Best practice for test data

[hkaspersen]

I have a nextflow pipeline that I need to supply some testdata to (fasta files) so that users may test the pipeline on this data.
The data itself isn't big, around 5 mb per file, and in total six files. However I am unsure whether this should go into the github repo or not?
The test itself is defined in the conf/test.config file, where I was hoping to define the input data with a URL or link, so that the user doesn't have to download anything to test it. Can I f.ex pass the data in like this:

params {
    input = "../testdata/*fasta"
}

In the config file if the data is uploaded to github? If that is not the best way, does anyone have any other suggestions on how to do this properly?
