What Is Jacoco Branch Coverage?
Jacoco Mainly Provides Three Important Metrics: Lines Coverage Reflects the Amount of Code That Has Been Exercised Based on the Number of Java Byte Code...

Likewise, what is branch code coverage?
Branch coverage is a testing method, which aims to ensure that each one of the possible branch from each decision point is executed at least once and thereby ensuring that all reachable code is executed. That is, every branch taken each way, true and false.
Similarly, what is JaCoCo used for? We use the JaCoCo Maven plugin for two purposes: It provides us an access to the JaCoCo runtime agent which records execution coverage data. It creates code coverage reports from the execution data recorded by the JaCoCo runtime agent.
Also know, what is JaCoCo and how it works?
Java Agent. JaCoCo uses class file instrumentation to record execution coverage data. Class files are instrumented on-the-fly using a so called Java agent. This mechanism allows in-memory pre-processing of all class files during class loading independent of the application framework.
How is branch coverage measured?
Notice the two metrics, line coverage and branch coverage. You can see how they are calculated. Take the Cover lines and divide that into the Coverable lines and you get the line coverage percentage. Take the covered branches and divide that into the total branches and you have branch coverage as a percentage.
