(grails-core) 24/33: test(h7): expand PredicateGenerator and GrailsNativeGenerator coverage
This is an automated email from the ASF dual-hosted git repository.
borinquenkid pushed a commit to branch 8.0.x-hibernate7-dev
in repository https://gitbox.apache.org/repos/asf/grails-core.git
commit cc9a4e294073838c469acab5abe311cf842d7f62
Author: Walter Duque de Estrada <wb...@mac.com>
AuthorDate: Tue Apr 7 11:46:25 2026 -0500
test(h7): expand PredicateGenerator and GrailsNativeGenerator coverage
- PredicateGeneratorSpec: add 7 new tests covering DistinctProjection, NotExists,
IsNull/IsNotNull, IsEmpty/IsNotEmpty, NotEqualsProperty,
LessThan/GreaterThan property comparisons, and unsupported criterion exception
- GrailsNativeGeneratorSpec: add non-SSG delegate branch test to cover the
instanceof false path in generate()
- Mark X: GrailsNativeGenerator, PredicateGenerator in JACOCO_COVERAGE_VIOLATIONS.md
