What's Changed

• Expand test cases for in the gRPC-Web Trailers test suite to include server-streaming RPCs by @timostamm in Expand test cases for gRPC-Web Trailers to servers-streaming RPCs #935
• Add explicit test cases for errors with metadata by @jhump in Add explicit tests for errors with metadata #970
• Reduce false negatives in Timeouts/** tests by accepting cases where server cancellation is observed before local context cancellation by @jhump in Allow server to cancel when deadline expires #999 and Fix flaky tests: add an interceptor to be smarter about error code attribution #1028
• Remove 'Client Message Size/**' tests since they are not defined correctly by @jhump in Remove 'client message size' tests since they are not defined correctly #1026
• Fix missing 'connect-protocol-version' header in raw requests for Connect protocol test cases by @jhump in Fix missing "connect-protocol-version" header in raw requests for Connect protocol #1027
• Reduce connection load on servers-under-test by caching HTTP client transports by @anuraaga in Cache HTTP client transports #1047
• Reduce false negatives in Server Message Size/** tests by increasing the delay between requests, to accommodate non-deterministic latency between server terminating the RPC with an error and the client trying to send another message on the same stream by @anuraaga in Raise delay for first-request-exceeds-server-limit test #1052

Compatibility

This release includes some changes to test case names. When upgrading, users may need to update configuration for known failing and flaky test cases to work with the new names.

• Test cases in the gRPC-Web Trailers suite have been renamed to include a unary/ prefix. For example, the test case trailers-in-body/expected is now named unary/trailers-in-body/expected.
• The Client Message Size suite (and all test cases therein) has been removed. These cases were not correctly exercising the intended behavior (They may be re-added in the future, after re-formulating them.)

New Contributors
