Partial mock of static class of phpunit operation

Know from official documents and practices , Classes with static methods, if needed mock, Use prefix alias: , However, there is a problem that the method of the class itself cannot be called later , So by reading the source code, you can use the following methods to achieve ：

1. establish Helpers Class to encapsulate

<?php

use Mockery;
use Mockery\Generator\MockConfigurationBuilder;

class Helpers
{
    /**
     * Mock static class, you can call the original method and mock the method
     * mock  Static class , You can call the original method , Again  mock  Method 
     * @param string $class
     * @param string $cloneClassNameSuffix
     * @return Mockery\Mock
     * @throws \Exception
     */
    public static function mockAliasPartial($class, $classRealPath, $cloneClassNameSuffix = 'UnitOrigin') {
        $sourceCode = file_get_contents($classRealPath);
        preg_match('/class\s+([A-Z]\w+)/', $sourceCode, $match);
        $className = $match[1] ?? '';
        if (empty($className)) {
            throw new \Exception('get class name failed!');
        }
        $cloneSourceCode = preg_replace('/class\s+([A-Z]\w+)/', 'class ' . $className . $cloneClassNameSuffix, $sourceCode, 1);
        eval("?>" . $cloneSourceCode);
        
        $builder = new MockConfigurationBuilder();
        $builder->setInstanceMock(true);
        $builder->setName($class);
        $target = '\\' . $class . $cloneClassNameSuffix;
        return Mockery::mock($target, $builder)->makePartial();
    }
}

2. Create static classes

class Test
{
    public static function getName($name) {
        if (empty($name)) {
            return 'default_name';
        }
        return $name;
    }
}

3. test run

<?php

use PHPUnit\Framework\TestCase;


class UniTest extends TestCase
{
    public function testAliasPartial() {
        $mock = Helpers::mockAliasPartial(Test::class, './Test.php');
        $actual1 =  Test::getName('');
        echo PHP_EOL;
        $mock->shouldReceive('avatar_small')->andReturn('fake name');
        $actual2 = Service::getName('');
        
        $this->assertEquals('default_name', $actual1);
        $this->assertEquals('fake name', $actual2);
    }
}
