Since migration-tests-commons updated its htmlunit version to 2.15, migration tests are failing. This is due to migration-tests-commons subclassing AbstractMagnoliaHtmlUnitTest and htmlunit 2.15 bringing some API breaking changes compared to the older version used by the bundles.
In particular:

• missing static constant for BrowserVersion FF 3_6
• methods previously part of WebClient no longer accessible directly, rather through WebClientOptions
• dependency on commons-lang3
• requires explicit dependency on xml-apis 1.4.01 because htmlunit
  DomElement implements an interface that was not in 1.3, hence not in the
  JDK
