Usage

Be sure to include using FluentAssertions.Json; otherwise false positives may occur.

using FluentAssertions;
using FluentAssertions.Json;
using Newtonsoft.Json.Linq;

... 
var actual = JToken.Parse(@"{ ""key1"" : ""value"" }");
var expected = JToken.Parse(@"{ ""key2"" : ""value"" }");
actual.Should().BeEquivalentTo(expected);

You can also use IJsonAssertionOptions<> with Should().BeEquivalentTo() assertions, which contains helper methods that you can use to specify the way you want to compare specific data types.

Example:

using FluentAssertions;
using FluentAssertions.Json;
using Newtonsoft.Json.Linq;

... 
var actual = JToken.Parse(@"{ ""value"" : 1.5 }");
var expected = JToken.Parse(@"{ ""value"" : 1.4 }");
actual.Should().BeEquivalentTo(expected, options => options
                .Using<double>(d => d.Subject.Should().BeApproximately(d.Expectation, 0.1))
                .WhenTypeIs<double>());
