How to create Rest API test framework using Rest Assured Java library

• Maven Dependency to add,
  <!-- https://mvnrepository.com/artifact/io.rest-assured/rest-assured -->
<dependency>
<groupId>io.rest-assured</groupId>
<artifactId>rest-assured</artifactId>
<version>5.0.0</version>
<scope>test</scope>
</dependency>
	
• RestAssured.uri = "" // to specify the basic URL of the API

• Basic building blocks of Rest Assured is - given(), when(), then()

• Values that can be provided in the given block,
	    Response res = given().
            baseUri("https://reqres.in/api/users?page=2").
            contentType(ContentType.JSON).
            
• To print the response body as string,
            System.out.println(res.getBody().asString());

• To specify particular header value when sending the request
	   Header header = new Header("key","value");
	   RequestSpecification requestSpecification = given().header(header);
			
• To validate response content type,
	   response.then().contentType(ContentType.JSON);

• To get log when response is being fetched,
           response.then().log().all();

• To validate a particular item from the response body and status code,
           Assert.assertEquals(res.statusCode(),200);
