This article will focus on E2E testing. E2E tests are conducted by a robot, that is mimicking user's interactions with the app. In my React Native application, I use Detox for testing selected user paths. Detox is a library that lets us prepare Gray Box tests.
Today we are going to add specs (again, we will focus only on the happy paths) for GraphQL queries. But there is one thing about the current implementation of the queries that I don’t like. We have everything defined in one file: `app/graphql/types/query_type.rb`
In the last article we added a few GraphQL mutations to our test application. It is time to create automated tests for each of them. But first things first, we need to set up `RSpec` in order to write better specs.
In this article, I would like to focus on adding GraphQL mutations. We will be working on the test application we created previously in this article. It might be helpful for you to know the structure, models, and types we are using so I encourage you to take a look.
GraphQL is an open source query language created by Facebook. It is a powerful tool that you can use for building your API. It is not a silver bullet but it can definitely help you solve some challenges like getting many resources in a single request.
