We could provide our own testing module with a method similar to testing.Short() but for testing.External that would be called by test that call external services and return false by default except if a env variable is set ?

@sapk you mean only run github-migration-test if a env variable is set?

-> in this case we could use a gitHub-token as var witch is a drone secreat -> next problem solved

Yes that good enough (no need to over engineer this my bad).

I'll close this for now -> if a error occure on e.g. alpine ... migration test is skiped ... (by altering make test exeptions ...)
