[CodeQuality] Rule to enforce test method code style

[Xammie]

This adds two rules to convert the name of test methods to either CamelCase or snake_case.

// When using
use Rector\PHPUnit\CodeQuality\Rector\ClassMethod\PreferTestsWithSnakeCaseRector
$rectorConfig->rule(PreferTestsWithSnakeCaseRector::class);

// From
public function testItWillCreateNewProduct() {}
// To
public function test_it_will_create_new_product() {}

@TomasVotruba this is ready to review :)

here ensure name is exists first before changing it, you can use Class_ instead of ClassMethod, and verify from $class->getMethod() or classReflection->hasMethod()

[samsonasik]

for additional note: I think this should be your own custom rule for your specific use case :)

[Xammie]

@samsonasik thank you for the review.

Regarding your additional note, do you mean this should not be part of rector php and instead be part of a separate package?

[samsonasik]

yeah, imo, this should be not part of rector repo, you can create your own custom rector rule for it as this is by preference

[Xammie]

The reason I thought it would fit well here is because this is similar to PreferPHPUnitSelfCallRector and PreferPHPUnitThisCallRector in a way, because that is mostly a preference in code style.

Ofcourse if you still don't think this should be part of rector-phpunit then I completely understand and I will put it into a new package.
