The ORMMA group recently released their web-based testing harness online for your ORMMA-ads: http://ormma-tester.appspot.com/
Just pick a device, the level of ORMMA-compliance (currently Level 1 and 2), and the device capabilities you want to test. Capabilities include:
- Screen Orientation
- Compass Heading
- Device Location
- Network Status
This is a super easy and fast way to make sure your ad is ready to be served into an ORMMA-compliant SDK.
