How to compare case insensitive string using FluentAssertions? C# [duplicate]

Question

How can I easy compare string case insensitive using FluentAssertions?

Something like:

symbol.Should().Be(expectedSymbol, StringComparison.InvariantCultureIgnoreCase);

Edit: Regarding possible duplicate and code: symbol.Should().BeEquivalentTo(expectedSymbol);

it is comparing using CurrentCulture. And it will brake in situation like Turkish culture. Where Thread.CurrentThread.CurrentCulture = new CultureInfo("tr-TR", false); string upper = "in".ToUpper(); // upper == "İN" "in".Should().BeEquivalentTo("In"); // It will fail

so the part "StringComparison.InvariantCultureIgnoreCase" is crucial here.

Answer 1

You can use

symbol.ToLower().Should().Be(expectedSymbol.ToLower());

OR

Instead of Be use BeEquivalentTo

symbol.Should().BeEquivalentTo(expectedSymbol);

BeEquivalentTo metadata states

Asserts that a string is exactly the same as another string, including any leading or trailing whitespace, with the exception of the casing.
