test: retry count assertion on session invalidation #135

mcollovati · 2023-07-05T05:58:55Z

Description

Session context tests check the counter value hold by a session bean right after invalidating the Vaadin session. Since the counter is incremented in the PreDestroy hook, it may happen that when the test checks for the counter value, the callback has not yet been invoked. This change retries the counter check for at most on second, to preven ttest flakyness.

Fixes #126
