In Fluent Assertions when comparing objects with DateTime properties there are sometimes a slight mismatch in the milliseconds and the comparison fail. The way we get around it is to set the compar...

Using fluent assertions, I would like to assert that a given string contains either one of two strings: actual.Should().Contain("oneWay").Or().Should().Contain("anotherWay"); // eiter value shoul...

Can anybody summarize differences and usage scope between them? I read SO articles, ShouldBeEquivalientTo(): ShouldBeEquivalentTo() is intended to be used for comparing complex object graphs rat...

Using FluentAssertion 3.1.229, how do you compare the content of two distinct MemoryStream? Writing actualStream.Should().Be(expectedStream); yields the following error: System.IO.MemoryStream { ...

In FluentAssertions, you can make various claims in various formats. x.Should().BeEquivalentTo(y); x.ShouldBeEquivalentTo(y); are both valid assertions. Why is Should a method and not a propert...

I have a .net 4.0 test project which is throwing a method not found exceptions for the Should() extension method. Then I noticed it also was throwing exceptions for an int type as well. Does anyb...

How to check that each object of a collection conforms to a given predicate? E.g.: check for each item (from a given collection) that it matches a given predicate (MyPredicate). Code should probabl...

I've got a pair of Lists I'm trying to compare using Fluent Assertions. I can code up a comparison easily, but I'd like to use Fluent Assertions so that I can get the reason to show up in the test ...

I am trying to check an async method throws concrete exception. For that I am using MSTEST and FluentAssertions 2.0.1. I have checked this Discussion on Codeplex and to see how it works with asyn...

I have two arrays of double. Is there a way using FluentAssertions to compare the arrays element-by-element, using the .BeApproximately() technique? One range value would suffice for the entire ar...

I have the following spec BidirectionalGraph Fixture = new BidirectionalGraph(); public void VerticesShouldBeAbleToAssociateMultipleEdges() { int a = 0; int b = 1; int c = 2; Fixture.AddEdge...

I have a test that verifies the collection output of a method. This variation of the test passes: [TestMethod, TestCategory("BVT")] public void TheStatusesAreReturned() { var expectedUnprocess...

I'm implementing a special case of an immutable dictionary, which for convenience implements IEnumerable<KeyValuePair<Foo, Bar>>. Operations that would ordinarily modify the dictionary ...

In my NUnit/FluentAssertions tests I compare the complex object returned from my system with a reference one using the following code: response.ShouldBeEquivalentTo(reference, o => o.Excluding...

I have two extension methods: public static IPropertyAssertions<T> ShouldHave<T>(this T subject) { return new PropertyAssertions<T>(subject); } public static IPropertyAssertion...

I was writing some unit tests for a utility library when I came across a test I would expect to fail that actually passed. The issue is related to comparing two float variables, versus comparing on...

I would like to "combine" Fluent Assertion's collection assertions and property assertions, e.g. assert that two IEnumerable's are pairwise-equal using property-by-property (possibly "nested") comp...
