It is important to understand that once an API is published and others start using it, we need to make sure that future changes do not break the usage for those who did not update their clients accordingly.
For an internal application, this kind of testing will usually run as a late step in a Continuous Integration process, consuming the REST API after it has already been deployed. When testing a REST resource, there are usually a few orthogonal responsibilities the tests should focus on: the HTTP response code; other HTTP headers in the response Like most Spring Getting Started guides, you can start from scratch and complete each step or you can bypass basic setup steps that are already familiar to you.Either way, you end up with working code.

Apache HttpClient is a robust and complete solution Java library to perform HTTP operations, including RESTful service. In this tutorial, we show you how to create a RESTful Java client with Apache HttpClient, to perform a “GET” and “POST” request. REST guidelines suggest using a specific HTTP method on a specific type of call made to the server (though technically it is possible to violate this guideline, yet it is highly discouraged). Use below-given information to find a suitable HTTP method for the action performed by API.

The 301 status code indicates that the REST API’s resource model has been significantly redesigned, and a new permanent URI has been assigned to the client’s requested resource. The REST API should specify the new URI in the response’s Location header, and all future requests should be directed to the given URI. Making use of a REST API obviously involves using the Internet. However, Android applications can access the Internet only if they have the android.permission.INTERNET permission. Therefore, before you start writing any networking code, you must make sure that the following uses-permission tag is present in your project's manifest file:
