# Run Integration Tests Skill

Build the MAUI product, install local workloads, and run integration tests.

## When to Use

- User asks to "run integration tests"
- User asks to "test templates locally"
- User asks to "validate MAUI build with templates"
- User wants to verify changes don't break template scenarios
- User asks to run specific test categories (WindowsTemplates, Samples, Build, Blazor, etc.)

## Available Test Categories

| Category | Platform | Description |
|----------|----------|-------------|
| `Build` | All | Basic template build tests |
| `WindowsTemplates` | Windows | Windows-specific template scenarios |
| `macOSTemplates` | macOS | macOS-specific scenarios |
| `Blazor` | All | Blazor hybrid templates |
| `MultiProject` | All | Multi-project templates |
| `Samples` | All | Sample project builds |
| `AOT` | macOS | Native AOT compilation |
| `RunOnAndroid` | macOS | Build, install, run on Android emulator |
| `RunOniOS` | macOS | iOS simulator tests |

## Scripts

All scripts are in `.github/skills/run-integration-tests/scripts/`

### Run Integration Tests (Full Workflow)

```powershell
# Run with specific category
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category "WindowsTemplates"

# Run with Release configuration
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category "Samples" -Configuration "Release"

# Run with custom test filter
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -TestFilter "FullyQualifiedName~BuildSample"

# Skip build step (if already built)
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category "Build" -SkipBuild

# macOS: Skip Xcode version check (for version mismatches)
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category "macOSTemplates" -SkipBuild -SkipInstall -SkipXcodeVersionCheck

# Auto-provision SDK if not found (first-time setup)
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category "Build" -AutoProvision
```

## Parameters

| Parameter | Required | Default | Description |
|-----------|----------|---------|-------------|
| `-Category` | No | - | Test category to run (WindowsTemplates, Samples, Build, etc.) |
| `-TestFilter` | No | - | Custom NUnit test filter expression |
| `-Configuration` | No | Debug | Build configuration (Debug/Release) |
| `-SkipBuild` | No | false | Skip build/pack step if already done |
| `-SkipInstall` | No | false | Skip workload installation if already done |
| `-SkipXcodeVersionCheck` | No | false | Skip Xcode version validation (macOS) |
| `-AutoProvision` | No | false | Automatically provision local SDK if not found |
| `-ResultsDirectory` | No | artifacts/integration-tests | Directory for test results |

## Workflow Steps

The script performs these steps:

1. **Build & Pack**: `.\build.cmd -restore -pack -configuration $Configuration`
2. **Install Workloads**: `.dotnet\dotnet build .\src\DotNet\DotNet.csproj -t:Install -c $Configuration`
3. **Extract Version**: Reads MAUI_PACKAGE_VERSION from installed packs
4. **Run Tests**: `.dotnet\dotnet test ... -filter "Category=$Category"`

## Example Usage

```powershell
# Run WindowsTemplates tests
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category "WindowsTemplates"

# Run Samples tests
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category "Samples"

# Run multiple categories
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -TestFilter "Category=Build|Category=Blazor"
```

## Prerequisites

- Windows for WindowsTemplates, macOS for macOSTemplates/RunOniOS/RunOnAndroid
- .NET SDK (version from global.json)
- Sufficient disk space for build artifacts
- Local SDK and workloads must be provisioned first

### Provisioning the Local SDK (Required First Time)

Before running integration tests, you must provision the local .NET SDK and MAUI workloads:

```bash
# Step 1: Restore dotnet tools
dotnet tool restore

# Step 2: Provision local SDK and install workloads (~5 minutes)
dotnet cake --target=dotnet

# Step 3: Install MAUI local workloads
dotnet cake --target=dotnet-local-workloads
```

**Verification:**
```bash
# Check SDK exists
ls .dotnet/dotnet

# Check MAUI SDK version
ls .dotnet/packs/Microsoft.Maui.Sdk
```

> **Note:** The old `./build.sh --target=dotnet` syntax no longer works. Use `dotnet cake` directly.

## Output

- Test results in TRX format at `<ResultsDirectory>/`
- Build logs in `artifacts/` directory
- Console output with test pass/fail summary

## Troubleshooting

| Issue | Solution |
|-------|----------|
| "MAUI_PACKAGE_VERSION was not set" | Ensure build step completed successfully |
| "Local .dotnet SDK not found" | Run `dotnet tool restore && dotnet cake --target=dotnet && dotnet cake --target=dotnet-local-workloads` |
| Template not found | Workload installation may have failed |
| Build failures | Check `artifacts/log/` for detailed build logs |
| "Cannot proceed with locked .dotnet folder" | Kill processes using `.dotnet`: `Get-Process \| Where-Object { $_.Path -like "*\.dotnet\*" } \| ForEach-Object { Stop-Process -Id $_.Id -Force }` |
| Session times out / becomes invalid | Integration tests are long-running (15-60+ min). Run manually in a terminal window instead of via Copilot CLI |
| Tests take too long | Start with `Build` category (fastest), then run others. Use `-SkipBuild -SkipInstall` if workloads are already installed |
| iOS tests fail with "mlaunch exited with 1" | Simulator state issue. Run individual tests instead of the whole category (see below) |
| iOS simulator state errors (code 137/149) | Reset simulator: `xcrun simctl shutdown all && xcrun simctl erase all` or run tests individually |

## Running Manually (Recommended for Long-Running Tests)

Integration tests can take 15-60+ minutes depending on the category. For best results, run directly in a terminal:

```powershell
cd D:\repos\dotnet\maui

# Option 1: Use the skill script
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category "Build" -SkipBuild -SkipInstall

# Option 2: Run dotnet test directly (if workloads already installed)
$env:MAUI_PACKAGE_VERSION = (Get-ChildItem .dotnet\packs\Microsoft.Maui.Sdk -Directory | Sort-Object Name -Descending | Select-Object -First 1).Name
.dotnet\dotnet test src\TestUtils\src\Microsoft.Maui.IntegrationTests --filter "Category=Build"
```

### Running All Categories Sequentially

```powershell
# Windows categories (run on Windows)
$categories = @("Build", "WindowsTemplates", "Blazor", "MultiProject", "Samples")
foreach ($cat in $categories) {
    Write-Host "Running $cat..." -ForegroundColor Cyan
    pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -Category $cat -SkipBuild -SkipInstall
}
```

### Running Individual iOS Tests (Recommended)

Running all iOS tests together (`-Category "RunOniOS"`) can cause simulator state issues. For better reliability, run tests individually:

```powershell
# Available iOS tests
$iosTests = @(
    "RunOniOS_MauiDebug",
    "RunOniOS_MauiRelease",
    "RunOniOS_MauiReleaseTrimFull",
    "RunOniOS_BlazorDebug",
    "RunOniOS_BlazorRelease",
    "RunOniOS_MauiNativeAOT"
)

# Run a specific iOS test
pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -TestFilter "FullyQualifiedName~RunOniOS_MauiDebug" -SkipBuild -SkipInstall -SkipXcodeVersionCheck

# Run all iOS tests individually (more reliable than running category)
foreach ($test in $iosTests) {
    Write-Host "Running $test..." -ForegroundColor Cyan
    pwsh .github/skills/run-integration-tests/scripts/Run-IntegrationTests.ps1 -TestFilter "FullyQualifiedName~$test" -SkipBuild -SkipInstall -SkipXcodeVersionCheck
}
```
