The product time to market must be fast for quick gathering feedback from the user. DevOps brings the continuous practice to improve software development process on both continuous integration and continuous delivery. In continuous processes, software testing is the most time-consuming part which significant for overall process especially graphic user interface or GUI. Several techniques can reduce GUI testing time such as a distributed testing which is help UI testing running in parallel on a distributed machine. By running distributed GUI testing initially without experience or knowledge from an expert lead to the un-optimized speed of running test or even the future problem such as an unpredictable number of worker, the bottleneck of the worker node. This paper has purpose the Atom-Task precondition technique, the technique for filtering the test before running the parallel testing process to optimize the testing time and avoiding worker bottleneck problem and also remain an ability to scale the worker process for desired testing time with predictable resource for large-scale testing in the distributed environment.Mahidol UniversityComputer ScienceConference PaperSCOPUS10.1109/ICSEC.2017.8443913
