DEPRECATION: You should no longer do a function call on backend features when adding them to backends. The support for doing that is deprecated, and you should remove all trailing () parentheses after plugins and modules where you add them to your backend or test backends (e.g. when using startTestBackend).
The background for this is that createBackendPlugin and createBackendModule function now effectively return a BackendFeature rather than a () => BackendFeature. This is part of the cleanup efforts for New Backend System 1.0. In the short run this is non-breaking because the feature type has been given a callback signature that returns itself. But we strongly recommend that you remove all now-redundant calls made to feature objects, because that callback signature will be removed in a future release.
Service factories are still callbacks at this point.
Example change:
await startTestBackend({
features: [
eventsServiceFactory(), // service - stays unchanged
- catalogModuleBitbucketCloudEntityProvider(), // module - remove parentheses
+ catalogModuleBitbucketCloudEntityProvider,
