Karma JUnit reporter alert filtering for CI/CD noise reduction

When integrating Karma with the JUnit reporter in a CI/CD pipeline, the volume of XML-generated metadata often leads to notification fatigue. The goal is to configure the environment so that only high-priority failures trigger alerts, while skipped tests or minor warnings do not clutter the build logs.

Currently, using failOnTests: false prevents the CI process from exiting with an error code, but the JUnit reporter still captures all test states in the resulting XML file. This results in CI tools parsing and displaying every skipped case, making it difficult to distinguish between critical regressions and intentional test deactivation.

How can the karma-junit-reporter be configured to exclude specific test statuses like 'skipped' from the XML output? Is there a native configuration property to limit the reporter to only 'failed' events without writing a full custom JavaScript reporter class?
