Test error - ERROR: setUpClass (tests.integration.test_s3transfer.TestS3Transfers)

Running the tests on F24 (next Fedora release), this is what I get:

This looks like you are running into the same issue as this one: boto/boto3#498. From the sound of the issue, you may not be setting your credentials correctly. Let me know if this helps you run the tests. We are working to improve the error message as well.

Thanks a lot for the response.
I'm pretty shocked by the fact that to run tests I need to put credentials in it (and I'll not be able to do so, otherwise the whole world will see them).
Is there an option to run only offline tests? Is there a plan to have only offline tests?

[kyleknap]

You only need credentials to run the integration tests. For all most of the projects that we maintain: botocore, boto3, AWS CLI, if a test is in the integration directory then you will most likely need credentials because it will make a request over the wire to the AWS service.

Our offline tests that is comparable to the integration test suite it is the functional test suite. It is pretty much an integration test except we do not send the request over the wire at the very end and we return our own response. These tests do not require credentials for them to pass. For your use case, I would recommend just running the tests in the unit and functional test suites to make sure everything is working. That is the same thing we do for our Travis job for this GitHub repository. For Travis, we just run this script for the tests: https://github.com/boto/s3transfer/blob/develop/scripts/ci/run-tests. Let us know if that helps.

Thanks a lot :) I'll implement what you suggested!
