Can JaCoCo be used for Scala?
JaCoCo is a great open-source toolkit for code coverage measurements. JaCoCo was originally written for Java and runs on the JVM, but because it’s bytecode-based it works for Scala too.
How do I check code coverage with JaCoCo?
To get code coverage reports in a Maven project, we first need to set up the JaCoCo Maven plugin for that project. By integrating the JaCoCo plugin, the results of the code coverage analysis can be reviewed as an HTML report. The current version of the JaCoCo-Maven plugin can be downloaded from the MVN Repository.
How do I add a JaCoCo plugin?
We can configure the JaCoCo Maven plugin by following these steps:
- Add the JaCoCo Maven plugin to the plugins section of our POM file.
- Configure the code coverage report for unit tests.
- Configure the code coverage report for integration tests.

Why does JaCoCo not show coverage?
Why does the coverage report not show highlighted source code? Make sure the following prerequisites are fulfilled to get source code highlighting in JaCoCo coverage reports: Class files must be compiled with debug information to contain line numbers. Source files must be properly supplied at report generation time.

What is SBT plugin?
A plugin can define a sequence of sbt settings that are automatically added to all projects or that are explicitly declared for selected projects. For example, a plugin might add a proguard task and associated (overridable) settings. Finally, a plugin can define new commands (via the commands setting).

SonarQube is used in integration with JaCoCo, a free code coverage library for Java.
What is JaCoCo branch coverage?
JaCoCo also calculates branch coverage for all if and switch statements. This metric counts the total number of such branches in a method and determines the number of executed or missed branches. Branch coverage is always available, even in absence of debug information in the class files.

Is JaCoCo and SonarQube same?
JaCoCo vs SonarQube: What are the differences? JaCoCo: A code coverage library for Java. It is a free code coverage library for Java, which has been created based on the lessons learned from using and integration existing libraries for many years; SonarQube: Continuous Code Quality.
How does SonarQube work with JaCoCo?
SonarQube and JaCoCo are two tools that we can use together to make it easy to measure code coverage. They also provide an overview of the overall health of the source code by finding code duplications, bugs, and other issues in the code. This helps us to know whether our code is production-ready or not.
