title: How Validation can happen for a Message Toast popup text in OPA5 test Framework?
body: <p>Here is my code :</p>
  
  <pre><code>function() {
       this.waitFor({
           matchers: function() {
               console.log(jQuery(".sapMMessageToast").text());
               return (jQuery(".sapMMessageToast").text() === "Hello World");
           },
           success: function() {
               Opa5.assert.ok(true, "Pop Message Toast is coming Successfully");
           },
  
           errorMessage: "No Toast message detected!"
       });
  }
  </code></pre>
  
  <hr>
  
  <p>Output :-</p>
  
  <p>Getting Error as :- </p>
  
  <p>No Toast message detected!
  Opa timeout
  This is what Opa logged:
  all results were filtered out by the matchers - skipping the check -  sap.ui.test.pipelines.MatcherPipeline

  Expected:<br>

  false

  <p>So here <code>jQuery(".sapMMessageToast").text()</code> statement returning <code>""</code> , instead of <code>Hello World</code> (Actual Message popup by app), so control is going to error condition . </p>
