XCTest and XCUITest assess iOS code and user flows. Security features requiring physical hardware or a final signed package need additional tests in the appropriate environment.
Evaluation approach
Unit, performance and interface tests answer different questions. Hardware, signing and the test environment can affect security SDK behavior.
Application example
Use interface tests to check that an App Attest failure or RASP warning leaves the user with a safe, understandable flow.
Limits and considerations
A simulator pass does not establish Secure Enclave or production attestation behavior.
Testing iOS security flows
Test local policy functions with small, controlled inputs and evaluate device-dependent services in integration tests. Simulator results cannot replace hardware evidence.
Document differences between test and distribution conditions. Include errors and unavailable-service cases in flows using App Attest, Keychain or biometrics. Define expected results by their effect on the transaction.
Checks and decisions
- Separate test types
- Include physical devices
- Exercise cancellation and failure paths
Interpret XCTest results alongside platform security tests.
