如何使用Fluent断言检查列表 [英] How to check a list is ordered using Fluent Assertions

问题描述

我正在使用specflow编写一些单元测试，并且需要一种方法来检查对象列表是否由特定属性排序.目前，我正在这样做，但是我不确定这是否是最好的解决方法.

I am writing some unit tests using specflow and need a way to check whether a list of objects is ordered by a specific property. Currently I am doing it like this, but I am not sure if this is the best way to go about it.

var listFromApi = listOfObjects;

var sortedList = listFromApi.OrderBy(x => x.Property);

Assert.IsTrue(listFromApi.SequenceEqual(sortedList));

是否可以使用Fluent断言来实现此目的?

Is there a nice way this can be done using Fluent Assertions?

推荐答案

是.您可以将BeInAscendingOrder与lambda一起使用.

Yes. You can use BeInAscendingOrder with a lambda.

listFromApi.Should().BeInAscendingOrder(x => x.Property);

为了更加清晰地牺牲性能，您还可以声明内容等效性:

For extra clarity at the expense of performance, you can also assert on content equivalence:

listFromApi.Should().BeEquivalentTo(listOfObjects)
    .And.BeInAscendingOrder(x => x.Property);
