Actual outcome: Queries with fragments in tests do not pass through the fields from the fragment. com/benawad/graphql-typescript-stripe-example/tree/mock-provider----If The MockedProvider component is a mocked version of ApolloProvider that doesn't send network requests to your API. I am working on a Typescript React App and currently use StorybookJS to be able to test my components over different use cases. The MockedProvider component enables you to define mock responses for individual queries that are executed in your test. I'm following the docs provided by Apollo GraphQL for testing React component mutations using MockedProvider. Third query shows loading state but does not return data. Some time ago, we changed the data model for one of our queries, resulting in the following structure for o I was wondering, if there was a way I can provide stub data for development like how we use <MockedProvider> in unit tests and storybook. I am testing a login callback component that calls useQuery with a fairly simple query. Actual outcome: Mock is not returned by The mock that I supplied to the MockedProvider was a different shape than the GraphQL query, so it ended up returning nothing. Actual outcome: MockedProvider only serialises query but not variables pas Intended outcome: Testing code using MockedProvider with a useQuery hook that has a client set useQuery Hook const { loading, error, data, fetchMore } = useQuery<Playlists>(PLAYLISTS, { client Changed import { MockedProvider } from '@apollo/client/testing'; Still we have an error while running jest tests "Invariant Violation: Could not find "client" in the context or passed in as an option. Example with MockedProvider: Did you mean to replace that with your own reproduction URL? Something to keep in mind with mocks and querying is that the mocks are client-specific. I noticed the ID of my variables are getting encoded in the query that's why they don't Debugging and setting up correct mocks with Apollo MockedProvider After React hooks has come into picture, it has become pretty common to use hooks I define a new ApolloMockLink with extended reporting of failed response matches, with diffs, (inspired by priley86’s fork here https://github. It'll allow me to test against a real incomplete @helfer Thanks for the quick response. Code: https://github. It's pretty simple: useDecider: import { useState } from 'react'; import { useQuery, gql } from '@apollo/client'; export I am experiencing an issue with the MockedProvider that I cannot find information for anywhere else. Instead, it allows you to specify the exact response payload for a given By using this MockedProvider component, it's possible to specify the exact results that should be returned for a certain query using the mocks prop. This is useful for inspecting the behavior of errors on initial load The MockedProvider makes the Apollo client available on React’s context.

Please describe. Intended outcome: MockedProvider should successfully match the mock to the query regardless of where fragments are included (${}) in the query. As complexity grows, In this file, we’re going to use React Testing Library to render our component. more The Apollo client library includes a MockedProvider component which allows query and mutation results to be mocked, but didn't offer enough control 13 In my React storybooks, I want to be able to toy around with components that use graphQL queries and mutations (implemented with Apollo). The MockedProvider component is a mocked version of ApolloProvider that doesn't send network requests to your API. My code executes a mutation which that uses a refetch to q I am not sure if this is a bug, or an intentional change (in #5474 ?), but the change in behavior is quite significant and caused our test suite to fail upon upgrading to v3. Variable of third query is set from data returned from first query. When wrapping my component in the MockedProvider, it no longer throws an error that The Apollo client library includes a MockedProvider component which allows query and mutation results to be mocked, but didn't offer enough control within unit tests. I found the issue to my problem. I'm trying to test a component that uses graphql, but when using Apollo's MockProvider I never get the data, it just says loading = true every time. Let's see how to achieve that with MockedProvider. Tests that succeed when they shouldn't are Intended outcome: MockedProvider should serialise query as well as variables passed into it and mock requests accordingly. Instead, it allows you to specify the Learn how to test your React and Apollo code using MockedProvider. Type 'MockedProvider' is missing I have seen a few other posts regarding fetching and MockedProvider. I know the Issue Description It appears that MockedProvider doesn't return the correct values when mocking aliased field names. It creates an Apollo Client instance that resolves operations with mock data instead of Since we don't want to send real requests to a GraphQL API we use MockedProvider from @apollo/react-testing. leonardoanalista changed the title Does MockedProvider behave differently to ApolloProvider?

Lesson: make sure the data you're outputting from the mock matches Intended outcome: MockedProvider should return data for nested nullable fields if response object has a different depth of fields. This works fine using MockedProvider, as Hi ! I came across the following scenario several time when developping unit tests with MockedProvider, and I think some features could make it easier Yes you can, my only problem with MockedProvider was that you couldn't pass addTypename: false to the underlying apollo client, so your mocks would need to include __typename everywhere. MockedProvider expects a list of mocks which corresponds to all the requests I am tryng to use MockedProvider in Typescript but I get the following Error: JSX element type 'MockedProvider' is not a constructor function for JSX elements.

This blog post is here to help! HOWEVER, when it comes time to test, it seems that MockedProvider necessarily returns loading as true, giving no control to the test-writer whether to skip that state (which obviously I would like tot do). Reproduction Render a I want to test a React component that consumes 3 queries by way of HOC. These . Actual outcome: MockedProvider returns undefined if a nullable fie How can GraphQL uploads be mocked with MockedProvider using the apollo-upload-client package? Given the following mutation: mutation import($file: Upload!) { import If MockedProvider is asynchronous and contains one-tick delay, a requirement to delay at least for the same amount of time is reasonable. What it basically does is looks for a specific query, and, when it sees We currently recommend using the MockedProvider and associated API approach to testing applications built using Apollo Client. How to r Warning: An update to ResearchCategoryList inside a test was not wrapped in act(). Most of our tests (there are hundreds of those) rely on the MockedProvider and they used to pass with apollo I would expect MockedProvider to not return this mock because the variables passed in via useQuery are ignored by said query and therefore have no effect. com/priley86/react-apollo/commit I wrote a hook that calls apollo useQuery. 0) tests.
