Mutations in GraphQL are similar to queries but they are used to make changes to the data instead of just fetching it.To define a mutation in a GraphQL schema, you need to specify a new type called Mutation in the schema. This type will contain the mutations that can be performed on the data. Each mutation will have a name, input variables (if needed), and a return type.

6 min readTo test GraphQL queries with fragments using Jest, you can define the query with fragments in your test file. You can use tools like Apollo Client or graphql-tag to define and execute the query. In your test, you can mock the response data and test the expected results against the query with fragments. You can also use mock resolvers to simulate server responses and test different scenarios.
