# Swift test authoring

Test public behavior with deterministic inputs and injected dependencies. For SwiftUI, inspect or
interact through the project's supported test approach; for networking, use a protocol-level test
double and keep request/response synchronization explicit. Avoid sleeps and global state, and keep
fixtures small enough to make failures readable.

Consumer wrappers own test targets, coverage thresholds, view-inspection libraries, and fixture APIs.

Read [network test doubles](references/network-test-doubles.md) for cancellation and shared-state safety.

Read [tautological tests](../test-authoring/references/tautological-tests.md) before finishing any
assertion that is not obviously falsifiable by a defect in the code under test.
