API Testing

Hoppscotch’s GraphQL API platform provides you with the best experience to test and play around with GraphQL.

It’s primarily divided into two sections along with other features to help you build and test queries.

​

Request

The request section houses the feature to enter your server endpoint and initiate a connection.

Once the connection is made, the query builder assists you in designing queries to fetch the data that you require and run it.

You can also add dynamic behavior to your queries by defining variables, headers, and authorization.

​

Response

This is where you see the responses to your API endpoints. You can download and copy the returned responses for further use.

​

Schema

GraphQL is a query language for APIs that queries the server and provides the client only the data that is requested by the client. GraphQL enables you to fetch data from multiple APIs in a single query thus helping you build better-performing applications.

GraphQL server uses a GraphQL Schema to describe the structure of your data. Given below is an example of a GraphQL Schema.

type Laptop {
  model: String
  maker: Maker
}

type Maker {
  name: String
  laptops: [Laptop]
}

The above schema defines two types Laptop and Maker. The Laptop type has two fields model and maker. The Maker type has two fields name and laptops. The laptops field in the Maker type is an array of the Laptop type.

GraphQL queries are written in the GraphQL query language. Given below is an example of a GraphQL query.

query {
  maker(name: "Apple") {
    name
    laptops {
      model
    }
  }
}

The above query fetches the name and laptops of the Maker with the name Apple.

GraphQL queries can be executed using a GraphQL client. Hoppscotch has a built-in GraphQL client that can be used to execute GraphQL queries.
