Question:
I’m trying to stub out a request to get an object in a AWS bucket. I’ve read their docs about stubbing requests and was only able to stub out a bucket, not an object. Here are somethings I’ve tried:
Stubbing through the AWS config:
|
1 2 3 4 5 6 7 8 9 |
Aws.config[:s3] = { stub_responses: { list_buckets: { buckets: [name: "my-bucket"], list_objects: [key: "file.pdf"] } } } |
While that got the bucket, it did not give me the object. Calling s3.buckets would list the bucket, but s3.objects would be empty.
Stubbing through webmock gem:
|
1 2 3 4 |
tempfile = file_fixture('file.pdf').read base_uri = Regexp.new "https://my-bucket.s3.us-west-1.amazonaws. stub_request(:get, base_uri).to_return(status: 200, body: tempfile) |
This still doesn’t seem to work. Calling bucket.objects still returns an empty collection.
The code in my controller I want to test:
|
1 2 3 4 5 6 7 8 |
s3 = Aws::S3::Resource.new bucket = s3.bucket("my-bucket") @files = {} bucket.objects.each do |item| @files[File.basename(item.key)] = item.presigned_url(:get) end |
The goal is I want to make sure my view shows the links to the objects in my @file variable and I want to test that link. Any help would be greatly appreciated! I’m new to developing with AWS S3 and googlge haven’t been much help. I’m using the aws-sdk-s3 gem to work with AWS S3.
Answer:
Figured it out. I also needed to stub out the #list_objects method in order to get the objects. The final stub would look something like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
Aws.config[:s3] = { stub_responses: { list_buckets: { buckets: [name: "my-bucket"] }, list_objects: { contents: [{key: "mykey"}] }, get_object: { body: file_fixture('file').read } } } |
Now if I do s3.buckets.first.objects.first I would get back the stubbed object.
