By ensuring adequate functional coverage, End-to-End (E2E) testing is a key enabling factor of continuous integration. This is even more true for web applications, where automated E2E testing is the only way to exercise the full stack used to create a modern application. The test code used for web testing usually relies on DOM locators, often...

The state space of Android apps is huge, and its thorough exploration during testing remains a significant challenge. The best exploration strategy is highly dependent on the features of the app under test. Reinforcement Learning (RL) is a machine learning technique that learns the optimal strategy to solve a task by trial and error, guided by...

Existing web test generators derive test paths from a navigational model of the web application, completed with either manually or randomly generated input values. However, manual test data selection is costly, while random generation often results in infeasible input sequences, which are rejected by the application under test. Random and...

Automated web testing is an appealing option, especially when continuous testing practices are adopted. However, web test cases are known to be fragile and to break easily when a web application evolves. The Page Object (PO) design pattern addresses such problem by providing a layer of indirection that decouples test cases from the internals of...
