# Neo4j to OrientDB Importer
## Documentation
http://orientdb.com/docs/last/OrientDB-Neo4j-Importer.html
## Internals
### Compile
```
mvn clean install
```
To skip tests:
```
mvn clean install -DskipTests
```
To run only a specific test, e.g. `shouldImportEmptyDb`:
```
mvn -Dtest=ONeo4jImporterTest#shouldImportEmptyDb test
```
### Tests
The test databases are created using the following queries:
#### graphdb\_empty\_db (test `shouldImportEmptyDb`)
Empty database
#### graphdb\_unique_constraints\_only (test `shouldImportUniqueConstraintsOnlyDb`)
```
CREATE CONSTRAINT ON (n:NodeLabelA) ASSERT n.p_number IS UNIQUE
CREATE CONSTRAINT ON (n:NodeLabelB) ASSERT n.p_string IS UNIQUE
CREATE CONSTRAINT ON (n:NodeLabelC) ASSERT n.p_boolean IS UNIQUE
```
#### graphdb\_nodes\_only (test `shouldImportNodesOnlyDb`)
```
foreach(x in range(1,10) | create (:NodeLabelA {p_number:x, other_property: "NodeLabelA-"+x}))
foreach(x in range(1,10) | create (:NodeLabelB {p_string:"string_value_" + x, other_property: "NodeLabelB-"+x}))
foreach(x in range(1,5) | create (:NodeLabelC {p_boolean:false, other_property: "NodeLabelC-"+x}))
foreach(x in range(6,10) | create (:NodeLabelC {p_boolean:true, other_property: "NodeLabelC-"+x}))
```
#### graphdb\_nodes\_only\_no\_labels (test `shouldImportNodesOnlyNoLabelsDb`)
```
foreach(x in range(1,10) | create ( {p_number:x, other_property: "string-"+x}))
foreach(x in range(1,10) | create ( {p_string:"string_value_" + x, other_property: "string-"+x}))
