Make use of pytest for testing and use GitHub Actions

[J535D165]

I think the pytest framework can be useful to test the package. It's more flexible and readable.

Also, making use of GitHub Actions would be nice.

Not very familiar with GitHub Actions, but seems nice 😄. Having automatic testing on push or deployment to PyPI on release would be very nice.

And I am okay with moving to pytest if that is recommended or better for GitHub Actions. I didn't have a strong reason for going with unittest. I'm a little tied up for the next couple weeks but could revisit after that.

Nice, happy to review.

Didn't get around to addressing this for at all for the new version. Still planning to look into this, but will need to do some learning & testing

[J535D165]

No worries. Version 0.4 is a nice improvement.

I'm working on a project, J535D165/scitree, which relies heavily on seedir. I want to propose some changes to the seedir API as I think they are both valuable for scitree and seedir. But the tests are holding me back at the moment. But there is no hurry for me :) Will work on this later.

That sounds great! Interested to hear your suggestions. Thanks for sharing your project, looks cool!

I generally want to improve/augment the testing suite for seedir. But still collecting my thoughts on what changes exactly. But I will port things to pytest as I am doing so
