+# PrettyScreenSHOT Tests
+
+This directory contains unit tests for the PrettyScreenSHOT application.
+
+## Test Framework
+
+- **xUnit** - Modern, extensible unit testing framework for .NET
+- **Moq** - Mocking library for .NET
+- **coverlet** - Code coverage tool
+
+## Running Tests
+
+### Command Line
+
+```bash
+# Run all tests
+dotnet test
+
+# Run tests with verbose output
+dotnet test --logger "console;verbosity=detailed"
+
+# Run tests with code coverage
+dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=opencover
+
+# Run specific test class
+dotnet test --filter "FullyQualifiedName~SettingsManagerTests"
+
+# Run specific test method
+dotnet test --filter "FullyQualifiedName~SettingsManagerTests.Instance_ShouldNotBeNull"
+```
+
+### Visual Studio
+
+1. Open Test Explorer (Test > Test Explorer)
+2. Click "Run All" to run all tests
+3. Right-click individual tests to run or debug
+
+### Visual Studio Code
+
+1. Install "C# Dev Kit" extension
+2. Tests will appear in the Test Explorer sidebar
+3. Click the play button to run tests
+
+## Test Structure
+
+```
+Tests/
+├── Services/
+│   ├── SettingsManagerTests.cs      # Tests for settings management
+│   └── SecurityManagerTests.cs      # Tests for encryption & security
+├── Helpers/
+│   └── DebugHelperTests.cs          # Tests for debug utilities
+└── README.md                         # This file
+```
+
+## Test Coverage
+
+Current test coverage focuses on:
+
+1. **SettingsManager** - Configuration persistence and retrieval
+2. **SecurityManager** - Encryption key generation and derivation
+3. **DebugHelper** - Debug logging utilities
+
+### Expanding Test Coverage
+
+To improve test coverage, consider adding tests for:
+
+- [ ] Screenshot capture functionality
+- [ ] Image processing and editing
+- [ ] Cloud upload providers
+- [ ] Video capture manager
+- [ ] Update system
+- [ ] Localization helpers
+
+## Writing New Tests
+
+### Example Test
+
+```csharp
+using Xunit;
+using PrettyScreenSHOT.Services;
+
+namespace PrettyScreenSHOT.Tests.Services
+{
+    public class YourServiceTests
+    {
+        [Fact]
+        public void YourMethod_WithValidInput_ShouldReturnExpectedResult()
+        {
+            // Arrange
+            var service = new YourService();
+            var input = "test";
+
+            // Act
+            var result = service.YourMethod(input);
+
+            // Assert
+            Assert.NotNull(result);
+            Assert.Equal("expected", result);
+        }
+
+        [Theory]
+        [InlineData("input1", "output1")]
+        [InlineData("input2", "output2")]
+        public void YourMethod_WithMultipleInputs_ShouldReturnCorrectOutputs(
+            string input, string expected)
+        {
+            // Arrange
+            var service = new YourService();
+
+            // Act
+            var result = service.YourMethod(input);
+
+            // Assert
+            Assert.Equal(expected, result);
+        }
+    }
+}
+```
+
+## Best Practices
+
+1. **AAA Pattern** - Arrange, Act, Assert
+2. **Descriptive Names** - Test names should describe what they test
+3. **One Assert Per Test** - Keep tests focused
+4. **Independent Tests** - Tests should not depend on each other
+5. **Fast Tests** - Unit tests should run quickly
+6. **Cleanup** - Restore state after tests (especially with singletons)
+
+## Known Limitations
+
+### Singleton Testing
+
+Some classes (like `SettingsManager`) use the Singleton pattern, which makes testing challenging:
+
+- Tests share state through the singleton instance
+- Tests include cleanup code to restore original values
+- Consider refactoring to use Dependency Injection for better testability
+
+### UI Testing
+
+Current tests focus on business logic and services. UI testing for WPF windows requires:
+
+- UI automation frameworks (e.g., FlaUI, WinAppDriver)
+- Additional setup and configuration
+- Longer test execution times
+
+## Continuous Integration
+
+Tests are automatically run on:
+
+- Every push to any branch
+- Every pull request
+- Scheduled nightly builds
+
+See `.github/workflows/dotnet.yml` for CI/CD configuration.
+
+## Code Coverage Reports
+
+Code coverage reports are generated during CI builds and can be viewed:
+
+- Locally: After running with coverage, check `coverage.opencover.xml`
+- CI: Coverage reports are uploaded as build artifacts
+
+## Troubleshooting
+
+### Tests fail with "dotnet not found"
+
+Ensure .NET 10.0 SDK is installed:
+```bash
+dotnet --version
+```
+
+### Tests fail due to missing dependencies
+
+Restore NuGet packages:
+```bash
+dotnet restore
+```
+
+### Tests fail in CI but pass locally
+
+- Check for environment-specific dependencies
+- Ensure tests don't rely on local file paths
+- Verify tests are platform-independent
+
+## Contributing
+
+When adding new features:
+
+1. Write tests for new functionality
+2. Ensure all tests pass locally
+3. Aim for >70% code coverage
+4. Update this README if adding new test categories

+# Versioning Scheme
+
+PrettyScreenSHOT uses a custom semantic versioning scheme optimized for continuous integration and deployment.
+
+## Version Format
+
+The version follows the format: **MAJOR.MINOR.PATCH**
+
+However, we use specific values for each component to indicate the type of build:
+
+### 🔹 Development Builds: `0.0.X`
+
+**Format:** `0.0.<BUILD_NUMBER>`
+
+- **Purpose:** Continuous integration builds from every commit
+- **Build Number:** Automatically incremented by CI/CD (GitHub Actions run number)
+- **Examples:** `0.0.1`, `0.0.2`, `0.0.42`, `0.0.150`
+- **Trigger:** Automatic on every push to branches
+- **Artifacts:** Available as CI build artifacts
+
+**Usage:**
+```bash
+# These are created automatically by CI/CD
+# No manual tagging required
+```
+
+---
+
+### 🔸 Pre-release/Beta: `0.X.0`
+
+**Format:** `0.<RELEASE_NUMBER>.0`
+
+- **Purpose:** Beta releases and pre-release versions for testing
+- **Release Number:** Manually incremented for each beta release
+- **Examples:** `0.1.0`, `0.2.0`, `0.5.0`
+- **Trigger:** Git tag with format `v0.X.0`
+- **Artifacts:** GitHub Release (marked as pre-release)
+
+**Usage:**
+```bash
+# Create a beta release
+git tag v0.1.0
+git push origin v0.1.0
+
+# The workflow will:
+# - Build the release
+# - Create ZIP archives
+# - Generate checksums
+# - Create GitHub Release (pre-release)
+```
+
+---
+
+### 🔶 Production Release: `X.0.0`
+
+**Format:** `<MAJOR_VERSION>.0.0`
+
+- **Purpose:** Stable production releases
+- **Major Version:** Incremented for major releases (1.0.0, 2.0.0, 3.0.0, etc.)
+- **Examples:** `1.0.0`, `2.0.0`, `3.0.0`
+- **Trigger:** Git tag with format `vX.0.0`
+- **Artifacts:** GitHub Release (full release)
+
+**Usage:**
+```bash
+# Create a production release
+git tag v1.0.0
+git push origin v1.0.0
+
+# The workflow will:
+# - Build the release
+# - Create ZIP archives
+# - Generate checksums
+# - Create GitHub Release (production)
+```
+
+---
+
+## Version Determination
+
+The CI/CD pipeline automatically determines the version type:
+
+| Pattern | Type | Pre-release | Example |
+|---------|------|-------------|---------|
+| `X.0.0` (X ≥ 1) | Production | ❌ No | `1.0.0`, `2.0.0` |
+| `0.X.0` (X ≥ 1) | Beta/Pre-release | ✅ Yes | `0.1.0`, `0.2.0` |
+| `0.0.X` | Development | ✅ Yes | `0.0.42`, `0.0.100` |
+
+---
+
+## Implementation Details
+
+### Project File (`.csproj`)
+
+The base version in the project file is set to `0.0.0`:
+
+```xml
+<AssemblyVersion>0.0.0</AssemblyVersion>
+<FileVersion>0.0.0</FileVersion>
+<Version>0.0.0</Version>
+```
+
+This is overridden at build time by the CI/CD pipeline.
+
+### GitHub Actions
+
+#### Development Builds (`.github/workflows/dotnet.yml`)
+
+```yaml
+- name: Set development build version
+  run: |
+    $buildNumber = "${{ github.run_number }}"
+    $version = "0.0.$buildNumber"
+    echo "BUILD_VERSION=$version" >> $env:GITHUB_ENV
+
+- name: Build solution
+  run: dotnet build /p:Version=${{ env.BUILD_VERSION }}
+```
+
+#### Release Builds (`.github/workflows/release.yml`)
+
+```yaml
+- name: Extract and validate version
+  run: |
+    $version = "${{ github.ref_name }}".TrimStart('v')
+    # Automatically determines if production, beta, or dev
+```
+
+---
+
+## Examples
+
+### Timeline Example
+
+```
+0.0.1  ← First development build
+0.0.2  ← Second development build
+...
+0.0.42 ← 42nd development build
+0.1.0  ← First beta release
+0.0.43 ← Development continues...
+0.0.50 ← More development
+0.2.0  ← Second beta release
+0.0.51 ← Development continues...
+1.0.0  ← First production release! 🎉
+1.0.1  ← Patch release (if needed)
+0.0.52 ← Development for next version
+2.0.0  ← Second major release
+```
+
+### Creating Releases
+
+```bash
+# Development builds - automatic, no action needed
+# Every push triggers a 0.0.X build
+
+# Beta release
+git tag v0.1.0 -m "First beta release"
+git push origin v0.1.0
+
+# Production release
+git tag v1.0.0 -m "First production release"
+git push origin v1.0.0
+```
+
+---
+
+## Rationale
+
+This versioning scheme provides:
+
+1. **Clear Build Tracking** - Every CI build has a unique version
+2. **Automatic Versioning** - No manual intervention for dev builds
+3. **Pre-release Identification** - Clear distinction between beta and production
+4. **Semantic Meaning** - Version number indicates release type at a glance
+5. **CI/CD Integration** - Works seamlessly with GitHub Actions
+
+---
+
+## Migration from Previous Versions
+
+If upgrading from an older versioning scheme:
+
+1. **Current version `0.0.1`** becomes the starting point
+2. Next development build will be `0.0.<NEXT_BUILD_NUMBER>`
+3. First beta release should be `0.1.0`
+4. First production release should be `1.0.0`
+
+---
+
+## FAQs
+
+### Q: Why not standard semantic versioning (1.2.3)?
+
+**A:** Standard semver doesn't clearly distinguish between development builds, beta releases, and production releases. Our scheme makes this distinction explicit and automatic.
+
+### Q: What if I need a patch release?
+
+**A:** For production releases, use standard semver: `1.0.1`, `1.0.2`, etc. The pipeline will detect this as a custom version.
+
+### Q: Can I use alpha or rc tags?
+
+**A:** Yes! For tags like `v0.1.0-alpha` or `v1.0.0-rc1`, the pipeline will automatically mark them as pre-releases.
+
+### Q: How do I know what version I'm running?
+
+**A:** Check the executable properties or use `--version` flag (if implemented). The version is embedded during build.
