pre-install-commands for test environment(s)

[13BTurbo]

When I try to run hatch test I get the following error:
No solution found when resolving dependencies. Because <my other package> was not found in the package registry and you require <my other package>, we can conclude that your requirements are unsatisfiable.

For my default and build envs, I use pre-install-commands to install <my other package> (in editable mode, from a sibling repository)
Can I do this for the test environment(s), it does not appear so, unless I'm missing something.

I've tried various combinations of:

[tool.hatch.envs.hatch-test]
[tool.hatch.envs.test]
[tool.hatch.envs.hatch-test.py.x.xx]
