Statistics

• Types covered: This shows the percentage of types in your schema that have been covered by your tests. In your case, you have achieved 100% coverage for types, which means that all types in your schema have been tested.
• Types covered fully: This shows the percentage of types that have been fully covered by your tests, meaning that all fields in those types have been tested. In your case, you have not achieved 100% coverage for fully covered types, as the percentage is at 0%.
• Fields covered: This shows the percentage of fields in your schema that have been covered by your tests. In your case, you have achieved 50% coverage for fields, which means that only half of the fields in your schema have been tested.
• Total Queries: This shows the total number of queries in your schema that have been tested.
• Total Mutations: This shows the total number of mutations in your schema that have been tested.
• Total Subscriptions: This shows the total number of subscriptions in your schema that have been tested.
