❔ FluentAssertions excluding collection elements

I have two IEnumerable<Claim> tmp1, tmp2 and I want to see if they are equal, except for the claims "exp", "nbf", "iat" because those are timestamps and dependent on the execution time. How can I solve this without having to mock every single thing that gives a time?

tmp1.Should().BeEquivalentTo(tmp2, options =>
        {
            options.Excluding(x => x.Type == JwtRegisteredClaimNames.Exp);
            options.Excluding(x => x.Type == JwtRegisteredClaimNames.Iat);
            options.Excluding(x => x.Type == JwtRegisteredClaimNames.Nbf);
            return options;
        });

maybe use linq then?

var claimsToExclude = new List<string>
{
    JwtRegisteredClaimNames.Exp,
    JwtRegisteredClaimNames.Iat,
    JwtRegisteredClaimNames.Nbf
};

var tmp1Filtered = tmp1.Where(x => !claimsToExclude.Contains(x.Type));
var tmp2Filtered = tmp2.Where(x => !claimsToExclude.Contains(x.Type));

tmp1Filtered.Should().BeEquivalentTo(tmp2Filtered);

I don't think there's another way of doing what you want to do using BeEquivalentTo.

or maybe you can try this too:

var claimsToCompare = tmp1.Except(new[]
{
    new Claim(JwtRegisteredClaimNames.Exp, ""),
    new Claim(JwtRegisteredClaimNames.Iat, ""),
    new Claim(JwtRegisteredClaimNames.Nbf, "")
});

claimsToCompare.Should().BeEquivalentTo(tmp2, options =>
{
    return options;
});

alright that will do

thanks!
