Description
Summary of Changes
This PR rewrites the integration tests for
node-specific/operation_examples.Notes for Reviewers
I noticed that the entire file seems to be outdated, many tests are repeating test from other, more specific modules (such as aggregations, transactions, etc.), but at the same time I decided against refactoring the entire 4k lines file, focusing only on what's necessary to this project - getting rid of callbacks, and eventually mongodb-legacy wrapper.
Therefore changes contain just 1 test.
What is the motivation for this change?
This work is part of a larger, ongoing initiative to convert all tests to use
async/await, with the ultimate goal of removing the legacy driver wrapper.Double check the following
