Add `AwsCredentialFeatures` to Credential Providers #4238

landonxjames · 2025-07-28T19:50:02Z

Motivation and Context

Continuing the work in #4224, adding user-agent feature tracking for Credential Providers.

Description

Added AwsCredentialFeatures properties for each implementor of ProvideCredentials in aws-config.

Testing

Added integration tests for each of the supported Credential Providers. This required exposing some previously pub(crate) utility functions as pub under a test-util feature flag.

Overall looks good. It seems like we made a lot of stuff public or behind a test-util feature to allow testing via sdk/integration-tests. Part of me wonders if we wouldn't be better off making these unit tests in aws-config OR updating our integration tests to assert a specific UA credential feature

e.g.

make_test!(prefer_environment, feature: AwsCredentialFeature::CredentialsEnvVars)

That way we don't have to expose a bunch of test utilities just for this. I'm slightly concerned about having to maintain a bunch of things in test-util because we made them public but open to discussion.

Good point. We should generally place tests in sdk/integration-tests only when tests are something specific about those target services. For instance, the test logic in imds_ua_feature can equally apply to any services, so probably better off having those tests in aws-config and making newly exposed test-utils back to pub(crate) 🤔

Will circle back for the test part, but looks great. Thank you for making this change 👍

…nfig test-utils Move remaining test into S3 tests since that kind of serves as our catch all for random features

landonxjames · 2025-07-29T20:46:15Z

We discussed offline and decided that the best course of action, to avoid exposing new pub test-util functions, is to test the credentials features are added in aws-config and only retain some of the tests that don't need new test-util functionality in integration tests. This work was done in:

63f2134 adding tests to aws-config
eda2912 removing the newly expose test-utils
37276c5 removing the now broken integration tests and moving the remaining ones to the S3 test crate
