[Ellipsis] Agent tests

[ellipsis-dev]

Summary:

⚠️ We couldn't build/test your project to verify our changes. Add a Dockerfile to significantly improve code quality.

Issue: #15

Implementation:

1. Create a new test file for config.py
   • Create a new file in the test folder named test_config.py. This file will contain all the tests for the functions in config.py. Use the unittest module to structure your tests. Start by importing the necessary modules and creating a new test case class.
2. Create tests for fetch_config function
   • In the test_config.py file, create a test for the fetch_config function. Use the unittest.mock module to create a mock Google Cloud Storage bucket and blob. Test that the function correctly fetches the blob and returns the updated time. Also, test the case where the blob does not exist and the function should return None.
3. Create tests for get_module_filepath function
   • In the test_config.py file, create a test for the get_module_filepath function. Create a mock file and test that the function correctly returns the full file path of the mock file. Also, test the case where the file does not exist and the function should raise an error.
4. Create tests for load_config function
   • In the test_config.py file, create a test for the load_config function. Create a mock configuration file and test that the function correctly loads the file. Also, test the case where the file does not exist and the function should raise an error. Additionally, test the case where the environment variable is not set and the function should raise an error.
5. Create tests for load_config_key function
   • In the test_config.py file, create a test for the load_config_key function. Create a mock configuration file and test that the function correctly loads a specific key from the file. Also, test the case where the key does not exist in the configuration file and the function should raise an error.

Report:

Step	Result	Details
1	✅	Create a new test file for config.py Created a new test file 'test_config.py' in the '/sunholo/tests/' directory. The file currently imports the necessary modules and has a test case class named 'TestConfig'.
2	✅	Create tests for fetch_config function Added a test for the fetch_config function in the test_config.py file. The test uses mock objects to simulate a Google Cloud Storage bucket and blob, and tests that the function correctly fetches the blob and returns the updated time. It also tests the case where the blob does not exist and the function should return None.
3	✅	Create tests for get_module_filepath function Added a test for the get_module_filepath function in the test_config.py file. The test uses a mock file and tests that the function correctly returns the full file path of the mock file. It also tests the case where the file does not exist and the function should raise an error.
4	✅	Create tests for load_config function Added a test for the load_config function in the test_config.py file. The test uses a mock configuration file and tests that the function correctly loads the file. It also tests the cases where the file does not exist and the environment variable is not set.
5	✅	Create tests for load_config_key function Added a test for the load_config_key function in the test_config.py file. The test uses a mock configuration file and tests that the function correctly loads a specific key from the file. It also tests the case where the key does not exist in the configuration file and the function should raise an error.
