How to unit test an Action method which returns JsonResult?

Question

If I have a controller like this:

[HttpPost]
public JsonResult FindStuff(string query) 
{
   var results = _repo.GetStuff(query);
   var jsonResult = results         


        

Answer 1

If in the test you know what exactly the Json data result should be then you can just do something like this:

result.Data.ToString().Should().Be(new { param = value}.ToString());

P.S. This would be if you had used FluentAssertions.Mvc5 - but it shouldn't be hard to convert it to whatever testing tools you use.
