linting for nf-test snapshot

[maxulysse]

Description of feature

Make sure that no input are snapshot by nf-test: As it will err if we change the path to the files:

• github: /nf-core/test-datasets/modules/data/genomics/sarscov2/illumina/fastq/test_1.fastq.gz
• s3: /ngi-igenomes/testdata/nf-core/modules/genomics/sarscov2/illumina/fastq/test_1.fastq.gz

can you link to an example where this was done? or is this hypothetical?

Can we control that no one snapshots an input file? I think we could check to not snapshot files from the test-datasets repo if that's in the path, but I am not sure we can check other files.

Closing as we think it's impossible to know what is an input file and what isn't. Can reopen if we get more information and examples to work with.
