# Installed but not seeing errors. How do I trigger an error?

I just signed up and installed on my angularjs site but I’m not seeing any errors. Is there a way to trigger an error so I know it’s installed correctly?

Once you’ve configured RavenJS, you should be able to test with Raven.captureException(message);

Thanks! That worked great. I see the error I generated. For some reason I don’t see this actual error though:

raven.js:132 ReferenceError: MathJax is not defined
