Integration testing of a REST API - Testing the ContentType header for the HTTP response

ContentTypeHeaderTest.java

@Test
public void givenRequestWithNoAcceptHeader_whenRequestIsExecuted_thenDefaultResponseContentTypeIsJson()
      throws ClientProtocolException, IOException{
   // Given
   String jsonMimeType = "application/json";
   HttpUriRequest request = new HttpGet( "https://api.github.com/users/eugenp" );
   
   // When
   HttpResponse response = this.httpClient.execute( request );
   
   // Then
   String mimeType = EntityUtils.getContentMimeType( response.getEntity() );
   assertEquals( jsonMimeType, mimeType );
}
