Is it better to cache API data or make multiple API calls in PHPUnit tests?

Caching API data in PHPUnit tests can improve test performance by reducing the number of API calls and speeding up test execution. However, it is important to ensure that the cached data is up-to-date and reflects the current state of the API. One approach is to cache the API response for a certain period of time and invalidate the cache when necessary. 

// Example of caching API data in PHPUnit tests

class APITest extends \PHPUnit\Framework\TestCase
{
    private $cachedData;

    public function testAPICall()
    {
        if (!$this->cachedData) {
            $this->cachedData = $this->fetchAPIData();
        }

        // Use $this->cachedData for assertions
    }

    private function fetchAPIData()
    {
        // Make API call to fetch data
        // Cache the data for future use
        return $apiData;
    }
}
