# Key CI/CD/Jenkins Concepts and their Usage
## 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.

<p>
Publish the JUnit reports by pointing to the exact directory containing the XML files.

After executing the build twice you will see a test result trend graph.

Publish the JUnit reporting by using a wild card.
![Publish All JUnit Results](./images/05-test-execution-and-reporting/publish-all-tests.png)
The trend changes accordingly.

Install the JaCoCo plugin.

Configure JaCoCo reporting.
