How are apex tests run before a service upgrade?

Before each major service upgrade, Salesforce runs all Apex tests on your behalf through a process called Apex Hammer. The Hammer process runs in the current version and next release and compares the test results. This process ensures that the behavior in your custom code hasn’t been altered as a result of service upgrades.
