Question

我使用NUnit，应该和实体框架内存中的SQLite数据库进行集成测试，并且卡在我的两个没有执行任何数据库调用的测试用例上（没有等待执行）。 / p>

控制器：

[TestFixture]
public class DeleteOrganisations : TestBase
{
    private OrganisationController _organisationController;

    [OneTimeSetUp]
    public void OneTimeSetUp()
    {
        //Controller
        _organisationController = new OrganisationController(null, Mapper, OrganisationService, StatusService, AuthenticationService);

        //Object Mother
        ObjectMother.InsertTestData();
    }

    public static IEnumerable TestCases
    {
        get
        {
            yield return new TestCaseData(new DeleteOrganisationsModel { OrganisationIds = new List<int>() { 1 } }, 0, 1).SetName("DeleteOrganisations_Should_Delete_Data_When_OrganisationId_Exist");

            yield return new TestCaseData(new DeleteOrganisationsModel { OrganisationIds = null }, 0, 0).SetName("DeleteOrganisations_Should_Not_Delete_Data_When_Null");
            yield return new TestCaseData(new DeleteOrganisationsModel { OrganisationIds = new List<int>() { 2 } }, 0, 0).SetName("DeleteOrganisations_Should_Not_Delete_Data_When_OrganisationId_Not_Exist");
        }
    }

    [Test, TestCaseSource(nameof(TestCases))]
    public async Task Test(DeleteOrganisationsModel model, int removedOrganisationCountBefore, int removedOrganisationCountAfter)
    {
        //Before
        int resultBefore = Database.Organisation.Include(o => o.Status).Count(o => o.Status.Name == StatusEnum.Status.Removed.ToString());

        resultBefore.ShouldBe(removedOrganisationCountBefore);

        //Delete
        await _organisationController.DeleteOrganisations(model);

        //After
        int resultAfter = Database.Organisation.Include(o => o.Status).Count(o => o.Status.Name == StatusEnum.Status.Removed.ToString());

        resultAfter.ShouldBe(removedOrganisationCountAfter);
    }
}

测试

StatusModel status = await _statusService.GetStatus(StatusTypeEnum.StatusType.Organisation, StatusEnum.Status.Removed);

测试用例1通过，因为

Message: System.NullReferenceException : Object reference not set to an instance of an object.

被调用，等待结果。

测试用例2和3失败，因为函数中没有等待（if语句）。

消息：System.NullReferenceException：未设置对象引用一个对象的实例。

我可能会为没有执行任何await语句的结果创建另一个测试，并跳过新测试函数的异步任务，但后来我会收到消息：

因为没有等待此调用，所以执行当前方法在通话结束前继续。考虑应用“等待”＃39; 运算符到调用的结果。

测试可能会通过，但我不喜欢两个测试加上语法错误的想法。

你会做什么？

Facepalm - 我忘了在testbase中注入localizer类。对不起，我的坏人。

这一行就在这里：

if (organisations == null || organisations.Count == 0)
{
    return Ok(new GenericResultModel(_localizer["Could_not_find_organisations"]));
}

c＃测试异步任务 - 测试用例忽略await - NullReferenceException
