federation-subgraph-compatibility is a Github Action that allows you to run Apollo Federation Subgraph Specification compatibility tests against your test subgraph implementation. See compatibility testing docs for details on the expected schema and the data sets as well as information about the executed tests.

If action is used on PR workflows, compatibility results can be posted on the PR (requires passing in Github Token to the configuration).
