Updating systems assembled from components demand a careful treatment due to stability risks. Replacement components must be properly evaluated to identify the required similar behaviour. Our proposal complements the regular compatibility analysis with black-box testing criteria to reinforce reliability. The aim is to analyze functions of data transformation encapsulated on components, i.e. their behaviour. This complies with the observability testing metric. A Component Behaviour Test Suite is built concerning the integration level to be later applied on candidate upgrades. The approach is supported through a tool developed on our group, testooj, which is focused on Java components.
