如何在ASP中使用依赖注入测试控制器。XUnit的网络核心?

我正在写我的ASP。NET Core Web API,我想开始用XUnit编写单元测试(我知道,现在有点晚了,但是,嘿,晚一点总比没有好),但我这里有一些复杂的依赖注入。这是我的样本 控制器 课程:

public class UnitController : MyController {

  private readonly MyContext _context;

  public UnitController(MyContext context) {
    _context = context;
  }
}

和 MyContext 课程:

  public class MyContext : DbContext {
    private readonly IHttpContextAccessor _httpContext;

    public MyContext(DbContextOptions options, IHttpContextAccessor httpContext) : base(options) {
      _httpContext = httpContext;
    }
  }

还有我的 配置服务 方法 创业。反恐精英 :

public void ConfigureServices(IServiceCollection services) {
  services.AddDbContext<MyContext>(options => options.UseMySql(Configuration.GetConnectionString("MyContext"))
    .ConfigureWarnings(warnings => warnings.Ignore(RelationalEventId.QueryClientEvaluationWarning)));
  services.AddHttpContextAccessor();
  services.AddMvc();
}

还有我可怜的XUnit班:

  public class UnitControllerTest {
    private readonly MyContext _context;

    public UnitControllerTest() {
      var configuration = new Mock<IConfiguration>().Object;
      var dbOptions = new DbContextOptionsBuilder().UseMySql(configuration.GetConnectionString("MyContext"));
      _context = new Mock<MyContext>(dbOptions).Object;
    }

    [Fact]
    public void AddUnit_InvalidModel_ShouldReturnBadRequest() {
      var controller = new UnitController(_context);
      var testUnit = new Unit();
      var result = controller.AddUnit(testUnit);

      Assert.Equal(typeof(BadRequestObjectResult), result.GetType());
    }   
  }

我的问题是,

如何正确编写测试?
