Configuring your entity

In order to use this plugin, you must set the backstage.io/code-coverage annotation on entities for which coverage ingestion has been enabled.

metadata:
  annotations:
    backstage.io/code-coverage: enabled

There's a feature to only include files that are in VCS in the coverage report, this is helpful to not count generated files for example. To enable this set the backstage.io/code-coverage annotation to scm-only.

metadata:
  annotations:
    backstage.io/code-coverage: scm-only

Note: It may be required to set the backstage.io/source-location annotation, however this should generally not be needed.
