# Run Specific Tests Script
#
# Simple script to run specific test classes for fast iteration.
# Reads test classes from test-results/failed_tests.txt (auto-generated by run_all_tests.sh)
# or you can edit the file manually.
#
# Usage:
#   ./run_specific_tests.sh
#
# Configuration:
#   Option 1: Edit test-results/failed_tests.txt (recommended)
#   Option 2: Edit SPECIFIC_TESTS array in this script
#
# File format (test-results/failed_tests.txt):
#   One test class per line with full package path
#   Lines starting with # are comments
#   Example: code.api.v6_0_0.RateLimitsTest
#
# IMPORTANT: ScalaTest requires full package path!
#   - Must include: code.api.vX_X_X.TestClassName
#   - Do NOT use just "TestClassName"
#   - Do NOT include .scala extension
#
# How to find package path:
#   1. Find test file: obp-api/src/test/scala/code/api/v6_0_0/RateLimitsTest.scala
#   2. Package path: code.api.v6_0_0.RateLimitsTest
#
# Output:
#   - test-results/last_specific_run.log
#   - test-results/last_specific_run_summary.log
#
# Technical Note:
#   Uses Maven -Dsuites parameter (NOT -Dtest) because we use scalatest-maven-plugin
#   The -Dtest parameter is for surefire plugin and doesn't work with ScalaTest
