[英]How to check a list is ordered using Fluent Assertions
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. 我正在使用specflow编写一些单元测试,需要一种方法来检查对象列表是否按特定属性排序。 Currently I am doing it like this, but I am not sure if this is the best way to go about it.
目前我这样做,但我不确定这是否是最佳方式。
var listFromApi = listOfObjects;
var sortedList = listFromApi.OrderBy(x => x.Property);
Assert.IsTrue(listFromApi.SequenceEqual(sortedList));
Is there a nice way this can be done using Fluent Assertions? 有没有一种很好的方法可以使用Fluent Assertions完成?
Yes. 是。 You can use
BeInAscendingOrder
with a lambda. 您可以将
BeInAscendingOrder
与lambda一起使用。
listFromApi.Should().BeInAscendingOrder(x => x.Property);
For extra clarity at the expense of performance, you can also assert on content equivalence: 为了更加清晰而牺牲性能,您还可以断言内容等效:
listFromApi.Should().BeEquivalentTo(listOfObjects)
.And.BeInAscendingOrder(x => x.Property);
