The paper follows the evolution of the PGR - Upload project undertaken during my internship at Alten Italia. The subject of the discussion is the testing process carried out for a banking institution's application in which the focus is the implementation of the Upload functionality, an integration to the PGR application used for the management of retail customers' credits with reference to non- performing loans, through which the user will be able to carry out massive actions, centralising the process and the monitoring of requests. The project consists of 179 tests, including both front-end and back-end tests. At the end of the test execution phase, data on the outcome of the tests are collected in company reports and analysed using appropriate KPIs.
