No. TestNG has explicit support for adding listeners from the launcher, JUnit
does not.
We could probably add something, but it wouldn't be a standard thing, it would
be a Gradle specific extension to JUnit. I don't think JUnit gives us the hooks
to mix a rule into every test. We'd have to invent something, perhaps
generating a Suite class dynamically that wraps all the test classes or
something like that.
