用于测试的 IHostingEnvironment

IHostingEnvironment for testing

我正在尝试使用 ABP 2.0.2 中的单元测试项目,当我 运行 选择测试 GetUsers_Test().

Message: Castle.MicroKernel.Handlers.HandlerException : Can't create component 'imfundoplatform.imfundoplatformCoreModule' as it has dependencies to be satisfied.

'imfundoplatform.imfundoplatformCoreModule' is waiting for the following dependencies:
- Service 'Microsoft.AspNetCore.Hosting.IHostingEnvironment' which was not registered.

我的 Core 模块的构造函数:

public imfundoplatformCoreModule(IHostingEnvironment env)
{
    _appConfiguration = AppConfigurations.Get(env.ContentRootPath, env.EnvironmentName, env.IsDevelopment());
}

我不知道如何将它传递给模块或让单元测试正常工作。请帮忙!

您不能注入 IHostingEnvironment ... 要获取内容根路径,请使用;

Directory.GetCurrentDirectory

可以 注入 IHostingEnvironment。但是你将不得不以一些奇怪的方式来做:

首先像这样创建一个模拟 IHostingEnvrionment class(根据您的需要进行调整):

public class MockHostingEnvironment : IHostingEnvironment, ISingletonDependency
{
    public string EnvironmentName
    {
        get => throw new NotImplementedException();
        set => throw new NotImplementedException();
    }

    public string ApplicationName
    {
        get => throw new NotImplementedException();
        set => throw new NotImplementedException();
    }
    public string WebRootPath { get; set; } = Path.Combine(Environment.CurrentDirectory, "wwwroot");
    public IFileProvider WebRootFileProvider
    {
        get => throw new NotImplementedException();
        set => throw new NotImplementedException();
    }

    public string ContentRootPath { get; set; } = Environment.CurrentDirectory;

    public IFileProvider ContentRootFileProvider
    {
        get => throw new NotImplementedException();
        set => throw new NotImplementedException();
    }
}

之后将此添加到您的 TestModule 的 Initialize()

public override void Initialize()
{
    (...)
    IocManager.Register<IHostingEnvironment, MockHostingEnvironment>(DependencyLifeStyle.Singleton);
}

请注意,使用 Environment.CurrentDirectory 是一种非常糟糕的做法。它可能指向不同的目录,具体取决于您的 CI、您的测试运行器、您的测试框架等。

如果您在测试中使用需要 IHostingEnvironment 的服务,您应该 使用此 MockHostingEnvironment。
