如何提取用 ok 发送的字符串以在单元测试中检查它

Question

How can I extract the string sent with the ok to check it in test

  public IHttpActionResult PostConnect()
    {
        try
        {
            return Ok(result.ToString())
        }
        catch (Exception ex)
        {
            return BadRequest("An error");
        }
    }

I tried to do something but it didn't work

        [TestMethod]
    public void TestPostConnect()
    {
        var agentController = new Controller();
        IHttpActionResult actionResult = agentController.PostConnect();
        var okResult = actionResult as OkObjectResult;
    }

And how can I convert from string to json?

You shouldn't assume in your test that it is an OkObjectResult, that's the main reason for tests. Meaning you should expect it to be of type OkObjectResult. After that you can use the Value property to retrieve the string.

[TestMethod]
public void TestPostConnect()
{
    var agentController = new Controller();
    IHttpActionResult actionResult = agentController.PostConnect();
    var result = actionResult.Should().BeOfType<OkObjectResult>();
    result.Value.Should().BeOfType<string>();
    result.Value.Should().Be("your string");
}
