- added RunnableTestCase::assertOriginalAndFixedFileYieldSameResult($file)
that takes a fixture file and expects fixture classes that implement the
new RunnableInterface which exposes a run() method
- the fixture class is dynamically renamed to avoid naming conflicts
and loaded via eval()
- fixtures that don't implement the RunnableInterface are ignored
otherwise the run() method is called on the original class as well
as on the fixed one and the output is expected to be equal
(via assertSame)
- fixed typo in RectorDefinition code sample
- fixed argument order of array_key_exists
- renamed test folder from ArrayKeysAndInArrayToIssetRector
to ArrayKeysAndInArrayToArrayKeyExistsRector
