How should deprecation and API changes be handled during testing?

• A. Ignore deprecations.
• B. Replace deprecated APIs with untested alternatives.
• C. Verify that deprecated APIs are removed or updated; ensure no breaking changes to current flows.
• D. Defer to users to adapt.

Answer: (C)

Handling deprecation and API changes in testing centers on validating that deprecated APIs are removed or updated and that existing workflows remain intact. The best practice is to verify that any deprecated API is migrated to the newer, supported path and that there are no breaking changes to the current flows. Tests should exercise the new API paths, ensure behavior stays consistent with what users rely on, and flag any lingering usage of deprecated APIs so cleanup happens before removal. It’s also helpful for tests to check that deprecation warnings are emitted so teams know when to migrate. Ignoring deprecations hides upcoming breakages, using untested replacements risks hidden defects, and leaving migration entirely to users isn’t reliable in a controlled testing process.
