Mocking s3iface

[kkesley]

Hi, I'm trying to mock s3iface, however, some methods with aws.Context seems to be mocked differently. Here's one example:

mock:

// AbortMultipartUploadWithContext mocks base method
func (m *MockS3API) AbortMultipartUploadWithContext(arg0 context.Context, arg1 *s3.AbortMultipartUploadInput, arg2 ...request.Option) (*s3.AbortMultipartUploadOutput, error) {
    m.ctrl.T.Helper()
    varargs := []interface{}{arg0, arg1}
    for _, a := range arg2 {
        varargs = append(varargs, a)
    }
    ret := m.ctrl.Call(m, "AbortMultipartUploadWithContext", varargs...)
    ret0, _ := ret[0].(*s3.AbortMultipartUploadOutput)
    ret1, _ := ret[1].(error)
    return ret0, ret1
}

interface:

AbortMultipartUploadWithContext(aws.Context, *s3.AbortMultipartUploadInput, ...request.Option) (*s3.AbortMultipartUploadOutput, error)

note the difference in the first arg: context.Context vs aws.Context

it results in type error when passing to my function. Is there any resolution to this?

Note: this is how I generated those mocks: mockgen -destination s3iface/mock_s3iface.go github.com/aws/aws-sdk-go/service/s3/s3iface S3API

am having a similar issue with sqsiface:

$ mockgen -source=~/Code/go/src/github.com/aws/aws-sdk-go/service/sqs/sqsiface/interface.go -destination=mockSQS.go

Update: resolved! specify the full path, ~ are not treated correctly

@kkesley the documentation specifies that aws.Context is just an alias to context.Context which is also an interface.

https://docs.aws.amazon.com/sdk-for-go/api/aws/#Context

Do you have repro steps?

I got this error:

cannot use mockS3 (type mock_s3iface.MockS3API) as type s3iface.S3API in field value: mock_s3iface.MockS3API does not implement s3iface.S3API (wrong type for AbortMultipartUploadWithContext method) have AbortMultipartUploadWithContext(context.Context, s3.AbortMultipartUploadInput, ...request.Option) (s3.AbortMultipartUploadOutput, error) want AbortMultipartUploadWithContext(aws.Context, s3.AbortMultipartUploadInput, ...request.Option) (s3.AbortMultipartUploadOutput, error)

However after experimenting with the project, it turns out that the problem is caused by different version of the iface and aws-sdk. Which is not related to the library.

I'm closing this.

Thanks!
