Java jacoco code coverage

JaCoCo is a tool for measuring code coverage in Java applications. It can be used to determine how much of your code is being executed during testing and to identify areas of your code that are not being adequately tested.

To use JaCoCo to measure code coverage in your Java project, you can follow these steps:

1. Add the JaCoCo dependency to your project's build configuration file (e.g., pom.xml for Maven projects or build.gradle for Gradle projects).
2. Configure your build tool (e.g., Maven or Gradle) to run JaCoCo during the test phase of your build.
3. Run your tests as you normally would. JaCoCo will automatically instrument your code and record coverage information while your tests are running.
4. After your tests have completed, JaCoCo will generate a code coverage report. The report will contain information about which lines of code were executed and which were not, as well as other statistics such as branch coverage and complexity metrics.

You can view the generated report using a tool such as the JaCoCo command-line interface or the Eclipse EclEmma plugin. The report can also be integrated into your continuous integration (CI) workflow by using tools such as Jenkins or SonarQube.

For more information on using JaCoCo to measure code coverage in your Java projects, you can refer to the JaCoCo documentation or other online resources.
