Using with DynamoDB

1. First, install

• npm
• Yarn

yarn add --dev @shelf/jest-dynamodb

1. Specify preset in your Jest configuration:

1. Create jest-dynamodb-config.js and define DynamoDB tables

module.exports = {
  tables: [
    {
      KeySchema: [{AttributeName: 'id', KeyType: 'HASH'}],
      ProvisionedThroughput: {ReadCapacityUnits: 1, WriteCapacityUnits: 1},
    },
    // etc
  ],
};

1. Configure DynamoDB client

1. Write tests

it('should insert item into table', async () => {
    .promise();
  const {Item} = await ddb.get({TableName: 'files', Key: {id: '1'}}).promise();
  expect(Item).toEqual({
    id: '1',
    hello: 'world',
});
