ATAAS2016 - Performance testing iot a case study rajat tahem

Performance testing in the IoT world In the day and age when all devices are interconnected with each other there are numerous challenges. We need to be able to identify the various bottlenecks and establish bechmarks for the devices talking to each other. Also, how fast or slow the devices are when they interact with each other. Also, it is seen that there is not enough time for resting or tuning. Also, we need to be able to find out the right set of test data that we would need for the tests. It is also seen as hat typically testers are involved very late in the game but when there are numerous devices talking to each other it’s vital to start early. Through this session we will look at the various challenges in the IoT world with regards to performance testingand how we got around the challenges.
