[ECS] Prefixed version and custom sniff testing has misses parent test case

[TomasVotruba]

@TomasVotruba I've installed dev-main, now I got Class 'Symplify\PackageBuilder\Testing\AbstractKernelTestCase' not found in .../vendor/symplify/easy-coding-standard/src/Testing/PHPUnit/AbstractCheckerTestCase.php:19. Ohhhh.

Hi, @TomasVotruba
any updates or ideas how to fix it?

[TomasVotruba]

Hi, I would create reproducible repository and try to update AbstractCheckerTestCase namespace in the /vendor, untill it works. Then apply the manual change in as a script in scoper.php file.

Ok, so I've created reproducible repository https://github.com/ERuban/ecs-testing-issue-example
Have tried to do some in the /vendor but without success.

After 2 days of work, I think I've made some progress. For future generations of scoping and downgrading explorers. There have been couple of bugs to solve this issue:

• make sure the regex starts and ends with same character 7cb57dc, otherwise there is silent error that leads to skipping whole file (I wish there was an exceptoin, but php-scoper ignores it)
• include scoper-autoload.php at the start of your project - 4c9c044, otherwise all un-scoped classes are ignored
• make sure you downgrade to correct version - to PHP 7.1, not to PHP 7.0, the PHPUnit will fail on extra void type then - 95f5ca6
• make the Abstract*TestCase as simple as possible, avoid to multiple inheritance that would require complex logic hard to debug - 826cd78

@ERuban Could you verify in your test repository? I tried it myself, but want to be sure it doesn't work only on my machine ;)

• use easy-coding-standard version dev-main

composer update

vendor/bin/phpunit

Hey, looks that it works in my test repo, great, thank you!
Waiting for the release ;)
