GetMockBuilderGetMockToCreateMockRector

Remove getMockBuilder() to createMock()

 use PHPUnit\Framework\TestCase;

 final class SomeTest extends TestCase
 {
     public function test()
     {
-        $applicationMock = $this->getMockBuilder('SomeClass')
-           ->disableOriginalConstructor()
-           ->getMock();
+        $applicationMock = $this->createMock('SomeClass');
     }
 }

Configure your rector.php:

<?php

use Rector\Config\RectorConfig;
use Rector\PHPUnit\PHPUnit60\Rector\MethodCall\GetMockBuilderGetMockToCreateMockRector;

return RectorConfig::configure()
    ->withRules([
        GetMockBuilderGetMockToCreateMockRector::class,
    ]);
