RestSharp Components

 RestSharp is a comprehensive open-source HTTP client library that supports a wide range of Dot Net technologies. It can be used to build robust applications by making it simple to interface with public APIs and quickly access data without having to deal with the complexities of dealing with raw HTTP requests.

RestClient:

RestClient acts as a conduit between the request and the server, allowing the response to be obtained via the HTTP methods from the server.

·         public static RestClient client;

·         Client=new RestClient(“http://baseurl.com/”);

RestRequest:

           RestRequest allows you to create a request that includes a header, parameters, and so on.

·         public static RestRequest restRequest;

·         restRequest=new RestRequest (Method. GET);

·         restRequest.AddHeader(“Accept”,” application/json”);

Handling Request:

• RestRequest generates a new request to the specified URL.
• The parameter AddParameter will be added to the request.
• Using request, AddHeader, you can easily add an HTTP header to the request you've created.
• Request can be used to replace a taken in a request. This will substitute AddUrlSegment for the matching token in the request.
• Use the command client execute to carry out the request (request). Your data can also be parsed using the response object.

Execute:

            var content=client.Execute(restRequest).content;

            Here, we use client to execute. Execute by passing a reference to the request and receiving a response in the form of content.

Method of execution:

            To execute the API request from the RestSharp client, we must use the simple execute method, but this is not the only option. There are numerous overloaded Execute methods available, for example.

• Execute
• Execute<>(generic)
• ExecuteAsGet
• ExecuteAsGet<>
• ExecuteAsPost
• ExecuteAsPost<>
• ExecuteAsync
• ExecuteAsync<.>
• ExecuteAsynGet

RestResponse:

           RestResponse is a response that comes from the server in various formats such as JSON, XML, and so on.

            var response=client.Execute(restRequest);

Features of RestSharp:

• The API returns XML, which is detected and de-serialized to the call object using the default xmlDeserializer.
• A RestRequest is sent as a GET HTTP request by default. You can change this by setting the RestRequest method property or specifying the method in the function Object() { [native code] } when creating an instance (covered below).
• The value of UrlSegment parameters is injected into the URL based on a matching token name in the Resource property value.

 

Nunit Framework:

Nunit is a Microsoft.Net unit testing framework that is open source. It performs the same function as Junit in Java and is one of many programmes in the Xunit family.

Features:

• Tests can be done from a console runner, within Visual Studio via a Test Connector, or via third-party runners.
• Tests can be run concurrently.
• There is a lot of support for data-driven tests.
• Supports a variety of platforms, including.
• Net core, Xamarin Mobile, Compact Framework, and Silverlight are examples of programming languages.
• Every test case can be assigned to one or more categories, allowing for selective execution.
