The neo-forgery tool is a powerful stub that mocks a real Neo4j-driver session, allowing developers to create code and test it without making additional calls to their database. By utilizing this tool, Neo4j users can now enjoy the benefits of Test-Driven Development (TDD) and complete test coverage in their node applications. The tool provides an efficient way to stub out server calls, including queries that use a session object generated by the driver. It works well and allows developers to quickly create tests without worrying about the underlying database interactions. With neo-forgery, developers can focus on writing unit tests and ensuring their code is reliable and stable.
