Probe that using Cursor rules for Agile & Java are useful when the Software Engineer have to face non trivial Java problems.

• https://github.com/jabrena/latency-problems

Intall the cursor rules which you are going to use in your workspace

sdk install jbang jbang --fresh setup@jabrena jbang setup@jabrena init --cursor https://github.com/jabrena/cursor-rules-agile

Generate the software requirements based on the initial problem description

Create an agile development checklist using @2000-agile-checklist

Note: The Cursor rules for Agile could help several roles: EA, PO, BA, SA, TL, SSE & SE.

Note: Using the Cursor rules for agile, the implementation phase and the models provided by Cursor will have better context information to be used in the implementation & testing phase.

• 4.1 Setup the Maven project

Depending of the requirements and the requirements will use one command or another:

jbang setup@jabrena init --maven jbang setup@jabrena init --spring-boot jbang setup@jabrena init --quarkus

• 4.2 Implement the Acceptance test (Outside-in TDD London) based on the Gherkin file described in the implementation.

Note: Attach the User story & Gherkin file from requirements folder

Implement an acceptance tests in the package info.jab.latency for the scenarios Don´t develop any source code, only implement the acceptance test. It will fail because in this phase, doesn´t exist any implemention.

• 4.3 Implement the solution to pass the acceptance tests

Implement a solution in the package info.jab.latency from src. Create a solution and later add test classes. Dont´t change the acceptance tests. Verify the changes with the command: ./mvnw clean verify

• 4.3 Implement the solution to pass the acceptance tests

Note: At the end of this phase, the development should build with ./mvnw clean verify and at runtime the solution will work.

• 4.4 Implement the rest of the requirements.

Note: Follow the task list in orther to build the solution in a incremental way.

• 5.1 Increase the Code coverage

Review current state with:

./mvnw clean verify jacoco:report -Pjacoco jwebserver -p 8002 -d "$(pwd)/target/site/jacoco"

And improve the test coverage:

Review the coverage with ./mvnw clean verify jacoco:report -Pjacoco and increase the coverage in instructions, classes & branches until 80% @problem4

• 5.2 Refactor the initial stable solution

Review current implementation to have a high level view what is the current implementation:

Create the UML diagram based on @example/implementation/src/main/java using the cursor rule @2200-uml-class-diagram.mdc

Generate the png files on-fly with the following utility:

jbang --fresh puml-to-png@jabrena jbang puml-to-png@jabrena --watch problem5/requirements

Note: Review all files if something is possible to be simplified.

• 5.3 Enrich the solution

Install the specific cursor rules for Java

jbang setup@jabrena init --cursor https://github.com/jabrena/cursor-rules-java #TODO: Create a checklist for the java cursor rules

Note: No recipe, this is the added value of a good SSE. ¯_(ツ)_/¯```

Enjoy in the refactoring process
