Plus the same problem as here: clarity-h2020/simple-table-component#4 (comment)

It's always 'nice' to see your tests failing not because of changes in code or tests specs but in the test environment itself. 😲

Fix: axios/axios#1754 (comment)

[p-a-s-c-a-l]

log.debug() in beforeAll is not printed to console when running the tests in VSCode. See also jestjs/jest#2441

[p-a-s-c-a-l]

don't expect that this will work on an ip6 capable system if server adress is ::1

http://${server.address().address}:${server.address().port}

hard-code http://localhost:${server.address().port} instead. 👎

Works locally but not on CI:

BTW, remote tests shouldn't be executed on CI, because .env.test.local is no present.!
It seems that it.onlydoesn't work any more as expected.
