# Conducting Testing

Once the default authentication profile is configured, you can test the integration using the test application provided by Cirrus Identity. 


## Prepare Your Endpoint (DNS Add-On) {#prepare-your-endpoint-dns-add-on}


If you have enabled the DNS Add-On, you will need to modify your local hosts file to point the FQDN to the IP address provided by your implementation lead. 

- On Mac computers, this file can be found at `/etc/hosts`. 
- On Windows computers, it is typically found at `C:\Windows\System32\drivers\etc\hosts`.

If you're unfamiliar with editing your hosts file, [Rackspace provides an excellent primer](https://docs.rackspace.com/docs/modify-your-hosts-file).


## Using Your Cirrus Test Application {#using-your-cirrus-test-application}


The testing URL is unique for your Cirrus Bridge implementation and will be provided to you by your implementation lead. **In a private browser/incognito window**, navigate to the test URL.

- Example: `https://athena-bridge.cirrusidentity.com/demo.php`



1. **Click the first link.**

   This should be "Test Authenticating With Cirrus".

2. **Authenticate and review event details.**

   You should be prompted for MFA if you have enabled it.

3. **Verify your attribute values.**

   AuthnContext should be `https://refeds.org/profile/mfa`, and NameID & format are as expected.





> [!NOTE]
> The default NameID format is usually transient with a random value for the NameID itself.
