title: Check @RequestMapping - unit test
body: <p>I have a task to do:
  This controller should have its own unit test to verify, that <code>@RequestMapping</code> is set to <code>/ api / report / article_pairs</code>.</p>
  
  <pre><code> @RestController
   @RequestMapping("/api/report/article_pairs")
   public class ArticlePairsController extends ReportController&lt;ArticlePairs&gt;{
  
  public ArticlePairsController(HttpReportExecutor&lt;ArticlePairs&gt; articlePairs) {
      super(articlePairs);
  }
  
  @PostMapping()
  public HttpEntity&lt;Void&gt; proceed(@RequestBody ArticlePairs articlePairs) {
  
      articlePairs.setDbconn(schemaName + "." + CENTRALA);
  
      return executeReport(articlePairs, "report.articlePairs");
    }
  }
  </code></pre>
  
  <p>If someone in the future would change this value, a unit test should show this.</p>
  
  <p>Unit testing is a new issue for me, so could I ask for some advice? thank you in advance.</p>
