Testing of these data systems have become very complex and requires a new approach. This paper highlights various aspects of Big Data Testing including:

• Complexity in testing Big Data systems

• Cloud based tools for testing Big Data cross various stages

• Simplification of test processes and visualization through dashboards

• Testing Big Data in the Agile/ DevOps
