ResponseCodeTest.java

@Test
public void givenUserDoesNotExists_whenUserInfoIsRetrieved_then404IsReceived() 
      throws ClientProtocolException, IOException{
   // Given
   String name = randomAlphabetic( 8 );
   HttpUriRequest request = new HttpGet( "https://api.github.com/users/" + name );
   
   // When
   HttpResponse httpResponse = httpClient.execute( request );
   
   // Then
   RestAssert.assertResponseCodeIs( httpResponse, 404 );
}
