Hello,

I’ve changed some code. A test fails. I can see my image file from the test run and compare it to the expected image file. The existing expected image file is now wrong and my new one is correct.  
However, I can’t find any instructions for where to put my new image? How and where do I commit it into the codebase?

Thanks,

Matt
