I made some features based on my project requirements — see if you can use them.

+
+用于简化 .NET 源生成器测试的测试辅助方法和扩展方法。

+
+## 测试一个源生成器
+
+```csharp
+var result = SourceGenerator.Run<YourSourceGenerator>("要测试的代码");
+```
+
+## 测试一个增量源生成器
+
+```csharp
+var result = IncrementalGenerator.Run<YourSourceGenerator>("要测试的代码");
+```
+
+## 添加.NET环境和依赖
+
+```csharp
+    var references = new List<MetadataReference>();
+
+    // 添加 .NET 10 所有程序集（ReferenceAssemblies.Net.Net100）
+    ImmutableArray<MetadataReference> defaultReferences = ReferenceAssemblies.Net.Net100.ResolveAsync(null, default)。Result;
+    references.AddRange(defaultReferences);
+
+    //添加依赖
+    references.Add(MetadataReference.CreateFromFile(
+        Path.Combine("D:","C#", "Lib", "Debug", "net10.0", "XXX.dll")));
+
+    var result = IncrementalGenerator.Run<YourSourceGenerator>("要测试的代码", null, references);
+```
+
+## 获取创建的源生成器/增量源生成器
+```csharp
+    var result = IncrementalGenerator.Run(sourceCode, out YourSourceGenerator generator, null, references);
+```
+```csharp
+    var result = SourceGenerator.Run(sourceCode, out YourSourceGenerator generator, null, references);
+```
+## 获取生成的源代码
+
+### 获取所有生成的源代码
+
+```csharp
+var generatedSources =  result.GetSources();
+```
+
+### 获取特定文件的源代码
+
+```csharp
+var generatedSource =  result.GetSource("TestId.g.cs");
+```
+
+### 对比生成的源代码与期望的源代码
+
+你可以对比生成的源代码与期望的源代码之间的差异。结果包含一个bool值 hasDifferences 以及按行区分的差异列表 differences。
+
+```csharp
+var (hasDifferences, differences) = Diff.Compare(generatedSource, expectedSource);
+```
+
+## 进行验证
+
+### 使用断言
+
+借助下面其中一个测试框架包，你还可以断言生成的源代码与期望源的代码之间的差异。

+[![XUnit](https://img.shields.io/nuget/dt/SourceGeneratorTestHelpers.XUnit?label=XUnit)](https://www.nuget.org/packages/SourceGeneratorTestHelpers.XUnit)
+[![NUnit](https://img.shields.io/nuget/dt/SourceGeneratorTestHelpers.NUnit?label=NUnit)](https://www.nuget.org/packages/SourceGeneratorTestHelpers.NUnit)
+[![MSTest](https://img.shields.io/nuget/dt/SourceGeneratorTestHelpers.MSTest?label=MSTest)](https://www.nuget.org/packages/SourceGeneratorTestHelpers.MSTest)
+
+```csharp
+var result = IncrementalGenerator.Run<YourSourceGenerator>("要测试的代码");
+
+result.ShouldProduce("TestId.g.cs", "预期的代码");
+```
+
+_注意：如果你不想断言源生成器运行期间的诊断错误，可以像下面这样直接禁用。_
+
+```csharp
+var result = IncrementalGenerator.Run<YourSourceGenerator>("要测试的代码");
+
+result.ShouldProduce("TestId.g.cs", "预期的代码", false);
+```
+
+### 使用Verify
+
+内置了对 [Verify](https://github.com/VerifyTests/Verify) 的支持，通过 VerifyAsync 方法实现。 
+
+#### XUnit
+
+```cs
+public class SourceGeneratorTests
+{
+    [Fact]
+    public Task ShouldProductTestId()
+    {
+        var result = IncrementalGenerator.Run<YourSourceGenerator>("要测试的代码");
+        return result.VerifyAsync("TestId.g.cs");
+    }
+}
+```
+
+#### NUnit
+
+```cs
+[TestFixture]
+public class SourceGeneratorTests
+{
+    [Test]
+    public Task ShouldProductTestId()
+    {
+        var result = IncrementalGenerator.Run<YourSourceGenerator>("要测试的代码");
+        return result.VerifyAsync("TestId.g.cs");
+    }
+}
+```
+
+#### MSTest
+
+```cs
+[TestClass]
+public class SourceGeneratorTests :
+    GeneratorDriverTestBase
+{
+    [TestMethod]
+    public Task ShouldProductTestId()
+    {
+        var result = IncrementalGenerator.Run<YourSourceGenerator>("要测试的代码");
+        return VerifyAsync("TestId.g.cs");
+    }
+}
+```
