Testing

Thus far you have seen that you design the Full definition for data model (opens in a new tab)The labels, relationship types and properties chosen to represent a domain. on paper, whiteboard, or with a tool like Arrows app. You use the use cases to design the data model that includes Full definition for label (opens in a new tab)A tag on a node that groups it with other nodes of the same kind. A node can carry more than one. for Full definition for node (opens in a new tab)A vertex in a graph. In a property graph it can carry labels and properties., Full definition for relationship (opens in a new tab)A named, directed connection between two nodes. Every relationship has a type, a start node and an end node. types and direction, and Full definition for property (opens in a new tab)A named value stored on a node or a relationship. for the nodes and relationships.

You have also populated the graph to implement the data model with a small set of test data. To ensure that the graph can satisfy every use case, you must test the use cases against the graph.
