Clear, Self-Explanatory Coverage Visualization That Helps Improve Code Quality **Rating:** 4.5/5.0 stars **Reviewed by:** Joyendra R. | Software Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** January 27, 2026 **What do you like best about JaCoCo?** Jacoco is very self explanatory. It's visualization of code coverage, per file, per package is very easy to understand. And then the legends in each file showing what part was left uncovered really help improving code coverage. **What do you dislike about JaCoCo?** When a branch is missed, it just puts it in yellow. That's difficult to navigate at times since some conditions have a lot of branches and without knowing exactly which branch was left uncovered, spot checking becomes a little difficult. **What problems is JaCoCo solving and how is that benefiting you?** Jacoco is maintaining a high bar in my codebase by ensuring a minimum of 90% code is covered. Any new line added to the code must be covered else the build fails which acts as a forcing function for people to ensure the right test cases are put in place before making any commits. But it also helps us devs to identify branches we might have genuinely left. ### 2. JaCoCo – Fast, Simple, Reliable Code Coverage Tool **Rating:** 5.0/5.0 stars **Reviewed by:** Srikant V. | Staff Software Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 30, 2025 **What do you like best about JaCoCo?** What I like best about JaCoCo is its simplicity and accuracy.

I also like that it works with unit tests automatically, no extra work needed. In short: simple, fast, reliable, and easy reporting. **What do you dislike about JaCoCo?** What I don’t like about JaCoCo is it only measures coverage, not quality of tests. Sometimes it shows 100% coverage but tests may still be weak. Also, debugging coverage issues in complex projects can be tricky. In short: coverage-only tool, no test quality check, tricky in big projects. **What problems is JaCoCo solving and how is that benefiting you?** aCoCo solves the problem of knowing which parts of your code are tested and which are not.

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. **What do you dislike about JaCoCo?** 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. **Recommendations to others considering JaCoCo:** Jacoco is the best Java code coverage analysis plugin for any Java project. And useful plugin to integrate with CI/CD pipelines. **What problems is JaCoCo solving and how is that benefiting you?** We had to integrate our Java projects with SonarQube. But when we initially did integration with SonarQube, the project didn't get the code coverage. Therefore we integrated the Jacoco plugin with our Java project and did easily uploaded the code coverage when the Sonar scan run. We completed our CI/CD pipeline flow, test coverage analysis thanks to Jacoco. ### 36.

Jacoco Code Coverage Plugin - Review **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Retail | Enterprise (> 1000 emp.) **Reviewed Date:** August 30, 2021 **What do you like best about JaCoCo?** 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. **What do you dislike about JaCoCo?** 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") **What problems is JaCoCo solving and how is that benefiting you?** 1. We build the Maven project with the JaCoCo plugin configured, you can run the Maven build in any CI pipeline, which will help improve code quality. 2. We run code coverage on our builds on Jenkins to publicly track the coverage measurements. 3. It helps us to identify the code line which is untested by our automation suite where need to write more unit/integration test. ### 40.
