Crashes When Creating S3 - Profile default not found

[petermetz]

The code:

  const AWSMock = require('aws-sdk-mock');
  const AWS = require('aws-sdk');
  AWSMock.setSDKInstance(AWS);
  AWS.config.update({ region: 'ap-southeast-2' });
  AWSMock.mock('S3', 'getObject', { 'Body': Buffer.from('somestring') });
  AWSMock.mock('S3', 'putObject', { 'Body': Buffer.from('somestring') });

  const s3Config = { apiVersion: '2006-03-01' };

   // it crashes here
  const s3 = new AWS.S3(s3Config);

The stack trace:

@petermetz please ensure you have the AWS credentials defined for the user. Does creating an S3 object work from your localhost without the mock?

[petermetz]

@nelsonic Ohh! The reason I wanted the mock was because I want my unit tests to run without me having to manage AWS credentials.

Is running without credentials maybe a feature on the road map or would you consider adding it? Thanks for the great library either way.

if anyone interested, way to mock it using only jest

jest.mock('aws-sdk', () => {
  return {
    S3: jest.fn(() => ({
      getObject: jest.fn(() => ({ promise: () => ({ Body: fs.readFileSync('path to file') }) })),
    })),
  };
});
