No way to require PHP 7.0 only (not a later version) using an annotation

[ondrejmirtes]

Hello,
there's no way to require a test to run on PHP 7.0 and not on PHP 7.1 if I have a test that tests specifically a situation that makes sense only on PHP 7.0. The @requires annotation means "this version and all later versions" so I have to use a custom if condition with markTestSkipped.

So a possible solution would be to use version constraints (like for example used by Composer). In your case that would be:

/**
 * @requires PHP ~7.0
 */
public function testRunsOnlyOn70 { /*… */ }

In order to maintain BC @requires PHP 5.6.3 must still be interpreted as @requires PHP <=5.6.3 @requires PHP >=5.6.3 for example. https://github.com/phar-io/version can be used for parsing the version constraints as it will be a dependency as of PHPUnit 6.1 anyway.

I think you mean @requires PHP >= 5.6.3 instead of @requires PHP <= 5.6.3.

Of course, thanks. Fixed the typo.
