<GenerationInfo sourceFile="packages/testing/src/simple-graphql-client.ts" sourceLine="39" packageName="@vendure/testing" />

A minimalistic GraphQL client for populating and querying test data.

```ts title="Signature"
class SimpleGraphQLClient {
    constructor(vendureConfig: Required<VendureConfig>, apiUrl: string = '')
    setAuthToken(token: string) => ;
    setChannelToken(token: string | null) => ;
    getAuthToken() => string;
    query(query: DocumentNode | TypedDocumentNode<T, V>, variables?: V, queryParams?: QueryParams) => Promise<T>;
    fetch(url: string, options: RequestInit = {}) => Promise<Response>;
    queryStatus(query: DocumentNode, variables?: V) => Promise<number>;
    asUserWithCredentials(username: string, password: string) => ;
    asSuperAdmin() => ;
    asAnonymousUser() => ;
    fileUploadMutation(options: {
        mutation: DocumentNode;
        filePaths: string[];
        mapVariables: (filePaths: string[]) => any;
        contentTypeOverrides?: { [index: number]: string };
    }) => Promise<any>;
}
```

<div className="members-wrapper">

### setAuthToken

\<MemberInfo kind="method" type={`(token: string) => `}   />

Sets the authToken to be used in each GraphQL request.

### setChannelToken

\<MemberInfo kind="method" type={`(token: string | null) => `}   />

Sets the authToken to be used in each GraphQL request.

### getAuthToken

\<MemberInfo kind="method" type={`() => string`}   />

Returns the authToken currently being used.

### query

\<MemberInfo kind="method" type={`(query: DocumentNode | TypedDocumentNode<T, V>, variables?: V, queryParams?: QueryParams) => Promise<T>`}   />

Performs both query and mutation operations.

### fetch

\<MemberInfo kind="method" type={`(url: string, options: RequestInit = {}) => Promise<Response>`}   />

Performs a raw HTTP request to the given URL, but also includes the authToken & channelToken
headers if they have been set. Useful for testing non-GraphQL endpoints, e.g. for plugins
which make use of REST controllers.

### queryStatus

\<MemberInfo kind="method" type={`(query: DocumentNode, variables?: V) => Promise<number>`}   />

Performs a query or mutation and returns the resulting status code.

### asUserWithCredentials

\<MemberInfo kind="method" type={`(username: string, password: string) => `}   />

Attempts to log in with the specified credentials.

### asSuperAdmin

\<MemberInfo kind="method" type={`() => `}   />

Logs in as the SuperAdmin user.

### asAnonymousUser

\<MemberInfo kind="method" type={`() => `}   />

Logs out so that the client is then treated as an anonymous user.

### fileUploadMutation

\<MemberInfo kind="method" type={`(options: {         mutation: DocumentNode;         filePaths: string[];         mapVariables: (filePaths: string[]) => any;         contentTypeOverrides?: { [index: number]: string };     }) => Promise<any>`}   />

Perform a file upload mutation.

*Example*

```ts
// Testing a custom mutation:
const result = await client.fileUploadMutation({
  mutation: gql`
    mutation AddSellerImages($input: AddSellerImagesInput!) {
      addSellerImages(input: $input) {
        id
        name
      }
    }
  `,
  filePaths: ['./images/profile-picture.jpg', './images/logo.png'],
  mapVariables: () => ({
    name: "George's Pans",
    profilePicture: null,  // corresponds to filePaths[0]
    branding: {
      logo: null  // corresponds to filePaths[1]
    }
  })
});
```
