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
