It seems to me that Druid's policy to prohibit static imports makes more harm than good in unit test code. It discourages the usage of static fixtures and encourages abstraction/inheritance, as I discussed here: https://github.com/apache/incubator-druid/pull/8564#issue-319753256, see "Refactoring of tests" section.
Alternative: allow only static imports from selected classes: Assert, Assertions, EasyMock, etc. IntelliJ's "Static import" inspection supports such fine configuration.
