Proof's elegant out-of-the-box feature with its proprietary algorithms to achieve high parallelism. In simple words, you can run your tests in parallel from the same application with zero effort. You can further organize your test suites (Collection of test cases) into execution sets by drag-and-drop, select browser of choice, add optional data sets (i.e. Data Driven Testing) and provide the application under test URL. At this point, you either schedule this execution-set to run at a particular time or ask your build system to invoke it for you with our RESTful API. This enables you to run thousands of tests and get results within couple of hours and forget about building an infrastructure, framework, and operations which will take at least months if not years. We use famous cloud providers such as Rackspace and Amazon EC2 to achieve parallel execution in a small time window. All tests will be run on an individual virtual machine mimicking production environment which real users of your system will use.
