• JDK 17
• Maven 3.9.5
• Docker or PostgreSQL

This is a Spring Boot application implementing a GraphQL service to handle requests related to books and authors.

The controller provides four queries:

• getBookByName: Returns a book based on the specified name.
• getAllBooks: Retrieves all books present in the repository.
• getAuthorById: Fetches an author based on the provided ID.
• getAllAuthors: Retrieves all authors available in the repository.

Follow the steps to start the application:

• First, clone the repository:

  git clone https://github.com/keploy/samples-java

  Navigate to the project folder:

  cd samples-java/spring-boot-postgres-graphql

• Depending on your OS and preference (Docker/Native), you can set up Keploy using the one-click installation method:

  curl -O https://raw.githubusercontent.com/keploy/keploy/main/keploy.sh && source keploy.sh

If you have Docker installed and prefer a PostgreSQL instance in a container, follow these steps:

1. Build the Docker image:

      docker build -t postgres_library:demo ./postgres_demo_docker

2. Run a container from the generated image:

      docker run -d -p 5432:5432 --name postgres postgres_library:demo

1. Your application is ready to be executed!! To start Keploy in record mode, in the root directory, run:

   keploy record -c "mvn spring-boot:run"

Now, go to localhost:8081/graphiql and access the GraphQL interface to make requests to the application.

• Make a getAllBooks query:

     query {
       getAllBooks {
           name
           author {
              id
              firstName
              lastName
           }
       }
     }

• Make a getBookByName query:

     query {
       getBookByName(name: "The Secret of the Moon") {
           id
           name
           pageCount
           author {
              firstName
              lastName
           }
       }
     }

• Make a getAllAuthors query:

     query {
        getAllAuthors {
           id
           firstName
           lastName 
        }
     }

• Make a getAuthorById query:

     query {
        getAuthorById(id: 2) {
           firstName
        }
     }

You can experiment with the data you want to retrieve from the query by removing or rearranging fields.

The generated tests and mocks are stored in the Keploy directory in the current working directory.

To test the app, start Keploy in test mode. In the root directory, run:

   keploy test -c "mvn spring-boot:run" --delay 15

This will run the tests and generate the report in the Keploy/reports directory in the current working directory.
