TestTag

Interface for tagging queries, mutations, and subscriptions to enable mocking during testing and previews.

TestTag provides an alternative to ID-based mocking, which is particularly useful when dealing with automatically generated IDs that may change during configuration changes or recompositions.

Usage example:

// Define a test tag
class MyQueryTestTag : QueryTestTag<String>("my-query")

// Use the test tag with a mocking client
testClient.on(MyQueryTestTag()) { "mocked data" }

// Apply the test tag when getting a query
val query = client.getQuery(queryKey, Marker.testTag(MyQueryTestTag()))

This approach allows for consistent mocking even when queries use auto-generated IDs, ensuring reliable test and preview behavior in UI components.
