+# Exercise 5
+
+In this exercise, you will configure the existing job to execute tests. Furthermore, you'll enhance the job to process the test results and code coverage metrics.
+
+## Displaying JUnit and JaCoCo Test Results
+
+1. Configure the `gradle-initializr` project to parse the JUnit XML results for unit test. The files can be found in the directory `build/test-results/test`.
+2. Execute the build twice to generate a graph. Have a look at the executed tests in the test results.
+3. Include all test results (unit and integration tests) in the reporting.
+4. Have a look at how the test result trend changes.
+5. Install the JaCoCo plugin.
+6. Reconfigure the Gradle build step to also generate JaCoCo reports: `clean build jacocoTestReport jacocoIntegrationTestReport`.
+7. Add a post-build action for publish the JaCoCo reports. Use the following path to look for results: `build/jacoco/**.exec`.
+8. Execute the build twice to generate a graph. Have a look at the code coverage results.
