5 Myths About API Mocking (Gently Ruined)
Gently ruining a popular belief.
If it cannot be measured, it is a hobby. Here are five beliefs about mocking that do not survive contact with a real workflow.
Myths, briefly
- Mocks do not hide bugs. Untested states do.
- Mocking in the browser is not just for unit tests.
- Setup is a rule, not a project.
Myth 1: "Mocks hide real bugs"
Mocks hide bugs only if you stop testing against the real API. Use the mock to unblock and to reach states the real API rarely produces; use the real API to confirm the contract. Both, not either.
Myth 2: "Mocking is for unit tests"
Unit-test mocks live in code. Browser-level mocks live in the running app, which makes them useful for exploratory testing, demos and design review, no code changes required.
Myth 3: "It takes ages to set up"
A basic rule is a URL pattern plus a JSON body. If it takes longer than a coffee, the tool is wrong or the response shape is not agreed yet, and the second is the real problem.
Myth 4: "Only developers benefit"
QA reproduces failures on demand. Designers check empty and error states. Sales engineers run demos that never depend on a flaky staging server. The person who benefits most is often not the one who writes the rule.
Myth 5: "Mocks go stale, so why bother"
Stale mocks are a process problem. Keep one shared example per endpoint, date your rules, and delete the ones whose real API has shipped. A five-minute review beats a month of drift.
