Will look into it.

Hi, is this feature the only way to run test of a decorated hydra function?
I have something like this with run decorated by hydra.main:

def test_main():
        experimental.initialize("../cfg/")
        cfg = experimental.compose("../cfg/config.yaml")
        run(cfg)

but it is not allowed.

currently there is no supported way to do it. this feature is exactly about supporting this use case.

you can work around this easily though:

def real_run(cfg):
  ...

@hydra.main(...)
def run(cfg):
  real_run(cfg)

def test_main():
        experimental.initialize("../cfg/")
        cfg = experimental.compose("../cfg/config.yaml")
        real_run(cfg)
