c# - 在集成测试中设置环境

Question

我想使用 WebApplicationFactory 在我的集成测试中设置环境.默认情况下，env 设置为 Development .我的 Web 应用程序工厂的代码如下所示:

public class CustomWebApplicationFactory<TStartup> : WebApplicationFactory<TStartup>
    where TStartup : class
{
    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        builder.UseSolutionRelativeContentRoot(AppContext.BaseDirectory);

        base.ConfigureWebHost(builder);
    }

    protected override IWebHostBuilder CreateWebHostBuilder()
    {
        return WebHost.CreateDefaultBuilder()
            .UseStartup<TStartup>()
            .UseEnvironment("test"); // i want to launch `test` environment while im
                                     // testing my app
    }
}

当我开始调试时 Startup类(当我运行测试时)我仍然收到 Development环境:

public Startup(IHostEnvironment env)
{
    var builder = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile("appsettings.json", false, true)
        .AddJsonFile($"appsettings.{env.EnvironmentName}.json", true)
        // env.EnvironmentName is set to 'Development' while i set it to 'test'
        // in my WebApplicationFactory
        .AddEnvironmentVariables();

    Configuration = builder.Build();
}

如何在 WebApplicationFactory 中设置环境适本地？或者也许如何仅在启动时更改测试策略我取决于 appsettings文件？

我遇到了同样的问题，以下对我有用:

protected override void ConfigureWebHost(IWebHostBuilder builder)
{
     builder.UseEnvironment("Test");
}
