Can you use underscores in test methods?

Question

Java

For example,
addVote_timeValidAndVotePresent_updateVote()
methodName_stateUnderTest_expectedBehavior
Or is this against the convention and it's not allowed?

Methods should be verbs, in mixed case with the first letter lowercase, with the first letter of each internal word capitalized.

Yes, you can.

And using underscores outside of tests is not recommended.
