Parallel tests represent the next level in testing and involve relocating personnel to the alternate recovery site and implementing site activation procedures. The employees relocated to the site perform their disaster recovery responsibilities just as they would for an actual disaster.
The only difference is that operations at the main facility are not interrupted. That site retains full responsibility for conducting the day-to-day business of the organization.

Here are the five types of disaster recovery tests:
Paper test: Individuals read and annotate recovery plans.
Walkthrough test: Groups walk through plans to identify issues and changes.
Simulation: Groups go through a simulated disaster to identify whether emergency response plans are adequate.
Parallel test: Recovery systems are built/set up and tested to see if they can perform actual business transactions to support key processes. Primary systems still carry the full production workload.
Cutover test: Recovery systems are built/set up to assume the full production workload. You disconnect primary systems.
