Wind River Framework for Automated Software Testing (FAST) Wind River Framework for Automated complicate the test and validation developer or quality assurance (QA) Software Testing (FAST) was developed process. To properly validate the engineer needs to adapt tests to run on to help customers overcome the distribution, tests for the following are each device. Each target may have a challenges of testing large software needed: unique hardware configuration, distributions for mobile devices. FAST Requirements peripherals, file storage systems, and so provides a system for combining Performance on.
