The power of mocking APIs

on YouTube ↗31m

" summary

A simple weather app is replaced with a Wiremock standalone server on localhost:8080 that returns stubbed responses so the UI can be tested in isolation. Examples: swapped in a thunderstorm JSON, served an invalid JSON that produced NaN and missing sunrise/sunset, injected a 9000 ms fixed delay, and returned a 500 error that crashed the UI. Setup uses a Wiremock dependency and local stub files; source code and mocks are available on GitHub and the approach proves effective for finding bugs early.
