Match KotlinConf-app's filesystem layout where every entry point (android, ios, web, shared, ui-components) lives under app/. iosApp is still an Xcode project, not a Gradle module, so settings.gradle.kts is unchanged.

A minimal Kotlin Multiplatform personal-ledger app: login with demo
|
|
credentials, create accounts, add credits and debits. Shared UI across
|
|
Android and iOS via Compose Multiplatform. Doubles as the example
|
|
sanderling runs its property-based specs against.
|
|
|
|
## Stack
|
|
|
|
- Kotlin Multiplatform + Compose Multiplatform (shared UI)
|
|
- SQLDelight for the data layer (unified across platforms)
|
|
- kotlinx.coroutines for state flows
|
|
- kotlinx.serialization for `@Serializable` route types
|
|
|
|
## Prerequisites
|
|
|
|
- `just`
|
|
- JDK 17
|
|
- Android SDK (auto-discovered under `$ANDROID_HOME`, `~/Library/Android/sdk`,
|
|
or the Homebrew cask)
|
|
- Xcode 16+ and `xcodegen` (`brew install xcodegen`) for iOS
|
|
|
|
## Android
|
|
|
|
```sh
|
|
just install # build + install on a booted emulator / device
|
|
just uninstall
|
|
just clean
|
|
```
|
|
|
|
## iOS
|
|
|
|
```sh
|
|
just ios # default device: iPhone 17 Pro
|
|
IOS_DEVICE="iPhone 15" just ios # pick a different simulator
|
|
```
|
|
|
|
`just ios` regenerates `app/iosApp/iosApp.xcodeproj` from `app/iosApp/project.yml`,
|
|
builds the KMP framework (`Shared.framework` from `:app:shared`), links it
|
|
into the SwiftUI host, installs, and launches.
|
|
|
|
## Demo credentials

|
|
|

```
|
|
|
|
## Run a sanderling test (Android)
|
|
|
|
```sh
|
|
just test
|
|
```
|
|
|
|
If no device is connected, sanderling boots the single AVD it finds. With multiple
|
|
AVDs, pick one:
|
|
|
|
```sh
|
|
AVD=Pixel_7 just test
|
|
```
|
|
|
|
Persistent settings can live in `.env` alongside the justfile:
|
|
|
|
```
|
|
AVD=Pixel_7
|
|
DURATION=5m
|
|
```
|
|
|
|
Traces land in `./sanderling/runs/<timestamp>/`.
|
|
|
|
## How it connects to sanderling
|
|
|
|
- Each screen sets a stable Compose `testTag` (`HomeScreen`, `AccountCard`,
|
|
`LedgerRow`, `TxnAmount`, ...). The Sanderling SDK resolves `testTag` to
|
|
`resource-id` on Android and `accessibilityIdentifier` on iOS.
|
|
- Identity for list items is the visible text content (account name; txn
|
|
note + amount). No synthetic IDs encoded in semantics.
|
|
- `contentDescription` is reserved for real accessibility labels, never as a
|
|
data carrier.
|
|
- `sanderling/spec.ts` imports `@sanderling/spec`, reads state via `s.ax.*`,
|
|
asserts properties, and weights the actions the fuzzer picks from.
|
|
- `just test` invokes `sanderling test` against the installed APK.
