Jacoco is power full plugin it is for getting report class wise lines and methods test coverage .it will provide html format output test case reports Review collected by and hosted on G2.com.

generating test code coverage report

So that we can identify how much code lines covererd for unit testing

So that we can know that any issues with developed software products Review collected by and hosted on G2.com.

The best part is its reporting structure and we able to get the test coverage reports in good readable format.And ofcourse helps us in test coverage and test scope. Review collected by and hosted on G2.com.

The configuration and runs on only the build shutdown Review collected by and hosted on G2.com.

- Excellent test coverage. Very reliable. Easily to plug into industry strength IDE. (eg: Plugins available for Jetbrains Intellij and Eclipse IDE)

- Low memory footprint Review collected by and hosted on G2.com.

Sometimes the plugin updates are incompatible with IDE version. I use Jetbrains Intellij. Review collected by and hosted on G2.com.

It supports many Java project types such as Maven and Gradle projects and easy to project analysis with the tools such as SonarQube. Jacoco support, code coverage reports export to many formats such as XML, PDF, and HTML reports, etc. As a Java developer, I mostly like the Jacoco providing good compatibility with JUnit and TestNG. Jacoco Jenkins pugin providing a good support to test integrations with Jenkins, therefore Jacoco Jenkins plugin helped us to complete our projects CI/CD pipelines in proper manner as we expected. Jacoco developer community also found many solutions when we integrate Jacoco to our Java projects. Review collected by and hosted on G2.com.

In web view in code coverage report, better to have more descriptive about the code coverage missing blocks with suggestions. Better if Jacoco can provide hints in test reports to cover the uncovered code lines or code blocks. We found some issues when we integrate Jacoco with the latest version of Junit, better if Jacoco can release a newer version with JUnit 5 support. Review collected by and hosted on G2.com.

1. It gives accurate and reliable code coverage for unit tests.

2. The results can be given out in different file formats, which can be represented as graphs.

3. It can also be integrated with Sonarcloud for static code analysis and merge checker. Review collected by and hosted on G2.com.

It can get a little confusing to integrate with Kotlin projects. Review collected by and hosted on G2.com.

I use jacoco plugin for the java code coverage library and use it with IntelliJ; I configured it with the maven plugin. So far, I like how it shows results on coverage and gives effect. Also integrated with build profile to see result. Review collected by and hosted on G2.com.

We're using SonarQube integrated with Jacoco Plugin to check on code smell, pmd, find bugs and not showing coverage for some classes. Review collected by and hosted on G2.com.

It automatically generates an HTML report containing all test results, including coverage reports with line and branch coverage. Review collected by and hosted on G2.com.

Nothing really, it's an excellent plugin that I use with all my projects Review collected by and hosted on G2.com.

1. JaCoCo is a free code coverage library for Java, and hence no additional cost overhead for the team.

2. HTML report is the most human-readable report and easy to interpret. XML report is mainly used to integrate with other tools or dashboards, e.g., SonarQube

3. Jacoco coverage report can be merged with CI/CD with Jenkins

4. User can check from comprehensive report to single method coverage report. It measures line and branch coverage based on running unit test cases, along with integration tests. It provides visual information, including highlighted lines of code and the total percentage of code executed in each method.

5. Recently migrated from Cobertura to Jacoco as Cobertura is outdated (no more extended support Java versions above 7, and newer JDK versions).

It supports and allows Jacoco new users to use other teams' Jacoco configuration' as a guide. Review collected by and hosted on G2.com.

1. Jacoco should add an option to ignore/mark switch default cases as covered.

2. Only class-level exclusion is available

3. Any annotation with "Generated" in the name is filtered and not included in the code coverage. "Generated" in the name doesn't mean that it should be screened from code coverage.

4. Jacoco HTML report shows missing instruction on the line with @SuppressWarnings("unused") Review collected by and hosted on G2.com.

Easy integration with maven project and provides an excellent report on the code coverage, which helped us improve the application health matrix. Review collected by and hosted on G2.com.

It requires java agent as a JVM parameter. Review collected by and hosted on G2.com.

JaCoCo is by far one of the best Code Coverage Plugins that I use in all of My Java Projects; It provides a very detailed HTML Report of your Unit Tests. Review collected by and hosted on G2.com.

I do not have any issues with JaCoCo, this by far the best Code Coverage Plugin for Java Projects. Review collected by and hosted on G2.com.
