The first thing we do is moving the
util/env.go
into a new sub-packageenv/
. The package is now using an internalimpl
to be able to applyproperly mocked unit testing which is not dependent from the machine
they're running on.
Godoc can be used to demonstrate the isolation of the internal package.
We only have two functions exposed via the API, whereas the underlying
implementation can be changed from within our tests.
