title: Cypress failing test due to CORS?
body: <p>I have a simple test that fails due to <code>CORS</code> and I'm unsure how to fix it:</p>
  <pre><code>    it(&quot;Visits home&quot;, () =&gt; {
          cy.visit(&quot;http://localhost:3000&quot;);
      });
  </code></pre>
  <p>This is the error:</p>
  <pre><code>  1) Test
         Visits the home page:
       SecurityError: Blocked a frame with origin &quot;http://localhost:3000&quot; from accessing a cross-origin frame.
  </code></pre>
