title: Do Any JavaScript Test Frameworks Support ES Modules
body: <p>Do any test frameworks support tests that use the new ES Modules syntax? I have a JS application which heavily uses <code>.mjs</code> files with ES Modules.  I tried Jest and Jasmine, both of which throw errors when I try to write run tests for my app.  I need to test this file:</p>
  
  <p><strong>math.mjs</strong></p>
  
  <pre><code>export function add(a, b) {
    return a + b;
  }
  </code></pre>
