From e34ed5282acb74bcd65441dbd0ffe10cd692940f Mon Sep 17 00:00:00 2001 From: Sergei Date: Sat, 31 Jan 2026 15:50:54 -0800 Subject: [PATCH] Add comprehensive BLE integration tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented integration tests for BLE functionality covering: - Connection flow state machine (connecting, discovering, ready) - Event system (listeners, state changes, connection events) - WiFi operations (scan, configure, status, reboot) - Error handling (timeouts, disconnections, concurrent connections) - Batch operations (multiple device connections, cleanup) - State machine edge cases (device name, timestamps) Tests cover both RealBLEManager and MockBLEManager to ensure consistent behavior across real devices and simulator. Updated Jest configuration: - Added expo winter runtime mocks - Added structuredClone polyfill - Added React Native module mocks (Platform, PermissionsAndroid, Linking, Alert) - Updated transform ignore patterns for BLE modules All 36 tests passing with comprehensive coverage of BLE integration. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- jest.config.js | 9 +- jest.setup.js | 59 +++ .../__tests__/BLEManager.integration.test.ts | 488 ++++++++++++++++++ 3 files changed, 555 insertions(+), 1 deletion(-) create mode 100644 services/ble/__tests__/BLEManager.integration.test.ts diff --git a/jest.config.js b/jest.config.js index 4af02ca..389e21d 100644 --- a/jest.config.js +++ b/jest.config.js @@ -3,7 +3,7 @@ module.exports = { testEnvironment: 'node', setupFilesAfterEnv: ['/jest.setup.js'], transformIgnorePatterns: [ - 'node_modules/(?!(expo|expo-router|expo-font|expo-asset|expo-constants|expo-modules-core|@expo/.*|@expo-google-fonts/.*|@react-native|react-native|@react-navigation|react-navigation|@unimodules/.*|unimodules|sentry-expo|native-base|react-native-svg)/)', + 'node_modules/(?!(expo|expo-router|expo-font|expo-asset|expo-constants|expo-modules-core|@expo/.*|@expo-google-fonts/.*|@react-native|react-native|@react-navigation|react-navigation|@unimodules/.*|unimodules|sentry-expo|native-base|react-native-svg|react-native-ble-plx|react-native-base64)/)', ], moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx'], moduleNameMapper: { @@ -17,4 +17,11 @@ module.exports = { '!**/*.d.ts', '!**/node_modules/**', ], + globals: { + 'ts-jest': { + tsconfig: { + jsx: 'react', + }, + }, + }, };
