SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires mvn, jacoco, and includes scripts (resource) components.

What problem does it solve?

This Skill automates the generation of detailed JaCoCo code coverage reports for Java classes, allowing developers to quickly assess the test coverage of their code.

Core Features & Use Cases

  • JaCoCo Integration: Utilizes JaCoCo to measure code coverage for Java classes.
  • Scope Selection: Supports selecting specific classes or running full suite coverage.
  • Report Generation: Outputs line, branch, and instruction coverage percentages.
  • Use Case: When you need to verify that a specific class or set of classes have been adequately tested.

Quick Start

Run coverage for the class 'MyClass.java' using the command: /java-coverage MyClass.

FAQPage Schema
How do I generate a JaCoCo code coverage report for specific Java classes?

To generate a JaCoCo code coverage report for specific Java classes, you can use a Maven-integrated tool that targets class-level analysis. This approach outputs line, branch, and instruction coverage percentages for the selected classes.

What is JaCoCo code coverage analysis used for in Java development workflows?

JaCoCo code coverage analysis is used in Java development workflows to measure how thoroughly tests exercise your code. It provides precise assessment of test coverage by analyzing class files and reporting on line, branch, and instruction execution.

Do I need Maven to run JaCoCo code coverage on a Java project?

Yes, you need Maven to run this specific JaCoCo code coverage process. The analysis requires both Maven and JaCoCo dependencies to evaluate the Java class files and successfully produce the coverage reports.

Can I measure branch and line coverage for a single Java class instead of the full suite?

Yes, you can measure branch and line coverage for a single Java class instead of the full suite. The coverage generation supports scope selection, allowing you to target specific classes like 'MyClass' or run analysis across the entire project.

What's the best way to verify that a specific Java class has been adequately tested?

The best way to verify a specific Java class has been adequately tested is by generating a JaCoCo code coverage report. This provides precise assessment of test coverage by outputting line, branch, and instruction coverage percentages for the targeted class.

Why does my Java code coverage report only show class-level metrics?

Your Java code coverage report shows class-level metrics because the analysis specifically focuses on class-level coverage assessment for Java development workflows. It evaluates compiled class files using JaCoCo to output line, branch, and instruction percentages.
