请问关于c的具体应用场景有哪些？

在测试我的 saga 函数中，我设置了自定义的传说：public WhenTestingMySага() { _mySaga=new MySaga { Data=new MySaga.MySagaData() }; } 我的测试断言未接收到重要数据会导致失败：[Fact] public void Not_Providing_Data() {

在我的测试构造函数中,我设置了我的传奇：

public When_Testing_My_Saga() { _mySaga = new MySaga { Data = new MySaga.MySagaData() }; }

我的测试断言未接收重要数据会导致失败：

[Fact] public void Not_Providing_Data_Should_Cause_A_Failure() { var context = new TestableMessageHandlerContext(); Should.Throw<NoDataProvidedFailure>(() => { _mySaga.Handle(new ImportDataReadMessage { ImportantData = null }, context).ConfigureAwait(false); }); }

SqlSaga中的实际代码：

public async Task Handle(ImportantDataReadMessage message, IMessageHandlerContext context) { if (message.ImportantData == null) { throw new NoDataProvidedFailure("Important data was not provided."); } await context.Send(Endpoints.MyEndpoint, new DoStuffWhenImportantDataProvided { Reference = message.Reference }); }

引发预期的失败,但测试表明相反：

Shouldly.ShouldAssertException _mySaga.Handle(new
ImportantDataReadMessage { Reference = string.Empty, ImportantData =
null }, context).ConfigureAwait(false);
should throw Service.Failures.NoDataProvidedFailure
but did not at Not_Providing_Data_Should_Cause_A_Failure () in mypath\When_Testing_My_Saga.cs:line 77

这真的很奇怪,因为如果我调试到处理程序,抛出线就会被击中.

有什么线索可能会发生什么？

PS：NoDataProvidedFailure继承自Exception,但被称为失败,表明它不可恢复(不会触发重试).

应该能够使用Do.ThrowAsync与Func< Task>在正确的线程上捕获异常以允许按预期执行测试.

[Fact] public async Task Not_Providing_Data_Should_Cause_A_Failure() { //Arrange var context = new TestableMessageHandlerContext(); //Act Func<Task> act = () => _mySaga.Handle(new ImportDataReadMessage { ImportantData = null }, context); //Assert await Should.ThrowAsync<NoDataProvidedFailure>(act); }
