Use Case

As a Node.js engineer
I want to confirm CSOT prose/spec tests pass on 4.4 replica sets
So that I know CSOT works on this server version

User Experience

• What is the desired/expected outcome for the user once this ticket is implemented?
  • Same as the rest of CSOT, times out TXN/Session operations
• If bug: What is the number of impacted customers? How severe is the impact? Is anyone blocked or broken?
  • Not a bug

Dependencies

• Failpoints, 4.4 replica set

Risks/Unknowns

• What could go wrong while implementing this change? (e.g., performance, inadvertent behavioral changes in adjacent functionality, existing tech debt, etc)
  • No driver changes, test only
• Is there an opportunity for better cross-driver alignment or testing in this area?
  • Potentially, it is unknown why we weren't able to get this server version/topology to respond to the fail point correctly.
• Is there an opportunity to improve existing documentation on this subject?
  • If

Acceptance Criteria

Implementation Requirements

• Make 4.4 replica sets block a connection for long enough to fire a CSOT error

Testing Requirements

• Unskip CSOT session tests on 4.4 replica sets

Documentation Requirements

• None

Follow Up Requirements

• Use investigation to determine if the spec or prose tests need clarification
