jQAssistant is a QA tool, which allows the definition and validation of project specific rules on a structural level. It is built upon the graph database Neo4j and can easily be plugged into the build process to automate detection of constraint violations and generate reports about user defined concepts and metrics.
Example use cases:
- Enforce naming conventions, e.g. EJBs, JPA entities, test classes, packages, Maven modules etc.
- Validate dependencies between modules of your project
- Separate API and implementation packages
- Detect common problems like cyclic dependencies or tests without assertions
Rules are expressed in Cypher - the easy-to-learn query language of Neo4j:
MATCH (t:Test:Method) WHERE NOT (t)-[:INVOKES]->(:Assert:Method) RETURN t AS TestWithoutAssertionGet started here!
