Mocking Apollo GraphQL Queries in React Testing

Learn how to test a component that uses Apollo GraphQL Queries in React Testing. Using the MockedProvider from the @apollo/client/testing library to wrap our component in the test. Providing mocks that exactly match the query you’re trying to mock

When testing our frontend code, we might find ourselves needing to mock GraphQL query responses. Here's how to do it.

When I learn a new technology, the first thing I think is “okay, how do I use this?” But soon thereafter, the question becomes “how do I test this?”

That was the case recently with Apollo GraphQL in my React project. In this post, we’ll learn how to test a component that uses a GraphQL query.

TLDR: There are Two Keys to Getting this Right

The TLDR is that there are two keys to getting this right:

1. Using the MockedProvider from the @apollo/client/testing library to wrap our component in the test
2. Providing mocks that exactly match the query you’re trying to mock

In this video, we re-factor our first React video application code and implement Apollo hooks so that we retrieve data from our GraphQL end-point. There's a lot of re-factoring in this video but it's really worth doing as it makes our React code most testable, and much easier to develop.

GraphQL Data Fetching with Apollo Client in React. Fetching Data using GraphQL Queries with React and Apollo. How to fetch and display data from a GraphQL API in a React project using the Apollo Client state-management library. Before we start getting fully into the Apollo Client, let’s start by creating a React project.

In this video I will teach you guys how to use React as the client for your GraphQL Project. We will be using Apollo Client 3 to handle all the graphql requests to our Apollo server.

A tutorial on using Apollo to consume a GraphQL API from React. You will create a small React application that uses Apollo Client to query a GraphQL API that contains the data for SpaceX’s launches. To secure the application you will use Okta’s okta-react library to make setting up your authentication easy.
