Enzyme has lost support in React 17+. As a part of the React 18 upgrade, we need to transition our test suite away from Enzyme and towards react-testing-library.

As a part of the spike, we should figure out:

• How much effort will it take to rewrite all enzyme tests? How many tests are affected?
• Is the Jest upgrade a prerequisite for this process?
• How can we prevent further Enzyme tests from being written in the meantime?

Acceptance Criteria

• A comprehensive audit list of Enzyme tests and their complexity levels.
• Documentation of any identified challenges and suggested solutions.

• Proposed API for shared RTL test utilities.

• A step-by-step migration roadmap for items in the audit list.
