Created May 11, 2025 17:33
A PHP function to perform date interval math in a reliable way for billing systems.
<?php declare( strict_types=1 );
final class Billing_Date_Interval {
const INTERVAL_ONE_DAY = 'day';
const INTERVAL_ONE_MONTH = 'month';
const INTERVAL_ONE_YEAR = 'year';
/**
* Add or subtract an interval to a date.

A class to get the current timestamp which can be overridden for tests.
<?php
declare( strict_types=1 );
/**
* Class to replace uses of `time()` or `new DateTime()` that allows
* overriding.
*
* This class should be used by everything in the billing system that needs to
* know the current time instead of calling `time()` or `new DateTime()`, etc.

// This is a little tricky because we need to verify that text never appears,

async function verifyThatTextNeverAppears( text: string ) {
await expect( screen.findByText( text ) ).rejects.toThrow();

// OR, a custom Jest matcher:
