Hi @hkchekc! Thanks for adding some more tests!
Currently the new tests are failing because of an incomplete path to the test files. You can get the correct path by using self.get_filename_path(filename).

[JuliaSprenger]

And you need to inherit from BaseTestIO to have this function available. You can compare to https://github.com/NeuralEnsemble/python-neo/blob/master/neo/test/iotest/test_blackrockio.py as an example implementation.

[hkchekc]

One test will fail now due to a bug which will be fixed in the PR #581
This is merged.

[JuliaSprenger]

@hkchekc: You will also need to adjust the conversion of nix attributes to regular python objects, because nix objects are not supported by neo eg. as annotations.

[hkchekc]

We upload a new nix file for test on Gin.

[JuliaSprenger]

I merged the new file and rerun the tests. However, they are still failing somewhere within nix when parsing the header. Do you have an idea how to fix this?

[JuliaSprenger]

@hkchekc: Thanks for fixing the CI tests.
I still get an error when running the tests locally with numpy 1.15.1 and nixio 1.5.0b2

Failure
  File .../python-neo/neo/rawio/tests/common_rawio_test.py", line 151, in test_read_all
    compliance.read_analogsignals(reader)
  File ".../python-neo/neo/rawio/tests/rawio_compliance.py", line 144, in read_analogsignals
    assert raw_chunk.ndim == 2
AssertionError

It seems that raw_chunk.ndim ==1 in at least one case here. Do you have an idea why this might be the case?

[hkchekc]

@JuliaSprenger I try to use numpy 1.15.1 and nixio 1.5.0b2 to run the test_nixio_fr.py and test_nixrawio.py for both 'nixrawio-1.5.nix' and ' nixio_fr.nix' and could not reproduce the error.

Can you tell me more details?

I used Python3.5 and 3.7

[JuliaSprenger]

Hi @hkchekc,
I had a closer look and think that the error was somehow related to an improper setup of my environment. If I create a new environment everything works smoothly. Sorry for the confusion.
I will merge this now.

Thanks for all the checkings! @JuliaSprenger
