# Test that library suggestions persist across file boundaries
|
|
|
|
This test verifies that the default library suggestion engine set in
|
|
`Lean.LibrarySuggestions.Default` is correctly persisted when imported via `Lean.LibrarySuggestions`.
|
|
|
|
We do NOT call `set_library_suggestions` in this file - the selector should
|
|
already be set from importing Lean.LibrarySuggestions (which imports Default).
