title: Jasmine: Testing static function in another class
body: <p>Assuming i have a static class and a normal class as below.</p>
  
  <pre><code>class StaticClass {
    static staticFunction() { 
      console.log('Static function called.');
    }
  }
  
  class NormalClass {
    normalFunction() { 
      StaticCLass.staticFunction();
    }
  }
  </code></pre>
  
  <p>How do I test that the static function is called when <code>normalFunction()</code> is called?</p>
