Bugfix: The testfile needs to handle the --build parameter and improve --work parameter handling.

Provide a new operation "build_path" to load the "--build" parameter properly.
The existing checks for the "--work" parameter is better suited checking against "work:value" rather than "work".

There may be an existing bug where the condition for "build" parameter is always returning true when it should not.
This requires further investigation and is not addressed within the scope of this commit.
