c# - Nunit 测试 dll，单独运行通过，一起运行第二个失败

Question

我有一套 nunit 测试，在测试运行器中运行。

2 个独立的 dll，

如果我独立运行它们，它们都可以工作。如果我同时运行它们，则第二个失败。

我们正在使用 Structure Map 2.5.3

我已将问题追溯到我们的 NH session 生命周期。

     x.BuildInstancesOf<INHFactory>()
                .AddInstances(z => z
                    .OfConcreteType<NHFactory>()
                    .WithName("JCDC")
                )
                .CacheBy(InstanceScope.Singleton);

如果我分别运行它们，则每次都会创建 session ，但如果同时运行它们，则会重复使用同一个 session ，从而导致崩溃。

我试过实例作用域线程，不开心，我试过用 ObjectFactory.ResetDefaults() 手动回收结构映射；在我的测试夹具拆解中。

没有快乐。

有没有办法强制 nunit 在单独的线程中运行它们？还是回收 dll 之间的结构映射工厂(在基础测试的拆卸中)？

还有其他方法可以解决这个问题吗？

Answer 1

假设使用 nunit 2.x，使用 nunit-console 选项/process:Multiple 在单独的进程中运行每个程序集。
