CODE COVERAGE WITH JACOCO

--------------------------------------------------------------------------

Measuring code coverage with the Java Code Coverage Library (JaCoCo).

--------------------------------------------------------------------------

**JaCoCo plugin added to pom.xml file:**

```

    

        org.jacoco

        jacoco-maven-plugin

        0.8.5

        

            

                com/example/demo/CodeCoverageWith*

                com/example/demo/configuration/*

                com/example/demo/dto/*

                com/example/demo/dto/response/*

                com/example/demo/model/*

                com/example/demo/repository/*

            

        

        

            

                

                    prepare-agent

                

            

            

            

                report

                test

                

                    report

                

                

                    target/jacoco-report

                

            

        

    

```

**Some packages were exluded from JaCoCo:**

```

    

        com/example/demo/CodeCoverageWith*

        com/example/demo/configuration/*

        com/example/demo/dto/*

        com/example/demo/dto/response/*

        com/example/demo/model/*

        com/example/demo/repository/*

    

```

**Location where the report will be generated:**

```

    

        target/jacoco-report

    

```

--------------------------------------------------------------------------

**After JaCoco plugin is added, the test maven phase is executed:**

**A report is generated in the directory target/jacoco-report:**

![](./screenshots/jacoco_report_directory.png)

**Right now, there are no tests available and the JaCoCo report says there is a code coverage of 7% 

for missed instructions and 0% for missed branches:**

![Report1](./screenshots/jacoco_report_1.png)

**A few unit tests were added and now the code coverage has reached 97% for missed instructions 

and 83% for missed branches:**
