Isolated unit testing patterns for Spring service layer using Mockito and JUnit 5.
Automate repetitive workflows and reduce manual effort
Example: Generate reports, summarize documents, draft communications
Save 3-5 hours per week on routine tasks
Learn new skills, understand complex topics, get expert guidance
Example: Explain concepts, provide examples, suggest learning resources
Accelerate learning and skill development by 2x
Enhance output quality through reviews, suggestions, and refinements
Example: Review drafts, suggest improvements, catch errors
Improve work quality by 30-40% with less effort
Time estimate: 15-45 minutes depending on use case complexity

Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionunit-test-service-layerExecute the skills CLI command in your project's root directory to begin installation:
epx add giuseppe-trisciuoglio/developer-kit --skill unit-test-service-layerFetches unit-test-service-layer from giuseppe-trisciuoglio/developer-kit and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
