import { S3Client, GetObjectCommand } from '@aws-sdk/client-s3';
import { mockClientInstance } from 'aws-sdk-vitest-mock';
const client = new S3Client({});
const s3Mock = mockClientInstance(client);
s3Mock.on(GetObjectCommand).resolves({ Body: 'file contents' });
const result = await client.send(new GetObjectCommand({ Bucket: 'my-bucket', Key: 'file.txt' }));
// result.Body === 'file contents'
Create a mock for a specific AWS SDK client instance.
