# Run the test suite and report the JUnit XML, not just the exit code.

# A green `test` task does not prove tests ran (see AGENTS.md), so this always
# prints tests/failures/errors per suite and dumps failure messages.
#
# Two concurrent Gradle invocations (e.g. an editor/agent running tests in the
# background at the same time) fight over build/test-results and the loser dies
# with `java.io.EOFException` or a missing in-progress-results bin. That is an
# infrastructure failure, not a test failure, so it is retried once.
#
# Usage: ./jaitest [gradle args...]      e.g. ./jaitest --tests '*Lexer*'
