Update concurrent tests to JUnit Jupiter
Upgrade the tests in the concurrent package to use JUnit Jupiter as part of
the effort to remove the dependency on the Vintage Engine.
While most of these changes are drop-in replacements with no functional
benefit, there are some non-obvious changes worth mentioning.
Unlike `org.junit.Test`, `org.junit.jupiter.api.Test` does not have an
`expected` argument. Instead, an explicit call to
`org.junit.jupiter.api.Assertions.assertThrows` is used. This call allows the
test to pinpoint the exact statement that is expected to throw the exception
and allows making the tests a bit stricter by preventing
false-positives that could occur if the setup code would throw the expected
exception instead of the statement that was supposed to throw it.
Another notable change was performed in `MemoizerTest`.
JUnit Jupiter does not support JUnit 4's runners, and EasyMock has no
equivalent `@Extension`, so a setup method was added and the mock was
explicitly initialized.
It's also worth noting this is a minimal patch for migrating the package's
tests to Jupiter. There are several tests that can be made more elegant with
Jupiter's new features, but that work is left
for subsequent patches.
