# Test environment

  Alpine_Linux_3.12.10_bash_5.0.17_BusyBox_v1.31.1

# Testing rdlink version v0.3-0-g124ae12

  Testdate: 2022-03-23 10:20:57 UTC

# Conclusion

Output is still valid compared to `readlink -f` from the “GNU coreutils” package. `readlink` on BusyBox behaves slightly different.

After more results of different platforms are evaluated in the future, the tests may be shifted more to assert expected results rather than comparing output to readlink -f on each platform.
