Quick Tip: Faking Dates in PHP with Carbon

CarbonTest.php

// Set test date to 12:00 on 18th June, 2018
$testDate = Carbon::create(2018, 6, 18, 12);
Carbon::setTestNow($testDate);

// Execute the logic
BusinessClass::doStuff();

// Check the results
$this->assertDatabaseHas('stuff', [
    // The data you need...
]);

// IMPORTANT: Reset the date to not affect the next test!
Carbon::setTestNow();
