Performance test for graphQL API

Question

Today I\'m doing my API automation testing and performance testing with Jmeter when the server is a REST API.

Now the development changed to graphQL API, and I have two

Answer 1

I have recently tried API testing with GraphQl with both GET and POST request in Jmeter

Make sure its POST request for both Query and Mutation

Example Your Graph Ql query

{
  storeConfig{
    default_title
    copyright
  }
}

For Jmeter it would be like this

{
    "query":"{ storeConfig { default_title copyright } }"
}

Step up HTTP Request

In place of the localhost, your domain name will come. Make sure you don't add https

Example:- https://mydomainname.com

In Jmeter :- mydomainname.com

Setup HTTP Header Manager

For requesting Mutation in Jmeter

Example mutation in Graphql

 mutation {
      generateCustomerToken(
          email: "rd@mailinator.com"
          password: "1234567"
      ) {
          token
   }
}

In Jemeter mutation will be like this

{
    "query":"mutation { generateCustomerToken( email: \"rd@mailinator.com\" password: \"1234567\" ) { token } }"
}

Replace double quotes with (\") as shown in above query
