测试插件

SDK 0.1.0-alpha.4

PCLN.Plugin.Testing 提供不启动 PCL N 的内存宿主。你可以验证初始化、服务调用、命令、设置、任务、UI 注册和生命周期释放。

创建测试项目

powershell
dotnet new mstest -n ExamplePlugin.Tests --framework net10.0
dotnet add ExamplePlugin.Tests package PCLN.Plugin.Testing --version 0.1.0-alpha.4
dotnet add ExamplePlugin.Tests reference ExamplePlugin.csproj

测试包只应进入测试项目,不要放进 .pnp

创建测试 Context

csharp
using PCL.N.Plugin;
using PCL.N.Plugin.Testing;

PluginDescriptor descriptor = new(
    new PluginId("dev.example.plugin"),
    "Example Plugin",
    PluginVersion.Parse("0.1.0"));

await using TestPluginContext context = new(
    descriptor,
    new PluginApiVersion(0, 2));

Context 自动提供:

  • 独立临时目录;
  • 收集日志的 CollectingPluginLogger
  • 立即执行的 Dispatcher;
  • 可注入的服务和 Capability 容器;
  • 逆序释放注册项的测试 Lifetime。

测试命令与通知

csharp
[TestMethod]
public async Task Plugin_registers_command_and_shows_notification()
{
    PluginDescriptor descriptor = new(
        new PluginId("dev.example.plugin"),
        "Example Plugin",
        PluginVersion.Parse("0.1.0"));

    await using TestPluginContext context = new(descriptor, new PluginApiVersion(0, 2));
    TestPluginCommandService commands = new();
    TestPluginNotificationService notifications = new();
    context.TestServices.Add<IPluginCommandService>(commands);
    context.TestServices.Add<IPluginNotificationService>(notifications);

    ExamplePlugin plugin = new();
    await plugin.InitializeAsync(context, CancellationToken.None);

    Assert.AreEqual(1, commands.Commands.Count);
    await commands.InvokeAsync("dev.example.plugin.run");
    CollectionAssert.Contains(notifications.Messages.ToArray(), "info:完成");
}

测试设置

csharp
TestPluginSettingsStore settings = new();
context.TestServices.Add<IPluginSettingsStore>(settings);

PluginSettingKey<int> key = new("refresh-minutes");
await settings.SetAsync(key, 15);
Assert.AreEqual(15, await settings.GetAsync(key, 5));

测试实例读取

csharp
TestPluginInstanceReadService instances = new(
[
    new PluginInstanceInfo("survival", "生存服", @"D:\Games\Minecraft\survival")
]);

context.TestServices.Add<IPluginInstanceReadService>(instances);

测试不要依赖该示例 Windows 路径真实存在;它只是 DTO 数据。

测试设置页 Capability

csharp
InMemoryPluginSettingsPageCapability pages = new();
context.TestCapabilities.Add<IPluginSettingsPageCapability>(pages);

await plugin.InitializeAsync(context, CancellationToken.None);

Assert.AreEqual(1, pages.Pages.Count);
Assert.AreEqual("dev.example.plugin.settings", pages.Pages[0].Id);

验证释放

csharp
TestPluginCommandService commands = new();
TestPluginContext context = new(descriptor, new PluginApiVersion(0, 2));
context.TestServices.Add<IPluginCommandService>(commands);

await plugin.InitializeAsync(context, CancellationToken.None);
Assert.AreEqual(1, commands.Commands.Count);

await context.DisposeAsync();
Assert.AreEqual(0, commands.Commands.Count);

这能发现忘记 context.Lifetime.Track(...) 的注册泄漏。

推荐测试矩阵

  • required 服务齐全时成功初始化;
  • optional 服务缺失时正常降级;
  • 取消 Token 时任务结束;
  • 重复命令/页面 ID 会失败;
  • 设置默认值和更新值正确;
  • UI Surface 存在/缺失两种路径;
  • Context 释放后注册项消失;
  • Manifest 通过 PluginManifestValidator.ParseAndValidate
  • Release 构建实际生成 .pnp

仓库中的 SDK 测试和 examples/HelloPlugin 可作为基线。
