|
|
> **Status:** COMPLETED
|
|
> **Last updated:** 2025-08-24 16:30 UTC+09:00
|
|
|
|
**Goal:** Create a Flutter Android app that bundles iperf3 and provides a simple GUI for client-mode network throughput testing.
|
|
|
|
## Completed Tasks
|
|
|
|
### Task 1: Scaffold Flutter project ✅
|
|
- Created project with `flutter create` using org `novoyuuparosk`
|
|
- Package: `com.novoyuuparosk.iperf3gui`
|
|
- Kotlin for Android, Swift for iOS
|
|
- Commit: `5a7c36a`
|
|
|
|
### Task 2: Add dependencies and configure analysis ✅
|
|
- Dependencies: `provider: ^6.1.2`, `path_provider: ^2.1.4`
|
|
- Dev dependencies: `flutter_lints: ^6.0.0`, `flutter_test`
|
|
- Strict analysis options (strict-casts, strict-inference, strict-raw-types)
|
|
- Commit: `815fc48`
|
|
|
|
### Task 3: Domain models ✅
|
|
- `TestConfiguration`: server, port, duration, interval, parallelStreams, validation
|
|
- `Iperf3Result`: rawOutput, exitCode
|
|
- Unit tests for both models (5 tests)
|
|
- Commit: `ef194af`
|
|
|
|
### Task 4: iperf3 binary service ✅
|
|
- `Iperf3Service`: spawns Process with CLI args from TestConfiguration
|
|
- Captures stdout/stderr, returns Iperf3Result
|
|
- Commit: `815fc48`
|
|
|
|
### Task 5: TestRunViewModel ✅
|
|
- State enum: idle, running, completed, error
|
|
- Methods: runTest(), reset()
|
|
- ChangeNotifier for UI updates
|
|
- 4 unit tests
|
|
- Commit: `a6922b6`
|
|
|
|
### Task 6: Main test screen UI ✅
|
|
- TextField for server (default: iperf.es.net)
|
|
- TextField for port (default: 5201)
|
|
- ElevatedButton "GO" with loading indicator
|
|
- Status text indicator
|
|
- Raw output TextField (read-only)
|
|
- Provider integration for state management
|
|
- Commit: `815fc48`

## Verification
|
|
|
|
### Static Analysis
|
|
```
|
|
$ flutter analyze
|
|
No issues found! (ran in 0.4s)
|
|
|
|
$ flutter test
|
|
00:00 +10: All tests passed!
|
|
```
|
|
|
|
### On-Device Test (2025-08-24 10:30 JST)
|
|
- Installed on Sony XQ-AS72 (QV7100JQ52, Android 12/API 31)
|
|
- Tapped GO against iperf.es.net:5201
|
|
- iperf3 v3.21 executed without permission error ✅
|
|
- Raw output displayed in text box ✅
|
|
- Status shows "Test complete" ✅
|
|
- Logcat clean: no iperf3-related errors
|
|
|
|
```
|
|
$ adb logcat -d | grep iperf3
|
|
(no permission errors — binary executed successfully)
|
|
```
|
|
|
|

|
|
- Add settings screen for advanced options (UDP, parallel streams, etc.)
|
|
- Add JSON output support for machine-readable results
|
|
- Add proper splash screen and app icon
