Comprehensive Guide to HarmonyOS Application Testing (2025 Edition)

#harmony

I. Test Environment Setup

1. Toolchain Installation

Essential Tools:

DevEco Studio 5.0+ (Integrated testing framework)
DevEco Testing Client (Specialized testing tool)
HDC Command-Line Tool (Device debugging)

Installation Steps:

Check "HarmonyOS SDK" and "Testing Toolkit" during DevEco Studio download
Install DevEco Testing Client (Windows/Mac), ensure antivirus software doesn't block installation
Configure environment variables:

   # Windows example
   setx HDC_PATH "C:\Program Files\DevEco Testing\app\resource\bin"

2. Device Connection Configuration

Real Device Debugging Prep:

Enable Developer Mode: Settings → About Phone → Tap Build Number 7 times
Activate USB Debugging: Settings → System & Updates → Developer Options → Enable "USB Debugging"
Driver Installation: Windows users must manually install device drivers (Download from official site)

Connection Verification:

# List connected devices
hdc list targets
# Sample output:
# [1] 127.0.0.1:5037 (Huawei Mate60 Pro)

II. Core Testing Tools

1. DevEco Testing Suite

Key Features:

Intelligent traversal testing: AI-powered user path simulation
Performance monitoring: Real-time CPU/memory/frame rate collection
Security scanning: Automatic permission abuse detection

Usage Example:

# Create stability test
deveco-test create-stability --app=com.example.app --duration=3600
# Execute distributed capability test
deveco-test run-distributed --scenario=service_migration

Report Interpretation:

Crash Heatmap: Red markers indicate frequent crash points
Memory Leak Curve: Visualize memory allocation trends
Security Risk Matrix: Graded vulnerability assessment

2. HDC Command-Line Interface

Common Commands:

Command	Purpose	Example
hdc app install	Install test package	hdc app install test.hap -r
hdc shell bm clean	Clear cache	hdc shell bm clean -n com.app
hdc logcat	Real-time logging	hdc logcat -v time
hdc screenshot	Capture screen	hdc screenshot /sdcard/1.png

Debugging Tips:

Filter logs: hdc logcat MyTag:D *:S
Monitor memory: hdc shell dumpsys meminfo com.app

3. DevEco Studio Built-in Tools

Performance Analyzer:

Launch via "Profiler" tab
Select monitoring targets: CPU/Memory/Network
Start recording: Click "Record" button

Layout Inspector:

Real-time multi-device preview
Overdraw detection (color-coded)
Component hierarchy visualization

III. Testing Implementation Strategy

1. Unit Testing (SmallTest)

Implementation:

// Sample test case
describe('LoginAbility', () => {
  it('should validate password format', async () => {
    let result = await validatePassword('123');
    expect(result).toBe(false);
  });
});

Coverage Requirements:

Core business logic ≥90%
Public components ≥80%

2. Integration Testing (MediumTest)

Test Scenarios:

Cross-device data synchronization
Service transition success rate
Multi-process communication stress

Toolkit Combination:

DevEco Testing + HDC + XTS Test Suite

3. System Testing (LargeTest)

Test Matrix:

Device Type	Focus Area	Tool Selection
Smartphone	Cold startup	SmartPerf
Tablet	Multi-window	DevEco Studio Layout Inspector
Smart Screen	Large UI interactions	Distributed Scenario Simulator

Automation Script:

# Distributed data sync test
def test_sync():
    device1 = connect_device('127.0.0.1:5037')
    device2 = connect_device('127.0.0.1:5038')
    device1.start_ability('DataService')
    device2.start_ability('DataService')
    assert device1.get_data() == device2.get_data()

Implementation Recommendations:

Adopt layered testing strategy:

   graph TD
   A[Unit Tests] --> B[Integration Tests]
   B --> C[System Tests]
   C --> D[Performance Testing]

Use official toolchain for:

Automated test report generation
Historical performance benchmarking
Test result trend analysis

For complex scenarios, combine:

DevEco Profiler for CPU/memory analysis
SmartPerf for system-level metrics
XTS test suite for compatibility validation

Note: Keep testing artifacts in version control and establish automated CI/CD pipelines for continuous quality assurance.
