PROBLEM:
XUnit TestName property was only returning method name without parameters,
causing all parameterized tests ([Theory] with [InlineData]) to share the
same TestDirectory. This led to catastrophic failures:
- Android: 9+ 'failed to install' errors (directory collision)
- Blazor: 10 'failed to build' errors (corrupted build directories)
- Windows: 1 'failed to build' error (same issue)
ROOT CAUSE:
NUnit's TestContext.CurrentContext.Test.Name includes parameters:
'RunOnAndroid("maui", "net9.0", "Debug")'
XUnit's stack trace reflection only returns method name:
'RunOnAndroid' (same for ALL parameter combinations)
SOLUTION (Option E - Parameter-based identifiers):
1. Added SetTestIdentifier(params object?[] parameters) method
2. Updated all [Theory] test methods to call SetTestIdentifier with params
3. TestName now includes parameters: 'RunOnAndroid_maui_net90_Debug'
4. Falls back to method name + GUID if SetTestIdentifier not called
BENEFITS:
✅ Deterministic - same parameters = same directory across runs
✅ Debuggable - directory names reveal test parameters
✅ Unique - no collision between test cases
✅ Clean - no reflection into XUnit internals
✅ Minimal - one line per test method
FILES MODIFIED:
- BaseBuildTest.cs: Added SetTestIdentifier() and SanitizeTestName()
- AndroidTemplateTests.cs: RunOnAndroid()
- AOTTemplateTest.cs: PublishNativeAOT()
- BlazorTemplateTest.cs: BuildMauiBlazorWebSolution()
- MacTemplateTest.cs: BuildWithCustomBundleResource(), CheckPrivacyManifestForiOS()
- MultiProjectTemplateTest.cs: BuildMultiProject(), BuildMultiProjectSinglePlatform(), VerifyIncludedPlatformsInSln()
- ResizetizerTests.cs: CollectsAssets()
- SampleTests.cs: Build()
- SimpleTemplateTest.cs: Build()
- WindowsTemplateTest.cs: BuildPackaged(), BuildWindowsAppSDKSelfContained(), BuildWindowsRidGraph(), PublishUnpackaged(), PublishPackaged()

Class fixture type 'Microsoft.Maui.IntegrationTests.IntegrationTestFixture' threw in its constructor |
The fixture was throwing IOException when files already existed in extra-packages directory. This occurs because XUnit creates a fixture instance per test class, and multiple test classes can run in parallel or sequentially, causing the second instance to try copying files that the first instance already copied. Fix: Add overwrite: true parameter to File.Copy on line 76 to allow re-copying packages. Co-authored-by: PureWeen <5375137+PureWeen@users.noreply.github.com>

@copilot it looks like we're close Please read these logs and fix |
On Windows, when XUnit runs tests in parallel, multiple IntegrationTestFixture instances are created (one per test class). These fixtures were all trying to delete and recreate the extra-packages directory simultaneously, causing file locking errors: "The process cannot access the file because it is being used by another process." Fix: - Add static lock to ensure only one fixture sets up packages at a time - Add static flag to track setup completion and skip if already done - Only delete/recreate directory if it doesn't exist or is empty - Skip file copy if destination file already exists (avoids locking during concurrent access) This ensures thread-safe initialization while allowing parallel test execution.

Pull request overview
This pull request converts the .NET MAUI integration tests from NUnit to XUnit framework. The conversion involves updating test attributes (TestCase → InlineData, Test → Fact/Theory), assertions (Assert.IsTrue → Assert.True), and test lifecycle management (SetUp/TearDown → Constructor/IDisposable). The PR also introduces collection fixtures for managing device resources (iOS simulator, Android emulator) and updates the Azure DevOps pipeline YAML to use XUnit filter syntax.
Changes:
- Converted test framework from NUnit 3.13.3 to XUnit 2.9.0
- Refactored test lifecycle to use XUnit patterns (constructors, IDisposable, IClassFixture, ICollectionFixture)
- Updated YAML pipeline filters from
Name=toFullyQualifiedName~for XUnit compatibility - Replaced TestContext.WriteLine with Console.WriteLine and ITestOutputHelper
- Added IntegrationTestFixture with file locking protection for Windows parallel execution
- Created collection fixtures for iOS simulator and Android emulator management

The constructor launches the emulator for every test instance. In XUnit, constructors run before each test method execution, which means the emulator will be launched repeatedly for each test. This is inefficient and could cause resource contention. Consider moving emulator launch to the collection fixture (AndroidEmulatorFixture) for one-time setup, or use IAsyncLifetime for proper async initialization if per-test launch is truly needed.

The skip pattern if (true) return; with a comment is unconventional and unclear. XUnit provides built-in skip functionality via Skip property on test attributes or throwing SkipException. This pattern also prevents the test from showing as "Skipped" in test results - it will just appear as "Passed" but exit early. Consider using XUnit's proper skip mechanism, such as checking the condition and throwing new SkipException("reason") from Xunit.Sdk namespace (already imported in Usings.cs).

The skip pattern if (true) return; in the constructor will cause the constructor to exit early, but the test will still be instantiated and executed. In XUnit, skipping tests in constructors doesn't work as expected - the constructor must complete for the test fixture to be properly initialized. If you want to skip all tests in this class when not on macOS, consider using a custom Fact/Theory attribute or checking the condition at the start of each test method and throwing SkipException.

The IOSSimulatorFixture constructor calls TestSimulator.Launch() but doesn't check the return value or handle failure. If the simulator fails to launch, tests will fail with unclear errors later. Consider checking the return value and throwing an exception if launch fails, or logging the failure appropriately.

The test name initialization flow is broken. The constructor accesses TestDirectory which triggers TestName getter, which uses the fallback GUID-based logic and caches the result in _testName. Later when test methods call SetTestIdentifier(), it checks if _testName != null and returns early (line 171-172), meaning the intended parameter-based test name is never set. All tests will use GUID-based names instead of meaningful names derived from test parameters. The early-return guard in SetTestIdentifier should be removed, or the constructor should not access TestDirectory until after SetTestIdentifier has a chance to run.
ITestOutputHelper.WriteLine() is the XUnit best practice for test output because: - Output is associated with the specific test that generated it - Output appears in test results and logs - Better integration with test runners and CI systems Changed BlazorTemplateTest to use _output.WriteLine() instead of Console.WriteLine(). Note: Utility classes (DotnetInternal, XHarness, etc.) still use Console.WriteLine since they are static and don't have access to ITestOutputHelper. This could be improved in future by passing ITestOutputHelper as a parameter to utility methods. Co-authored-by: PureWeen <5375137+PureWeen@users.noreply.github.com>

Examined commits showing .NET 10→11 version bump, SDK updates, integration test provisioning attempts - Identified conditional MAUI pack installation in `eng/Tools.props` with typo "ProivioningMauiPacks" (later fixed by Matt) **Phase 2: Meeting Notes and Requirements Gathering** - User shared meeting action items about fixing integration test pipeline, unit test failures, MAUI workload installation, Helix payload setup - User shared meeting recap discussing SDK mismatch, double install problems, need to use Arcade properly, simplified process with build script - Key insight: Use Arcade to install workloads, then run build script with test configuration **Phase 3: Implementing TestRunnerAdditionalArguments** - User asked how to pass arbitrary arguments through `build.sh` - Discovered Arcade's `TestRunnerAdditionalArguments` property by examining SDK source files - Found official documentation confirming this approach - Updated YAML to use `/p:TestRunnerAdditionalArguments="--filter $(testFilter) --logger trx --results-directory ..."` - Committed and pushed (commit 2ac0d18) **Phase 4: Fixing Missing Checkout** - User reported build 1254934 error about `build.cmd` not being recognized - Root cause: Missing checkout step after user deleted `setup-test-env.yml` template call - Added `checkout: self` with `clean: true` - Committed and pushed **Phase 5: PowerShell Quoting Issues (Multiple Failed Attempts)** - Build 1254995 showed MSB1008 error: "Only one project can be specified" - Shell was splitting `--filter "Category=Build"` into separate arguments - Tried multiple approaches over several commits: - Environment variable instead of command-line property - PowerShell backtick escaping - Array splatting - Two-step variable capture - All attempts failed with same symptom: quotes stripped, arguments split - Problem: PowerShell's `&` call operator + Azure DevOps script task layering **Phase 6: Switch to Native Shell** - User made changes switching from `pwsh:` task to `script:` task - Used Azure DevOps `env:` block to set `TestRunnerAdditionalArguments` at process level - This bypassed PowerShell argument mangling entirely -

`IsUnitTestProject` set when name ends with `.UnitTests` OR `.Tests` ❌ - `Microsoft.Maui.IntegrationTests` ends with `.IntegrationTests` but NOT `.Tests` (dot matters!) - Therefore: `IsIntegrationTestProject=true`, `IsUnitTestProject=false` -
