如何使用MassTransit测试工具通过构造函数依赖项注入来测试Consumer? [英] How to use MassTransit test harness to test Consumer with constructor dependency injection?

问题描述

我有一些消息使用者，它们通过构造函数获取依赖关系，我想在单元测试中介绍它们.MassTransit的测试工具是否提供一种使用构造函数参数注册使用者的方法?

I have some message consumers that take dependencies through the constructor, and I would like to cover them in unit tests. Does MassTransit's test harness provide a way to register consumers with constructor parameters?

推荐答案

创建消费者测试工具时，您可以指定工厂方法或消费者工厂.

You can specify a factory method, or a consumer factory, when creating a consumer test harness.

harness.Consumer<T>(() => new T());

您可以在代码中找到三种标准扩展方法:

You can find the three standard extension methods in the code:

更新:MassTransit现在具有对测试工具的容器支持

UPDATE: MassTransit now has container support for the test harness
