Question

我正在尝试对asp.net Core 2.1项目进行一些集成测试。

我在启动文件中初始化了我的连接字符串，但是当我运行测试时，它在处理程序中仍然为空，我的代码出了什么问题？

    [TestMethod]
    public async Task Method1()
    {
        var webHostBuilder = new WebHostBuilder()
                            .UseEnvironment("Development") 
                            .UseStartup<Startup>(); 
        HttpRequestMessage getRequest = new HttpRequestMessage(HttpMethod.Get, "api/action")
        {                
        };
        getRequest.Headers.Add("userId", "4622");
        getRequest.Headers.Add("clientId", "889");

        using (var server = new TestServer(webHostBuilder))
        using (var client = server.CreateClient())
        {
            var result = await client.SendAsync(getRequest);  
            ...             
        }
   }

启动

public Startup(IConfiguration configuration)
{
        Configuration = configuration;

}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
    ...
    services.Configure<SqlConfig>(options =>
    {
       options.ConnectionString = Configuration.GetConnectionString("DefaultConnection");
    });
    ...
}

SqlConfig

public class SqlConfig
{
    public string ConnectionString { get; set; }
}

存储库

public abstract class SqlServerQueryHandler<TQuery, TResult> : BaseQueryHandler<TQuery, TResult>
     where TQuery : IQuery<TResult>
{
   public SqlServerQueryHandler(IOptions<SqlConfig> connectionString)
    {
        this.ConnectionString = connectionString.Value.ConnectionString;
    }

   protected string ConnectionString { get; }
}

解决我的问题的方法是以下代码：

public class TestStartup : Startup
{
    public TestStartup(IConfiguration configuration, IHostingEnvironment env) : base(configuration)
    {
        var builder = new ConfigurationBuilder()
           .SetBasePath(env.ContentRootPath)
           .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
           .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
           .AddEnvironmentVariables();
        this.Configuration = builder.Build();
    }

通过接口在输出目录中包含appsettings.json

在集成测试中检索连接字符串
