How to mock aws-sdk gem?

Question

I have some code that uploads a file to Amazon S3, using the aws-sdk gem. Apparently it does an HTTP put to upload the file.

Is there a good way to mock thi

Answer 1

If you're using version 2 of the aws-sdk gem try adding:

Aws.config.update(stub_responses: true)

to your RSpec.configure block (usually found in your rails_helper.rb file)

---

While the above works, it will return empty responses if you don't further specify response content - not necessarily valid, but stubbed.

You can generate and return stubbed response data from a named operation:

s3 = Aws::S3::Client.new
s3.stub_data(:list_buckets)
#=> #>

In addition to generating default stubs, you can provide data to apply to the response stub.

s3.stub_data(:list_buckets, buckets:[{name:'aws-sdk'}])
#=> #], owner=#>
