New test-case too unspecific

[haesleinhuepf]

Hi Riccardo @rmassei,

in a new test-case suggested in #142, the test seems impossible to pass for me. I'd say that humans could not solve this with the given set of instructions and the expected solution:

image_metadata_reading.ipynb.txt

I'm in particular concerned about the docstring and the assert statement.

docstring:

Read images proprieties (i.e. shape, dimensions) from a tif file

assert:

expected_proprieties = "ImageProperties(shape=(20, 10), dtype=dtype('uint8'), n_images=None, is_batch=False, spacing=(5.0, 5.0))"
assert result_proprieties == expected_proprieties

If generated code would return a dictionary with dtype and shape, it would fulfill the description, but the test would fail. If you have time, please rephrase the docstring and the assert-statement so that humans and LLMs could pass the test, ideally without using this exact syntax from imageio.

Thanks!

Best,
Robert
