title: load properties in mule munit
body: <p>I have some placeholders in my flow. Values for these placeholders are specified in a properties file (in <strong>classpath</strong>). I am doing munit using java. Currently, these placeholders are not getting replaced by values in property file. Any idea how do I load this file while running munit?</p>
  
  <p>My munit is like this:</p>
  
  <pre><code>Class MyClass extends FunctionalMunitSuite{
  
      @Override
      protected String getConfigResources() {
  
          //try 1[gave give value pairs directly]: didnt worked
           System.getProperties().put("prop.key", "value");
  
           //try2[load prop files]:didn't worked
           prop.load(this.getClass().getResourceAsStream("mypropertyfile.properties"));
           System.setProperties(prop); 
      }
  
  }
  </code></pre>
