condition to simulate an error, such as missing exchange rates for a specific currency pair.

php
   // Example of a predefined set of exchange rates
   $exchangeRates = [
       'USD' => ['EUR' => 0.85, 'JPY' => 110],
       // Missing rate for 'INR'
   ];

   // Check if the conversion is valid
   if (!isset($exchangeRates[$currencyFrom][$currencyTo])) {
       throw new Exception("Currency conversion error: Missing exchange rate for $currencyFrom to $currencyTo.");
   }

   // If valid, perform conversion
   $exchangeRate = $exchangeRates[$currencyFrom][$currencyTo];
   $exchangedAmount = $amount * $exchangeRate;
   

3. Output the Results:
You can handle the exception and output the error message.

php
   try {
       // Conversion logic here
   } catch (Exception $e) {
       echo $e->getMessage(); // Outputs: Currency conversion error: Missing exchange rate for USD to INR.
   }
