 # Mock GraphQL Context Factory Function
+
  In Directory `test/MockContext/*`
 
 ## **Purpose**  
+
 The `createMockGraphQLContext` function provides a **fully mocked GraphQL context** for unit and integration testing of GraphQL resolvers. It ensures that resolvers can be tested **without needing a real database, MinIO storage, or authentication service** and works as centralised mocking mechanism.
 
 ## **Usage**  
 
 ### **Importing the Mock Context**  
+
 ```ts
 import { createMockGraphQLContext } from "test/MockContext/mockGraphQLContext";
 ```

 #### **For an Unauthenticated User**

 `mockContext.currentClient.isAuthenticated` will be `false`.  
 
 #### **For an Authenticated User**

 ```ts
 const mockContext = createMockGraphQLContext(true, "user123");
 ```

 `mockContext.currentClient.user.id` will be `"user123"`.

 ## **Key Benefits**

 **Isolated Testing** – No need for a real database or external services.  
 **Scalable** – Any future changes in `GraphQLContext` can be updated in one place, ensuring a single source of truth.
