Remix - Testing

AChange the global handlers array and rerun setupServer() once

BCall server.close() and server.listen() before each test with new handlers

CUse server.use() with new handlers inside each test to override responses

DMock fetch globally with jest.fn() instead of msw

Step-by-Step Solution

Solution:

Step 1: Understand dynamic mocking in msw
msw allows overriding handlers per test using server.use() without restarting the server.
Step 2: Compare options for best practice
Use server.use() with new handlers inside each test to override responses uses server.use() to add new handlers dynamically; other options restart server or use different mocking tools.
Final Answer:
Use server.use() with new handlers inside each test to override responses -> Option C
Quick Check:
server.use() overrides handlers dynamically [OK]

Quick Trick: Use server.use() inside tests to change mocks on the fly [OK]

Common Mistakes:

MISTAKES

Restarting server unnecessarily each test
Modifying global handlers without reinitializing
Confusing msw with jest fetch mocks
