How you approach testing an API depends on a lot of things. Will the API be a public API that will be consumed by some external people/systems, or is it a part of a larger product's infrastructure? API is a general term that is sometimes used to describe anything from a COM interface, to a DLL or JAR you can reference, to a REST web service. Different ...

I have had exactly the same assignment earlier this year, for APIs written in C#. Options I have (tried to) build a PoC for were:
SoapUI
Postman
Own framework built in C# using either RestSharp or HttpClient.
In agreement with the test lead and architecture team, we have decide to use our own C# API testing framework for the following reasons:
Ease of ...

You can use the combination of any unit testing framework (like NUnit, MSTest, XUnit) with additional nuget packages for the work with REST API itself
RestSharp (http://restsharp.org/) Probably the most popular and convenient REST HTTP Client for .Net.
RestAssured.Net (https://github.com/lamchakchan/RestAssured.Net) .Net port of Java's lib, may be easier ...

Choosing the tool is not the only decision you need to make when testing an API. As for any testing task you need to decide:
What aspects of the program are you testing? What application features do you want to cover with API testing? Are you going to verify some stateful scenarios (e.g. when user is logged in)? Or maybe you want to verify how an API ...

In general I think you should not expect a mocked front-end that's hooked up to the API calls for testing (however if you have one lucky you!). Instead, API functions are generally tested with unit and integration tests.
You'll need visibility into the API function calls themselves, so the testing will be white-box or at least grey-box. You should be ...

REST-Assured is one good option.
I have used it with Java. It's a really good option and gives you the flexibility to do a lot when it comes to API testing.
Refer to the below link for further details related to using Rest-Assured.

Writing an API test in Visual Studio can be done with:
NUnit or MSTest as your Test Runner
** NUnit and the TestAdapter are available on Nuget
An http client, like .Net's HttpClient
** This is in the System.Net namespace
(Optional) Json.Net for parsing responses
** Also avaiable on Nuget
Your test will look something like this:

I would approach with just refactoring the code to use restLibTwo. Here are few points on why I would do that:
Rest calls are just HTTP calls. Moving to another lib (for example RestAssured) would be likely motivated by surrounding functionality (like using gherkin notation or integrated json/xml parsing). So usually nobody tests REST with the lib that just ...

Start from learning REST API testing. REST is just an architectural paradigm, however most often it is implemented over HTTP protocol. So if you mean such the REST API then I would recommend to learn:
Some programming language basics
Learn how to interact with remote services using HTTP(s) protocols in that chosen programming language
Select some service to ...

You can take a look at Google HTTP Client Library for Java, that offers:
Pluggable HTTP transport abstraction that allows you to use any low-level library such as java.net.HttpURLConnection, Apache HTTP Client, or URL Fetch on Google App Engine.
You would need to write your own binding between Google HTTP Client API and restLibTwo. Note, however, there ...

I generally agree with @alexey-r... You should probably just re-write the code when the library changes.
Companies change libraries for a reason; new features, better features, streamlined configuration, etc. If you try to abstract too much you are:
Building your own API to connect with someone else's API
Making it difficult to take advantage of the ...

How to store code in a repository has many factors.
How many people are working on this project?
Who is responsible for testing (devs only, devs and qa)?
What testing methods are in use: unit tests, integration tests, UI tests?
Is there a difference between end-to-end and full stack testing?
Are you the only one working on this project and are responsible ...

Single Sign-On is a very broad term and testing it will much depend on how it has been actually implemented in your project.
In short Single Sign-On provides you a way to authenticate at one place (Identity Provider) and access multiple systems (Service Providers) without the need to re-authenticate.
Your SSO implementation may allow to authenticate at ...

There are a couple of areas that you will have to understand and provide focus in testing.
Understand the Purpose of the API that you are testing. What is it for? How is this going to be used? Answering these questions should provide you with test ideas related to your context.
Here are Sample Test ideas based on my personal experience in testing:

I worked on a reasonably similar stack and I would be looking at starting at the ‘lowest’ layer possible and work my way up to testing A.
So, in this case, I would be aiming to test B, C and D. Granted you’re doing some testing of another groups API, but if you’re not responsible for B, C and D, just devise tests to give you sufficient assurance that it ...

In a similar case, we went with writing our own very light weight framework.
Reasons are:
We were not using many of the features of Soap UI, so just to make Restful calls, Soap UI is an overkill
The paid version was costly for our need; extending the free version needed Groovy skills - Groovy was not a language our team was familiar with
Soap UI projects ...

It should normally be somewhere in the first response, either in response body, or headers, check the first response for anything looking like a token, extract it using a relevant JMeter PostProcessor, convert into a JMeter Variable and replace recorded hard-coded value with the variable coming from the PostProcessor. The process is known as correlation and ...

Yes, this should be very easy with Karate. I suggest you don't over-engineer tests and make 2 requests in your test. Save the response of the first request.
Now all you need to do is perform a match of the first response - that it is equal to the second response.
And because Karate allows you to set some fields of the "expected" JSON as #string or #notnull ...

Let's start from the bottom line- unless you revolutionize everything there will be no magic solutions.
Martin Fowler describes here the most common approach- test against a simplified copy of the external services, and occasionally verify that those copies behaves the same as the source.
The problem with this approach, beyond the obvious of ...

you are trying to make an element called 'Item IsKit =\"false\"'
it looks like you actually want to create an Element called Item with an attribute called IsKit.
Try this:

I believe Alexey and MivaScott have provided good advice here. I would like to add some additional thoughts on why coding to use any possible REST API client may not be the best idea.
Some of this will look blunt, but it is not a criticism of you.
I think what you're trying to code is an overcompensation for mistakes that people have made when designing ...

Should an automated testing project be created complex as much as
software being developed?
Probably, I would handle test-code the same as production-code. It should be as complex as it needs to be. It should be just as maintainable and understandable.

modules etc techniques?

Automation is about writing code.
It therefore can (and should) be as complicated or simple as need for the purpose it is needed.
Generally a more complex application, for instance one with many workflows, a mixture of JavaScript frameworks and long and detailed forms will generally require more effort and more programming approaches, such as the use of ...

Should software test automation projects echo the structure of the
application in test?
If "Echo" means to follow the same structure as the project from a code perspective (e.g. have package structure matching the application code) then no, not necessarily. If "Echo" means to model the application effectively - then yes, that can be very helpful.

Another option you could try is Google Voice (voice.google.com). This will give you a web interface to a phone number which is free for your first number.
I have used the app to test two factor authentication, so it should work for at least manual testing of your scenario.
Google allows you to have one number without charge, but you need to pay for any ...

Your data is not a valid JSON, you can check it yourself using i.e. online JSON formatter and validator
You syntax of combination of __eval() and __FileToString() functions is incorrect, you should wrap the __FileToString() function into the __eval() and you're doing the opposite thing:
${__eval(${__FileToString(${Json_request.txt},,)})}
