Description

The coverage of the redis instrumentation doesn't meet the expected 85% as calculated by simplecov.

We should add additional test cases so that this gem is being adequately test after every change. Once the coverage meets the required level the coverage override defined in the github Workflow needs to be removed.

Contributor guide

Research direction
Examine the existing redis instrumentation test files and run simplecov to identify uncovered lines. Then write additional test cases to cover those paths.
