Following its deprecation in 20.03, the Perl NixOS test driver has been removed.
|
||||
All remaining tests have been ported to the Python test framework.
|
||||
Code outside nixpkgs using <filename>make-test.nix</filename> or
|
||||
<filename>testing.nix</filename> needs to be ported to
|
||||
<filename>make-test-python.nix</filename> and
|
||||
<filename>testing-python.nix</filename> respectively.
