Question

运行Abp.AutoMapper.Tests测试项目会给出随机结果，并且通常会因错误而失败。我特别在谈论此测试：“ AutoMapper_Inheritance_Tests.AutoMapKey_MapTo_DerivedCollection_Tests”

我在Azure DevOps中运行生成过程。我之前使用过C＃Make步骤，但是将其更改为其他内容并没有帮助。即使您运行提供的构建脚本（build.ps1），结果也不会相同。这项测试可能会失败，也可能不会失败...取决于我的心情。在我看来，偶尔的失败可能与某些底层逻辑的异步性质有关。

                            new MyAutoMapKeyClass1 { Id = 2, TestProp = "New test value 2"}
                        };

            var list2 = new List<MyAutoMapKeyClass2>
                        {

            var list5 = new List<MyAutoMapKeyClass5>
                        {
                            new MyAutoMapKeyClass5 { Id = 1, SecondId = 2, TestProp = "New test value 1"},

            var list7 = new List<MyAutoMapKeyClass7>
                        {
                            new MyAutoMapKeyClass7 { Id = 1, SecondId = 2,  TestProp = "New test value 1"},
                            new MyAutoMapKeyClass7 { Id = 2, SecondId = 3,  TestProp = "New test value 2"}
                        };

            var list8 = new List<MyAutoMapKeyClass8>
                        {

            _mapper.Map(list1, list2);
            list2.Count.ShouldBe(2);
            list2[0].TestProp.ShouldBe("New test value 1");
            list2[0].Value.ShouldBe(5);
            list2[1].TestProp.ShouldBe("New test value 2");
            list2[1].Value.ShouldBe(10);

            _mapper.Map(list3, list4);
            list4.Count.ShouldBe(2);
            list4[0].TestProp.ShouldBe("New test value 1");

            list4[1].Value.ShouldBe(10);

            _mapper.Map(list5, list6);
            list6.Count.ShouldBe(2);
            list6[0].TestProp.ShouldBe("New test value 1");
            list6[0].Value.ShouldBe(5);
            list6[1].TestProp.ShouldBe("New test value 2");
            list6[1].Value.ShouldBe(10);

            _mapper.Map(list7, list8);

            list8[1].Value.ShouldBe(10);
        }
    }

失败的块实际上是'_mapper.Map（list1，list2）;' 预期结果将始终相同，即5。相反，我看到了错误：

针对C：\ agents \ agent3_work \ 1 \ s \ test \ Abp.AutoMapper.Tests \ bin \ Debug \ netcoreapp2.2 \ Abp.AutoMapper.Tests.dll（.NETCoreApp，Version = v2.2）运行测试 Microsoft（R）测试执行命令行工具版本15.9.0 版权所有（c）Microsoft Corporation。保留所有权利。

开始执行测试，请稍候... [xUnit.net 00：00：02.79] Abp.AutoMapper.Tests.AutoMapper_Inheritance_Tests.AutoMapKey_MapTo_DerivedCollection_Tests [FAIL] Abp.AutoMapper.Tests.AutoMapper_Inheritance_Tests.AutoMapKey_MapTo_DerivedCollection_Tests失败错误信息： Shouldly.ShouldAssertException：list2 [0] .Value 应该 5 但是是 0 堆栈跟踪：在Abp.AutoMapper.Tests.AutoMapper_Inheritance_Tests.AutoMapKey_MapTo_DerivedCollection_Tests（）中位于C：\ agents \ agent3_work \ 1 \ s \ test \ Abp.AutoMapper.Tests \ AutoMapper_Inheritance_Tests.cs：line 219

同样，即使我在本地计算机上运行测试，结果也可能相同，即该测试在此特定位置失败。但是，如果我立即在“测试资源管理器”中单独重新运行此测试，那么它将毫无问题。
