Introduction
In this blog, you will learn about GraphQL Requests in Ready API. We will know what GraphQL is and how testing is performed in GraphQL.
Ready API is a REST and SOAP API automation tool. It is an integrated suite of applications for API testing. It helps in functional testing, virtualization, and integration. It is an easy-to-use tool for the development team. It makes the process easy and reliable.
What is GraphQL?
GraphQL is a query language. GraphQL language help to fetch the data from the API.
It helps retrieve the data from the API and returns it in JSON format. It returns the data in an easily understandable form to the client.
The client can quickly get the data from the query he has to fetch from the table.
GraphQL Query
{
Users {
name
}
}
The JSON response you get from the above will look like this.
The return response may look in the following JSON object format. The return response does not contain the data that is added. It only returns the id of the user that has been asked in the response.
{ "data": {
addUser: {
"id": 3
}
}
}
🔥Schema
The data that can be retrieved from the service.
GraphQL schema helps to find the information that can be achieved from the service.
It also helps to define the mutations, queries, object types, fields, and attributes.
GraphQL in ReadyAPI
To work with the GraphQL request in ReadyAPI, it is essential to have a ReadyAPI license.
You will require a Ready API pro license to work with the functional test.
GraphQL services help in the interaction of the client with the service and check whether working of the service.
Ready API can interact with GraphQL by sending queries and requests.
When you have GraphQL schema, you can add the GraphQL API to your project. Ready API help in saving this schema to the project and generates the query and mutations described in the schema.
When requests are added to the functional test, you can use the GraphQL mutations for sending the mutation request or GraphQL query for sending the query request.
These queries are linked to the service so that you can validate the response and request against the schema. You can reuse environments and authorization settings.
GraphQL test step is used when you don't have API schema. You can manually configure the query and mutation.
The test does not support the environments, and the functional test cannot inherit authentication settings from the service.
GraphQL Requests
In GraphQL requests, you send the queries and mutations.
To specify with the GraphQL query and mutation, select the request panel and pass the query in the request tab.
The query variables below are used to pass the query parameters.
Property Expansion
Property expansion can be used for queries or mutation and variables.
To insert a property expansion, follow the below steps.
In the request tab at the top panel, right-click on the editor where you want to add the property expansion and select get data.
In the get data option, select the property and click on Add.
ReadyAPI will insert the proper expansion.
Method Change
GraphQL supports two methods get and post. Select the methods by clicking on the drop-down list.
Mutations only support this post method.
Validation in ReadyAPI
ReadyAPI can validate the GraphQL request and response against a schema.
When a GraphQL schema is added to the project, Ready API can generate the query or mutations against this schema.
The query or mutations, even the test steps will have the links attached to the schema.
The Ready API can validate queries or mutations. It can check whether they are correct or not.
Ready API cannot validate the manually added queries and mutations.
Validate Requests and Response🎯
Ready API has the feature to validate the request and response received from the GraphQL schemas.
The request can be validated as follows:
To validate a request, select the validate option beside the Request panel.
This will verify the fields and attributes in the query and check if the type also has the same fields.
Validate Response🎯
For the JSON response, you receive, select the JSON and then select the validate option.
Ready API further checks the validation of the response with the requested field that is passed.

What are some of the languages for API?
API uses several languages. A few of them are Perl, ruby, python, ava, etc.
