can you add a test case?

I was able to setup my test environment but now I'm having issues faking the metadata object.

$metaData = $this->getMock('Metadata\MetadataInterface');

$metaData
    ->expects($this->once())
    ->method('offsetGet')
    ->willReturn("1")
;

$metaData->offsetGet();
// Call to undefined method Mock_MetadataInterface_7f3f507c::offsetGet()

Am I missing something obvious? I don't even know where MetadataInterface is defined (I see in ImageInterface that metadata is supposed to return a Metadata\MetadataInterface).

this interface is part of the "jms/metadata" composer package I guess .. but what makes you believe you need to mock this interface for a test?

The autorotate needs to get the metadata from the image to know the rotation. So I want to mock it, to avoid having to provide real pictures.

I found the info on https://imagine.readthedocs.org/en/latest/usage/metadata.html. The metadata function returns a Imagine\Image\Metadata\MetadataBag.

I added the test cases and followed StyleCI recommendations.

the style issues were already fixed in master .. it would be best if you start a new branch from current master and cherry pick your changes into there.

Actually I only fixed the StyleCI issues for the files I modified.
I still created a new PR #654
