/* -------------------------------------------------
 *
 * This version of SapphireTest is for phpunit 9
 * The phpunit 5 version is lower down in this file
 * phpunit 6, 7 and 8 are not supported
 *
 * Why there are two versions of SapphireTest:
 * - phpunit 5 is not compatible with php 8
 * - a mimimum versin of php 7.3 is required for phpunit 9
 * - framework still supports php 7.1 + 7.2 so we need to support both versions for a while
 *
 * Once php 7.3 is the minimum version required by framework, the phpunit5 versions of SapphireTest
 * and FunctionalTest could be removed, along with the if(class_exists()) checks in this file
 * However, we still may choose to keep both until php 8 is the minimum to give projects more
 * time to upgrade their unit tests to be phpunit 9 compatible
 *
 * The used on `if(class_exists()` and indentation ensure the the phpunit 5 version function
 * signature is used by the php interprester. This is required because the phpunit5
 * signature for `setUp()` has no return type while the phpunit 9 version has `setUp(): void`
 * Return type covariance allows more specific return types to be defined, while contravariance
 * of return types of more abstract return types is not supported
 *
 * IsEqualCanonicalizing::class is a new class added in phpunit 9, testing that this class exists
 * to ensure that we're not using a a prior, incompatible version of php
 *
