php-parser/test/PhpParser/Internal/DifferTest.php
Lars Moelleken b7e6361536 updates via "rectorphp/rector" (#573)
- "global" -> remove unused "use" statements
- "phpunit" -> fix "@covers" comments
- "phpunit" -> replace "->will($this->returnValue()" with "->willReturn()"
- "UseTest.php" -> add missing namespace
- "composer.json" -> use "autoload-dev"
- remove -> "require_once" usage in the tests (use autoload-dev via composer.json)

-> most of the changes are done automatically by "https://github.com/rectorphp/rector"
