Error on HHVM due "configuration" global variable

[aik099]

PHPUnit creates configuration global variable, which is object of DOMDocument class. When running tests on HHVM and globals are backed up in the process this ends up in following error:

Attempted to serialize unserializable builtin class DOMDocument

See https://travis-ci.org/minkphp/phpunit-mink/jobs/114842726

Proposing to exclude global variable configuration, that PHPUnit creates for internal needs from serialization done in Snapshot class.

Not sure if it matters, but tests, that trigger such behavior are also marked with @runInSeparateProcess annotation.

The only place I can find where PHPUnit creates a global variable named $configuration is in the template that is used for executing a test in a separate process. That variable is now unset after it has been used, see a093bd8.

Are the tests you mention executed in process isolation? If so, does a093bd8 solve the issue for you?

Are the tests you mention executed in process isolation?

Exactly. I'm using @runInSeparateProcess annotation.

If so, does a093bd8 solve the issue for you?

Yes, it does. Thank you. Can you please backport this to PHPUnit 4.x release as well, because on Travis CI for HHVM the PHPUnit 4.x version only is installed.

This will be in the next PHPUnit 4.8 release, yes.

a093bd8 is in PHPUnit 4.8.24, closing.
