Summary of Changes

Hello @twishabansal, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly refactors the continuous integration (CI) testing framework for quickstart examples. It consolidates the previously separate language-specific test execution scripts (Go, JavaScript, Python) into a single, parameterized shell script. This change aims to reduce redundancy, simplify maintenance, and provide a more consistent and robust testing environment for all quickstart examples.

Highlights

• Unified Test Runner: Replaced separate language-specific test runner scripts (run_go_tests.sh, run_js_tests.sh, run_py_tests.sh) with a single, universal run_tests.sh script.
• Dynamic Language Support: The new run_tests.sh script dynamically handles test execution for Python, JavaScript, and Go based on environment variables like TARGET_LANG and AGENT_FILE_PATTERN, reducing code duplication.
• Cloudbuild Configuration Updates: Modified go.integration.cloudbuild.yaml, js.integration.cloudbuild.yaml, and py.integration.cloudbuild.yaml files to invoke the new run_tests.sh and pass necessary language-specific configuration via environment variables.
• Improved Health Checks and Logging: The universal runner includes enhanced health checks and logging for the Cloud SQL Proxy and Toolbox server startup, making the testing process more robust and easier to debug.
• Flexible Test Discovery: The new runner incorporates logic to discover and execute native test files (e.g., *test.py, *test.js) or directly run the agent file if no specific test file is found within a sample directory.

Changelog

• .ci/quickstart_test/go.integration.cloudbuild.yaml
  • Updated the build step to call the new run_tests.sh script.
  • Configured new environment variables (TARGET_ROOT, TARGET_LANG, TABLE_NAME, SQL_FILE, AGENT_FILE_PATTERN) for Go-specific test execution.
• .ci/quickstart_test/js.integration.cloudbuild.yaml
  • Updated the build step to call the new run_tests.sh script.
  • Configured new environment variables (TARGET_ROOT, TARGET_LANG, TABLE_NAME, SQL_FILE, AGENT_FILE_PATTERN) for JavaScript-specific test execution.
• .ci/quickstart_test/py.integration.cloudbuild.yaml
  • Updated the build step to call the new run_tests.sh script.
  • Configured new environment variables (TARGET_ROOT, TARGET_LANG, TABLE_NAME, SQL_FILE, AGENT_FILE_PATTERN) for Python-specific test execution.
• .ci/quickstart_test/run_go_tests.sh
  • Removed, as its functionality is now integrated into the universal run_tests.sh script.
• .ci/quickstart_test/run_js_tests.sh
  • Removed, as its functionality is now integrated into the universal run_tests.sh script.
• .ci/quickstart_test/run_py_tests.sh
  • Removed, as its functionality is now integrated into the universal run_tests.sh script.
• .ci/quickstart_test/run_tests.sh
  • Added a new universal shell script responsible for setting up the test environment.
  • Includes logic to start services (Cloud SQL Proxy, Toolbox) with improved health checks and logging.
  • Executes language-specific quickstart tests (Python, JS, Go) based on provided environment variables.

Code Review

This pull request successfully consolidates the language-specific quickstart test runners into a single, universal run_tests.sh script. The cloudbuild.yaml files have been updated to utilize this new script and pass the necessary language-specific configurations. This refactoring improves maintainability by centralizing the test execution logic. However, there are a few issues identified regarding cleanup commands, the Go test implementation, and a future copyright year that should be addressed.

Can we trigger a run for all go, js, and py quickstart tests in this PR to test the changes? Otherwise LGTM :)

It is not possible to run these triggers directly yet because they use the run_test script files in main (not pushed yet). However, I have used the gcloud builds submit command to test the changes in these PR by submitting the build to google cloud. I think that should work for testing the local changes. WDYT?

LGTM :)
