  /*
  This test suite replaces the typical pytestCheckHook function in python
  packages. Pgadmin4 test suite needs a running and configured postgresql
  server. This is why this test exists.

  To not repeat all the python dependencies needed, this test is called directly
  from the pgadmin4 derivation, which also passes the currently
  used propagatedBuildInputs and any python overrides.

  Unfortunately, there doesn't seem to be an easy way to otherwise include
  the needed packages here.

  Due the the needed parameters a direct call to "nixosTests.pgadmin4" fails
  and needs to be called as "pgadmin4.tests"
