SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides Jest tests for encryption/decryption flows in React Native apps, enabling reliable verification of encrypted data handling, mock storage, and end-to-end integrity.

Core Features & Use Cases

  • Automated encryption roundtrip tests: Verify that encryption and decryption return the original content across scenarios.
  • Mocked storage and crypto modules: Simulate expo-secure-store and crypto behavior for deterministic tests.
  • Edge-case coverage: Test empty strings, Unicode data, large payloads, and tamper-detection logic.

Quick Start

Install dependencies and run npm run test:encryption to execute the Jest suite for encryption flows.

Frequently Asked Questions about test-encryption

FAQPage Schema
How do I test encryption and decryption flows in React Native with Jest?▼

Testing encryption roundtrips in React Native involves running Jest suites that verify encrypted data decrypts back to its original form, checking MAC integrity and edge cases like Unicode data using mocked expo-secure-store and crypto-js.

What do I need to mock when testing expo-secure-store encryption in Jest?▼

To test expo-secure-store encryption in Jest, you need mock modules for both expo-secure-store and expo-crypto to simulate storage and cryptographic behavior, ensuring deterministic test execution for your encrypted data flows.

Does this encryption testing approach cover edge cases like empty strings and large payloads?▼

Yes, encryption testing covers edge cases including empty strings, Unicode data, large payloads, and tamper-detection logic, ensuring your React Native encryption implementation handles diverse data scenarios reliably.

Why does my React Native encryption unit test fail with inconsistent results?▼

Inconsistent encryption test results usually occur when expo-secure-store and expo-crypto are not properly mocked, leading to non-deterministic behavior that deterministic mock modules are designed to eliminate.

Can I use crypto-js with expo-secure-store for encryption tests in React Native?▼

Yes, you can use crypto-js with expo-secure-store for encryption tests in React Native by combining crypto-js for encryption operations with mocked expo-secure-store modules to verify data storage and retrieval flows.
