Classes and Interfaces to help you get higher test coverage
High Test Coverage is a collection of classes and interfaces designed to help you get higher test coverage when using impure parts of the PHP Standard Library. It provides a 'RandomInt' interface which you can use in place of the 'random_int' function, like so:
Pull down with composer:
composer require --dev ancarda/high-test-coverage
<?php
use Ancarda\HighTestCoverage\RandomInt\RandomInt;
final class Genie
{
public function __construct(private RandomInt $randomInt) {}
public function fortune(): string
{
return 'Your lucky number is ' . $this->randomInt(1, 10);
}
}
In production, this class would be given an instance of 'RandomInt\Real', likely via your Dependency Injection container. Under test, you would use one of the many built-in classes, such as 'Fixed' or 'OneShot', like so:
<?php
use Ancarda\HighTestCoverage\RandomInt\Fixed;
final class GenieTest extends TestCase
{
public function testFortune(): void
{
$genie = new Genie(new Fixed(42));
self::assertSame('Your lucky number is 42', $genie->fortune());
}
}
