The workshop „Let’s Disassemble A Monolith“ is coming to Frankfurt/Main in December 10th/11h this year! Attendees will learn how to deal with the challenge of extracting Microservices from monolothic Java systems. This is performed in a hands-on way using the example of a real-world open source Java eCommerce system. One of the key aspects is…
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!

Today we’re proud to announce a new plug-in for the jQAssistant ecosystem: The jQA Java DDD plug-in! With this new jQAssistant plug-in it’s easily possible to map the well-known concepts of Domain-Driven Design to your codebase, make the information available in the graph for querying and defining architectural constraints on them. To accomplish this, the…

In discussions with jQAssistant users we’re repeatingly asked about the following scenario: analysis and refactoring of monolithic Java systems. These have usually aged over many years and are packed with business critical functionality, implemented by many developers that joined and left the project taking their knowledge away. Since quite some time there’s now also a…
