我正在向我的Container
注册多种类型,实现各种接口。
以某种程序化的方式,我希望有一个单元测试来检查所有解析是否成功,这意味着注册中没有循环或缺少依赖。
我尝试添加这样的内容:
[TestMethod]
public void Resolve_CanResolveAllTypes()
{
foreach (var registration in _container.ComponentRegistry.Registrations)
{
var instance = _container.Resolve(registration.Activator.LimitType);
Assert.IsNotNull(instance);
}
}
但是在第一次运行解析Autofac.Core.Lifetime.LifetimeScope
时它失败了,尽管我有接受ILifetimeScope
作为参数的方法,并且在我的应用程序启动时就可以正常运行。
答案 0 :(得分:2)
以下代码终于为我工作了:
private IContainer _container;
[TestMethod]
public void Resolve_CanResolveAllTypes()
{
foreach (var componentRegistration in _container.ComponentRegistry.Registrations)
{
foreach (var registrationService in componentRegistration.Services)
{
var registeredTargetType = registrationService.Description;
var type = GetType(registeredTargetType);
if (type == null)
{
Assert.Fail($"Failed to parse type '{registeredTargetType}'");
}
var instance = _container.Resolve(type);
Assert.IsNotNull(instance);
Assert.IsInstanceOfType(instance, componentRegistration.Activator.LimitType);
}
}
}
private static Type GetType(string typeName)
{
var type = Type.GetType(typeName);
if (type != null)
{
return type;
}
foreach (var assembly in AppDomain.CurrentDomain.GetAssemblies())
{
type = assembly.GetType(typeName);
if (type != null)
{
return type;
}
}
return null;
}
