Summary

The CSOT specifications for tailable awaitData cursors specifies the following:

Drivers MUST error if this option is set, timeoutMS is set to a non-zero value, and maxAwaitTimeMS is greater than or equal to timeoutMS

Currently the tailable-awaitData unified spec tests attempt to validate this behavior:

• error if maxAwaitTimeMS is greater than timeoutMS
• error if maxAwaitTimeMS is equal to timeoutMS

However, these tests only verify the occurrence of a client-side error, which may include a client-side timeout. For instance, the Go Driver does not perform the specific validation but rather produces an error due to a client-side timeout.

Acceptance Criteria

The unified spec tests for tailableAwait data cursor should verify that when maxAwaitTime >= timeoutMS the error is not a timeout error. Additionally, more tests should be added for other collection helpers that can construct a tailable awaitData cursors: collection.Watch() and collection.Aggregate().
