c# - 在 JustMock 中找不到 TestFixtureSetUpAttribute？

Question

我正在使用 C#、.NET Framework 4.7、Nunit 3.8.0 和 JustMock Lite 2017.2.821.1 开发 TDD 测试。

当我这样做时:

IGenericRepository<ProductionOrder> _proOrdRepository = 
                Mock.Create<IGenericRepository<ProductionOrder>>();

我得到以下异常:

System.TypeInitializationException occurred
  HResult=0x80131534
  Message=An exception occurred in the type initializer of 'Telerik.JustMock.Core.Context.MockingContext'.
  Source=Telerik.JustMock
  StackTrace:
   at Telerik.JustMock.Core.Context.MockingContext.get_CurrentRepository()
   at Telerik.JustMock.Mock.<>c__44`1.<Create>b__44_0()
   at Telerik.JustMock.Core.ProfilerInterceptor.GuardInternal[T](Func`1 guardedAction)
   at Telerik.JustMock.Mock.Create[T]()
   at MyProjects.Tests.LoadFinishedTrzlBatchTest.SetUpLoadFinishedTrzlBatch() in D:\MyProjects\MyProject\LoadFinishedTrzlBatchTest.cs:line 25

Inner Exception 1:
InvalidOperationException: Some attribute type among NUnit.Framework.TestFixtureSetUpAttribute, nunit.framework,NUnit.Framework.TestFixtureTearDownAttribute, nunit.framework not found.

这是我第一次使用 TDD 和 JustMock 做一些事情，我不知道如何解决这个问题。

我的测试类是:

[TestFixture]
class LoadFinishedTrzlBatchTest
{
    private LoadFinishedTrzlBatch sut;
    private IGenericRepository<ProductionOrder> _proOrdRepository;

    [SetUp]
    public void SetUpLoadFinishedTrzlBatch()
    {
        _proOrdRepository = 
            Mock.Create<IGenericRepository<ProductionOrder>>();
        var batchRepository =
            Mock.Create<IGenericRepository<Batch>>();
        var codeRepository =
            Mock.Create<IGenericRepository<Code>>();
        var aggRepository =
            Mock.Create<IGenericRepository<Aggregation>>();
        var aggChildrenRepository =
            Mock.Create<IGenericRepository<AggregationChildren>>();

        sut = new LoadFinishedTrzlBatch(
            _proOrdRepository,
            batchRepository,
            codeRepository,
            aggRepository,
            aggChildrenRepository);
    }

    [TestCaseSource(nameof(ShouldThrowArgumentSource))]
    public void ShouldThrowArgumentExceptionWithInvalidProductionOrderName(string productionOrderName)
    {
        // Assert
        Assert.That(() => sut.ExistsProductionOrder(productionOrderName), Throws.TypeOf<ArgumentNullException>());
    }

    [Test]
    public void ShouldExistsProductionOrder()
    {

        // Arrange
        var productionOrderName = "ProOrd";
        var orders = new List<ProductionOrder>() {
            new ProductionOrder { Name = productionOrderName },
            new ProductionOrder { Name = "Dummy for Filter" }
        };

        Mock.Arrange(() => _proOrdRepository
            .SearchFor(Arg.IsAny<Expression<Func<ProductionOrder, bool>>>()))
            .Returns((Expression<Func<ProductionOrder, bool>> expression) =>
                orders.Where(expression.Compile()).AsQueryable())
            .MustBeCalled();

        // Act
        var actual = sut.ExistsProductionOrder(productionOrderName);

        // Assert
        Assert.IsTrue(actual);
    }

    private static IEnumerable ShouldThrowArgumentSource()
    {
        yield return string.Empty;
        yield return null;
        yield return " ";
    }
}

有什么想法吗？

更新:

我删除了 SetUpLoadFinishedTrzlBatch 方法并将所有内容移动到 ShouldExistsProductionOrder 方法中，我得到了同样的错误。

[Test]
public void ShouldExistsProductionOrder()
{
    LoadFinishedTrzlBatch sut;
    IGenericRepository<ProductionOrder> _proOrdRepository;

    _proOrdRepository =
        Mock.Create<IGenericRepository<ProductionOrder>>();
    var batchRepository =
        Mock.Create<IGenericRepository<Batch>>();
    var codeRepository =
        Mock.Create<IGenericRepository<Code>>();
    var aggRepository =
        Mock.Create<IGenericRepository<Aggregation>>();
    var aggChildrenRepository =
        Mock.Create<IGenericRepository<AggregationChildren>>();

    sut = new LoadFinishedTrzlBatch(
        _proOrdRepository,
        batchRepository,
        codeRepository,
        aggRepository,
        aggChildrenRepository);

    // Arrange
    var productionOrderName = "ProOrd";
    var orders = new List<ProductionOrder>() {
        new ProductionOrder { Name = productionOrderName },
        new ProductionOrder { Name = "Dummy for Filter" }
    };

    Mock.Arrange(() => _proOrdRepository
        .SearchFor(Arg.IsAny<Expression<Func<ProductionOrder, bool>>>()))
        .Returns((Expression<Func<ProductionOrder, bool>> expression) =>
            orders.Where(expression.Compile()).AsQueryable())
        .MustBeCalled();

    // Act
    var actual = sut.ExistsProductionOrder(productionOrderName);

    // Assert
    Assert.IsTrue(actual);
}

我认为问题出在 JustMock 上。

Answer 1

JustMock relies on TestFixtureSetUpAttribute and TestFixtureTearDownAttribute对于 NUnit 3 和 NUnit 2。

这两个属性在 NUnit 3.0 中被弃用，并且刚刚在 NUnit 3.8 中被删除。 JustMock 应该更新以使用它们的替代品，OneTimeSetUp 和 OneTimeTearDown。

作为用户 - 在解决此问题之前，您不能使用高于 NUnit 3.7.1 的版本。您可以将问题报告给 JustMock here .

该问题自 JustMock 2018 R1 版本发布后已修复。
