Step 2: ⌨️ Coding

[ ] main/sweepai/agents/test_modify.py
Create main/sweepai/agents/test_modify.py with contents: Create a new file called test_modify.py in the main/sweepai/agents directory to hold the unit tests for modify.py.

Import the following at the top of the file:

unittest
unittest.mock.patch
modify, handle_function_call, generate_diffs from main.sweepai.agents.modify
ClonedRepo from main.sweepai.utils.github_utils
Any other needed test utilities

Define a test class:

class TestModify(unittest.TestCase):
    pass

Implement the following test methods in the TestModify class:

test_modify_success: Test the success scenario of the modify() function
- Use a mock ClonedRepo
- Provide a valid request and fcrs
- Assert that the correct modify_files_dict is returned
test_modify_no_changes: Test when modify() makes no changes to files
- Use a mock ClonedRepo
- Provide a request and fcrs that don't require any changes
- Assert that an empty modify_files_dict is returned
test_handle_function_call_submit_task: Test submitting a completed task
- Mock the generate_diffs() function
- Provide a function call with 'submit_task' tool name
- Assert the task is marked complete in fcrs and llm_state
test_handle_function_call_make_change: Test making a code change
- Provide a function call with 'make_change' tool name and valid parameters
- Assert the code change is correctly applied in modify_files_dict
test_generate_diffs: Test diff generation between original and modified files
- Provide sample original and modified file contents
- Assert the generated diff matches the expected output
[ ] main/sweepai/agents/modify.py

Create main/sweepai/agents/modify.py with contents: To make the modify module more testable, we should extract some of the nested logic into separate functions. This will make it easier to unit test individual pieces of functionality.

def handle_function_call( cloned_repo: ClonedRepo, function_call: AnthropicFunctionCall, modify_files_dict: dict[str, dict[str, str]], llm_state: dict, chat_logger_messages: list[dict[str, str]] | None = None, use_openai: bool = False, ) : # iterate through modify_files_dict and generate diffs llm_response = "" tool_name = function_call.function_name tool_call = function_call.function_parameters def handle_function_call( cloned_repo: ClonedRepo, function_call: AnthropicFunctionCall, modify_files_dict: dict[str, dict[str, str]], llm_state: dict, chat_logger_messages: list[dict[str, str]] | None = None, use_openai: bool = False, ) : llm_response = "" tool_name = function_call.function_name tool_call = function_call.function_parameters if tool_name == "submit_task": return handle_submit_task(modify_files_dict, llm_state, llm_response) elif tool_name == "no_tool_call": return handle_no_tool_call(use_openai, llm_response) elif tool_name == "make_change": return handle_make_change(cloned_repo, tool_call, modify_files_dict, llm_state, llm_response) def handle_submit_task(modify_files_dict, llm_state, llm_response): changes_made = generate_diffs(modify_files_dict) if changes_made: llm_response = "DONE" else: llm_state["done_counter"] += 1 if llm_state["done_counter"] > 3: llm_response = "DONE" else: llm_response = "ERROR\n\nNo changes were made. Please continue working on your task." for fcr in llm_state["fcrs"]: if not fcr.is_completed: fcr.is_completed = True break llm_state['current_task'] = render_current_task(llm_state["fcrs"]) # rerender the current task llm_response = f"SUCCESS\n\nThe previous task is now complete. Please move on to the next task. {llm_state['current_task']}" if all([fcr.is_completed for fcr in llm_state["fcrs"]]): llm_response = "DONE" return llm_response, modify_files_dict, llm_state def handle_no_tool_call(use_openai, llm_response): if use_openai: llm_response = NO_TOOL_CALL_PROMPT_OPENAI else: llm_response = NO_TOOL_CALL_PROMPT return llm_response, {}, {} def handle_make_change(cloned_repo, tool_call, modify_files_dict, llm_state, llm_response): # Existing make_change handling logic goes here ... return llm_response, modify_files_dict, llm_state

This change extracts the logic for handling 'submit_task', 'no_tool_call', and 'make_change' into separate functions. The main handle_function_call() now delegates to these extracted functions based on the tool_name. This will make it much easier to write focused unit tests for each tool handling scenario.
