| """Test asmap config argument for ASN-based IP bucketing. | |||||
| Verify node behaviour and debug log when launching bitcoind in these cases: | |||||

| 2. `bitcoind -asmap=<absolute path>`, using the unit test skeleton asmap | |||||
| 3. `bitcoind -asmap=<relative path>`, using the unit test skeleton asmap | |||||
| 4. `bitcoind -asmap/-asmap=` with no file specified, using the default asmap | |||||
| 5. `bitcoind -asmap` with no file specified and a missing default asmap file | |||||
| 6. `bitcoind -asmap` with an empty (unparsable) default asmap file | |||||
