这个测试名称是否略高于顶部

Question

正如标题所示,这个测试名称只是顶部的一点吗？

WhenChargeIsGreaterThanRestingChargeButLessThanChargeRestApproachStep_OnUpdate_ChargeIsSetToRestingCharge

关于如何改进这个的任何建议？或者它是好的吗？

下面是整个测试夹具,因此您可以获得一些上下文:)

像这样布局测试的一种流行方法是使用具有Given/When/Then类型词汇表的嵌套类,如典型的BDD实践所建议的,例如

public class NeuronStory
{
    public class GivenChargeIsGreaterThanRestingCharge
    {
        public class GivenChargeIsLessThanChargeRestApproachStep
        {
            public class WhenUpdated
            {
                public void ThenChargeIsSetToRestingCharge()
                {
                }
            }
        }
    }
}

这样你也可以GivenChargeIsGreaterThanRestingCharge在同一个地方嵌套其他适合故事情节的测试.

我个人认为方法名称永远不会太长,只要它们是描述性的.

单元测试名称往往更长,因为它们必须包含更多信息.这对我来说也很好,因为它们只出现在方法签名和测试列表中(这是你想要一个好名字的地方),你永远不会从任何其他代码中调用它们.
