<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">You could flush out simple logic errors, syntax errors and so on by presenting test images, but checking that things were done and not the output images.<br>
<br>
You could also create minimal test images of 4 pixels by 4 pixels (or some similar tiny block), and a result image of the same size - at that size, a simple comparison would work. This may only be appropriate for some image processing. The theory is that for
most processes, the result of a given input is deterministic - so go for the simplest possible way to ensure this.<br>

<span>I'm learning unit testing in python and I need to try it in image processing. But I can't think of any test case which is applicable in image processing domain. I work with images in my application and it's very different from checking the result of adding
two values. Does anyone have any suggestion or knows of a reference which can help me to design unit tests in image processing domain?</span></div>
