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

Inner Exception 1:
InvalidOperationException: Some attribute type among NUnit.Framework.TestFixtureSetUpAttribute, nunit.framework,NUnit.Framework.TestFixtureTearDownAttribute, nunit.framework not found.
这是我第一次用 TDD 做一些事情，JustMock我不知道如何解决这个问题。
我的测试课是：
[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 " ";
}
}
任何的想法？
更新：
我已经删除了该方法SetUpLoadFinishedTrzlBatch并移动了该方法中的所有内容，但ShouldExistsProductionOrder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。
