Cloud enabled Testing

With proliferation of multiple development environments, operating systems, browsers, distributed user base world, testing of an application is becoming increasingly complex. N-Dimensional just seems inadequate when quantifying the testing space formed by new development environments.  In the past, we thought we could put our arms around the testing space. We felt like we could understand all the possible states and the resulting effect on our code path traversals. We would use our known black box testing methodologies (like boundary value analysis, equivalence class partitioning etc.) and could load test well beaten paths with our known testing tools.
