Testing Database Applications with Polygraph

Diverse applications implement read and write transactions using a data store. It is challenging to evaluate whether transactions that constitute an application provide strong consistency. It requires an end-to-end testing as an application may consist of several components that impact the consistency of data. Polygraph is a conceptual plug-n-play framework to quantify the amount of anomalies produced by an application. We show several use cases of Polygraph for two major application classes: e-commerce and cloud. One long-term objective of Polygraph is to reduce the cost and time required to test a data driven application, so that developers may focus more time and effort on applications' features and requirements.
