How to get the API response to use in subsequent tests?

[adarmus]

Hi - love the library.

We want to use the ID from one request to construct a second request. How can we access the response model from the first outside of an "assert" expression?

Thanks, Adam

Hi, I work with Adam. If we just add a property to RestResponse:

public IApiClientResponse ApiResponse => Context.Response;

Then we can: var myResponse = JsonConvert.DeserializeObject< MyResponseModel>(response.ApiResponse.Content); and access anything we need.

Thanks, Mark

I have added a couple of PRs that allow this to be done (in different ways).

hey guys @adarmus @marktilleytlc Thanks for the feedback and contribution!

As you figured it out, there is not built in way to do what you need. And thanks for creating the Action Rule.

However I feel that "Action" breaks a little bit the "Fluent" syntax and the Assertion intention of the framework.

I understand the benefit of an action before and after a request, but also an easy way for people to add custom validations.

So do you reckon that the example below would be helpful for you all?

string headerValue = "";
string login = "";
Rest.GetFromUrl("https://api.github.com/users/defunkt")
    .WithHeader("User-Agent", "RestFluencing Sample")
    .BeforeRequestDo(context => {
        // you can intercept the request for whatever reason
    })
    .AfterRequestDo(context => {
        // you can intercept the response for whatever reason
    })
    .Response()
    .Returns<GitHubUserModel>(model =>
    {
        // Here you can do action but also do inline specific validations
        // but also access the deserialized response
        login = model.login;
        return true;
    }, "Your reason why it failed - in your case you leave it blank since would never fail.")
    .ReturnsStatus(HttpStatusCode.OK)
    .Assert();

I will see if I can crack some of this code this weekend :)

Hi - I understand your concerns, and your suggestion looks good.

Thanks, Adam

I have uploaded the new package that includes the before and after request events and also a ReturnsModel that allows you to write inline validation.

You should still be able to use your custom rules if you added them as part of your project.

    // Arrange
    bool callFromRequest = false;
    var config = RestConfigurationHelper.Default();
    var request = config.Get("/null")
        .AfterRequest(context => { callFromRequest = true; });
    // Act
    request.Response().Assert();
    // Assert
    Assert.IsTrue(callFromRequest);

And

    Rest.Get("/product/apple", _configuration)
        .Response()
        .ReturnsModel<Product>(product => {
            return
                product.Name == "Apple";
        }, "My custom error message")
        .Execute()
        .ShouldPass();

Thank you Douglas, I have updated our code to use AfterRequest and it is working well.

Regards
