嘲笑UnitOfWorkManager。单元测试中的电流

UnitOfWorkManager.Current (nullreference异常)。这个 _unitOfWorkManager 类型: IUnitOfWorkManager

我正在测试以下web api代码:

[HttpPost]
public async Task<IHttpActionResult> Subscription(SubscriptionInputDto model)
{
    if (!await VendorHasAccess(model.OrganizationId))
        return StatusCode(HttpStatusCode.Forbidden);

    var input = new Subscription
    {
        ...
    };

    var data = await _subscriptionRepository.InsertAsync(input);

    await _unitOfWorkManager.Current.SaveChangesAsync();

    return Ok(data.MapTo<SubscriptionDto>());
}

[Fact]
public async Task Should_Create_New_Subscription()
{
    //Arrange
    var organization = await UsingDbContextAsync(async context => await context.VendorOrganizations.FirstOrDefaultAsync());
    var input = new SubscriptionInputDto { OrganizationId = organization.Id };

    //Act
    var actionResult = await _vendorController.Subscription(input);
    var response = actionResult as OkNegotiatedContentResult<SubscriptionDto>;

    //Assert
    Assert.NotNull(response);
    Assert.Equal(organization.Id, response.Content.OrganizationId);
}

我不知道或找不到任何关于如何解决问题的文档 UnitOfWorkManager。现在的 web API代码本身在生产中工作。
