Paul King commented on GROOVY-11721:
------------------------------------
Another way to go if you can use Groovy 5 is JEP 512 compatible scripts which
don't require @Field (acknowledging that the unused main method while harmless
is a little ugly):
{code:language=groovy|title=example-test.groovy}
import org.junit.jupiter.api.*
def foo = 'Foo'
def bar = 'Bar'
@Test
void 'can access fields'() {
assert foo + bar == 'FooBar'
}
def main() { } // unused
{code}
> @groovy.transform.Field to annotate a script class

> We use undeclared Groovy Scripts together with JUnit for writing unit tests
> because it supports sentences as method names and doesn’t impose restrictions
> on the file name (we need the test script name to match the name of the YAML
> file being tested). This solution works very well; the only downside is that
> in order to use annotations on a field, such as [email protected]_, we
> also need to use [email protected]_, since those annotations typically
> don’t have target = LOCAL_VARIABLE. It would be convenient if _@Field_ could
> be placed on the script class (with _@Inherited_ to support a base script)
> and be automatically applied to all local variables in the script
