{✓} JSON Validator for Fluent Assertions

[!warning] Due to licencing changes, the FluentAssertions library won't be updated above v7.1 (the last truely free version). We recommend using Shouldly and our Shouldly extension instead.

This project provides a simple way to validate JSON objects in dotnet. The main use for the tool is in integration tests where you would — ideally — validate an API JSON response manually instead of using the model classes.

Usage

• The JsonValidator.FluentAssertions package depends on and uses both FluentAssertions and the basic JsonValidator package.
• This package provides extensions that can be accessed through FluentAssertions' Should() method.
• Available extensions:
  • for System.Text.Json.JsonDocument: Match(...) checks whether the JSON document matches the input object in both structure and values.
  • for System.Net.Http.HttpResponseMessage: HaveJsonBody(...) checks whether the HTTP response's body as a JSON string matches the input object in both structure and values.

Examples

For JsonDocument:

var json = JsonDocument.Parse(myJsonString);

json.Should().Match(
  new
  {
      name = "Anna Smith",
      level = 2,
  },
  "Because...");

For HttpResponseMessage:
