Flip a ->with($this->callback(...)) matcher on a void mocked method to a ->willReturnCallback() call, dropping the value return and typing the closure as void
use PHPUnit\Framework\TestCase;
final class SomeTest extends TestCase
{
public function test()
{
$this->createMock(SomeClass::class)
->method('run')
- ->with($this->callback(function ($arg) {
+ ->willReturnCallback(function ($arg): void {
echo $arg;
-
- return true;
- }));
+ });
}
}
final class SomeClass
{
public function run($arg): void
{
}
}Configure your rector.php:
<?php
use Rector\Config\RectorConfig;
use Rector\PHPUnit\CodeQuality\Rector\Class_\VoidMethodWithCallbackToWillReturnCallbackRector;
return RectorConfig::configure()
->withRules([
VoidMethodWithCallbackToWillReturnCallbackRector::class,
