	//go:debug asynctimerchan=0

Starting in Go 1.21, the Go toolchain treats a `//go:debug` directive
with an unrecognized GODEBUG setting as an invalid program.
Programs with more than one `//go:debug` line for a given setting
are also treated as invalid.
(Older toolchains ignore `//go:debug` directives entirely.)

The defaults that will be compiled into a main package
are reported by the command:

* Logging API

 Maven uses

 Container logging API}}, like any other Plexus components, ie

The file `main.py` would have:

The file `test_main.py` would have the tests for `main.py`, it could look like this now:

You can run your tests as usual via:
