+"""Test asmap config argument for ASN-based IP bucketing.
+
+Verify node behaviour and debug log when launching digibyted in these cases:
+
+1. `digibyted` with no -asmap arg, using /16 prefix for IP bucketing
+
+2. `digibyted -asmap=<absolute path>`, using the unit test skeleton asmap
+
+3. `digibyted -asmap=<relative path>`, using the unit test skeleton asmap
+
+4. `digibyted -asmap/-asmap=` with no file specified, using the default asmap
+
+5. `digibyted -asmap` restart with an addrman containing new and tried entries
+
+6. `digibyted -asmap` with no file specified and a missing default asmap file
+
+7. `digibyted -asmap` with an empty (unparsable) default asmap file
+
+The tests are order-independent.
