## Changes
Using an interface instead of a concrete type means we can pass
`*testing.T` directly or any wrapper type that implements a superset of
this interface. It prepares for more broad use of `acc.WorkspaceT`,
which enhances the testing object with helper functions for using a
Databricks workspace.
This eliminates the need to dereference a `*testing.T` field on a
wrapper type.
## Tests
n/a
## Changes
Two issues with this command:
* The command line arguments for the secret value were ignored
* If the secret value was piped through stdin, it would still prompt
The second issue prevented users from using multi-line strings because
the prompt reads until end-of-line.
This change adds testing infrastructure for:
* Setting up a workspace focused test (common between many tests)
* Running a snippet of Python through the command execution API
Porting more integration tests to use this infrastructure will be done
in later commits.
## Tests
New integration test passes.
The interactive path cannot be integration tested just yet.
