Modelling Test Views for Graph Database Applications

Since NoSQL databases use data models, access modes and query languages that differ from the relational databases, the testing NoSQL database applications raises new challenges. There has been much attention to testing relational database applications, however testing NoSQL database applications is an area that has been hardly explored. This paper describes a model-based approach that allows the tester to model the important features of a graph database application to be tested, called test views. These test views are used to derive the test requirements that guide the generation of test cases. The approach is illustrated with an application that represents a real-world problem related with access control. The results show that using this model-based approach leads to test cases that are able to reveal faults and failures in both system specification and implementation.
