Worked on modernizing the test suite for the Shubhamsaboo/adk-samples repository by introducing asynchronous test support for the data science agent test suite. Migrated existing tests from unittest.TestCase to unittest.IsolatedAsyncioTestCase, enabling proper execution of asynchronous workflows within the testing framework. Updated both the test setup and individual test methods to accommodate async operations, which allows for more realistic and robust testing of asynchronous code paths. This work, implemented in Python and leveraging asynchronous programming techniques alongside unit testing best practices, established a foundation for improved test reliability and faster feedback cycles in continuous integration environments. No bugs were addressed.
