ZIO Test writes a report into target/test-reports-zio/output.json; this location is appropriate when running with sbt - and completely out of place for other build tools (e.g. Gradle).
Please add command line arguments (in zio.test.TestArgs) that allow either relocating the report or suppressing it altogether - or both (the only other sbt-equipped test framework that prints test reports - specs2 - allows both), so that build tools running ZIO Test via its sbt.testing.Framework implementation will be able to adjust the behavior.
Thanks!!
