Summary of Changes
Hello @MervinPraison, 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 enhances the testing coverage for PraisonAI's sequential tool calling capabilities. It introduces a new, comprehensive suite of mock tests designed to validate the robust and accurate execution of tool sequences, ensuring that the system behaves as expected under various conditions and with different large language model providers.
Highlights
- New Test Suite: A dedicated test file
test_sequential_tool_calling.pyhas been added to comprehensively test the sequential tool calling feature within PraisonAI. - Robust Mocking Infrastructure: Introduces a
MockLLMResponseclass and mock tools to simulate realistic LLM interactions and tool executions, ensuring isolated and reliable testing of the agent's behavior. - Extensive Scenario Coverage: The new tests cover a wide range of sequential tool calling scenarios, including basic multi-tool sequences, tool dependencies, streaming responses, error handling, context preservation, and complex argument passing.
- Multi-Provider Compatibility: Includes parameterized tests to verify that sequential tool calling functions correctly across different LLM providers such as OpenAI, Gemini, Ollama, and Anthropic, accounting for their specific tool call formats.

Code Review
This pull request adds a comprehensive suite of mock tests for sequential tool calling, covering various providers and scenarios. The tests are thorough and cover many important cases. My review focuses on improving the structure, correctness, and maintainability of these new tests. Key feedback includes fixing a critical structural issue with test method placement, correcting inconsistencies in mock data, improving the accuracy of the streaming test mock, and simplifying the test setup for better readability. Addressing these points will make the test suite more robust and easier to maintain.

There was a problem hiding this comment.
This test method (test_sequential_with_context_preservation), and the ones following it, are defined as instance methods (they accept self) but are located outside the TestSequentialToolCalling class scope. This is a structural error that will cause pytest to fail when running these tests.
These methods should be moved inside the TestSequentialToolCalling class and indented correctly to be part of it. The standalone test function test_sequential_with_different_providers should either be moved to the end of the file, or these methods should be placed before it within the class definition.

The create_streaming_response helper function doesn't accurately mock a streaming response. A streaming call to litellm.completion returns a generator that yields response chunks, but this implementation returns a list containing a single chunk. This means the test isn't properly verifying the agent's ability to handle a stream of data.
To correctly test streaming, the mock should return a generator. Here's an example of how you could implement this:
def create_streaming_generator(content_parts):
# Using the same mock chunk structure for simplicity
class MockDelta: ...
class MockStreamChoice: ...
class MockStreamChunk: ...
def generator():
for part in content_parts:
yield MockStreamChunk(part)
return generator()
# In your test:
responses = [
create_streaming_generator(["I'll get ", "the stock ", "price first."]),
# ... other responses

There's an inconsistency in how the arguments for Ollama tool calls are mocked. Here, the arguments are a dictionary, but in test_sequential_with_ollama (line 378), they are a JSON string, with a comment explicitly stating that's the format for Ollama.
To ensure the tests are consistent and reliable, the mock data should match the expected format in all relevant tests. Based on the other test, this should likely be a JSON string.

Modifying sys.path with relative paths is generally discouraged as it can make tests brittle and dependent on the directory from which they are run. A more robust industry practice is to install the project in an editable mode (pip install -e .) which makes the package available on sys.path without manual manipulation.
If path manipulation is unavoidable, consider constructing absolute paths to make it more reliable:
import os
import sys
# Get the absolute path to the project root
project_root = os.path.abspath(os.path.join(os.path.dirname(__file__), '../../..'))
sys.path.insert(0, project_root)
# Get the absolute path to the agents directory
agents_path = os.path.abspath(os.path.join(os.path.dirname(__file__), '../../../../praisonai-agents'))

The MockLLMResponse class and its nested helper classes are quite verbose for creating mock objects. Python's unittest.mock.MagicMock is designed for this purpose and can significantly simplify this setup, making the tests easier to read and maintain.
Here's an example of how you could simplify this using MagicMock:
from unittest.mock import MagicMock
def create_tool_call_response(tool_calls, content=""):
mock_response = MagicMock()
# Configure the mock to have the desired structure and values
mock_response.choices = [MagicMock()]
mock_response.choices[0].message.content = content
mock_response.choices[0].message.tool_calls = tool_calls
return mock_response
def create_text_response(content):
return create_tool_call_response([], content)
# Usage in a test:
responses = [
create_tool_call_response([...], "Some content")
]This approach is more idiomatic and leverages the standard library's powerful mocking capabilities.
| try: | ||
| result = agent.start("Double the number 5 using the flaky tool.") | ||
| # The test might fail due to error handling implementation | ||
| # This is expected and shows where the implementation needs work | ||
| except ConnectionError: | ||
| # This is expected if retry logic is not implemented | ||
| pass |
There was a problem hiding this comment.
This test for tool retry logic doesn't effectively verify the retry mechanism. The try...except ConnectionError: pass block will always pass as long as the tool's first call fails, which it is designed to do. It doesn't confirm that a retry was actually attempted or that the agent recovered successfully.
The comments suggest the retry logic may not be implemented yet. If so, this test should be marked with @pytest.mark.xfail(reason="Retry logic not yet implemented") to make its purpose clear.
If the retry logic is expected to work, the test should assert that the tool was called multiple times and that the final result is correct, without catching the exception.

Bug: Test Discovery and Tool Mismatch Issues
Three test methods (test_sequential_with_context_preservation, test_sequential_with_complex_arguments, and test_sequential_tool_retry_on_error) are incorrectly indented. They are nested inside the test_sequential_with_different_providers function, preventing pytest from discovering them as class methods.
Additionally, within test_sequential_with_context_preservation, the mock LLM responses reference get_stock_price and multiply, but the agent is initialized with track_stock_price and track_multiply, causing a tool mismatch.

Bug: Inconsistent Tool Argument Formats in Tests
Inconsistent argument format for Ollama tool calls in tests. While the dedicated Ollama test and other parts of the file consistently use JSON strings for tool arguments, the parametrized test for different providers uses a raw Python dictionary. This inconsistency may lead to inaccurate mock behavior or test failures.

💡 Verification agent
🧩 Analysis chain
Verify Ollama tool call argument format consistency.
There's an inconsistency in how Ollama tool arguments are formatted. In this test (line 378), arguments are JSON strings, but in the parameterized test (line 476), they're Python dicts. Please verify which format is correct for Ollama.
🌐 Web query:
What is the correct format for tool call arguments when using Ollama with LiteLLM? Should arguments be JSON strings or Python dictionaries?
💡 Result:
When using Ollama with LiteLLM, the correct format for tool call arguments is to provide them as JSON strings rather than as Python dictionaries. This means you should serialize your arguments into JSON format before passing them to the tool calls.
Use JSON strings for Ollama tool call arguments
Ensure all Ollama tool calls serialize their arguments as JSON strings (not Python dicts). The sequential test is already correct; update the parameterized case:
• File: src/praisonai/tests/unit/test_sequential_tool_calling.py
– Lines ~476–477: wrap the dict in json.dumps(...)
Example diff:
- {"function": {"name": "get_stock_price", "arguments": {"company_name": "Apple"}}}
+ {"function": {"name": "get_stock_price", "arguments": json.dumps({"company_name": "Apple"})}}Committable suggestion skipped: line range outside the PR's diff.
🤖 Prompt for AI Agents
In src/praisonai/tests/unit/test_sequential_tool_calling.py around lines 476 to
477, the parameterized test case for Ollama tool calls currently passes Python
dicts directly as arguments. To fix this, wrap the arguments dict in
json.dumps(...) to serialize it as a JSON string, matching the Ollama format
used in the sequential test. This ensures consistency and correctness in the
test inputs.

🛠️ Refactor suggestion
Test doesn't verify complex argument handling.
The test defines a process_data tool with complex arguments but doesn't verify that the tool is actually called with the expected complex data structures.
Consider enhancing the test to verify complex argument handling:
# Track actual tool calls
tool_calls = []
def process_data(data: dict, options: dict) -> dict:
"""Process complex data structure"""
tool_calls.append((data, options))
return {
"processed": True,
"input_keys": list(data.keys()),
"option_count": len(options)
}
# ... rest of the test setup ...
# After execution, verify the tool was called with expected complex arguments
assert len(tool_calls) > 0
assert isinstance(tool_calls[0][0], dict) # data argument
assert isinstance(tool_calls[0][1], dict) # options argument🤖 Prompt for AI Agents

334, the test defines a process_data tool with complex arguments but does not
verify that the tool is called with the expected complex data structures. To fix
this, modify the process_data function to append its input arguments to a list
for tracking calls, then after executing the agent.chat call, add assertions to
check that the tool was called at least once and that the arguments passed are
dictionaries, confirming proper handling of complex arguments.

Critical: All tests are mocking the wrong component.
The tests are mocking praisonaiagents.llm.openai_client.OpenAIClient, but based on past review comments and the test failures, the actual implementation uses litellm.completion. This explains why the mock call counts are 0 or 1 instead of the expected values.
All test methods need to be updated to mock litellm.completion instead.
Example fix for the decorator:
-@patch('praisonaiagents.llm.openai_client.OpenAIClient')
+@patch('litellm.completion')The mock setup and assertions will also need to be adjusted to match the litellm interface.

Fix incorrect error handling expectation.
The test expects the agent to return None on error, but based on past review comments, it should raise a ValueError.

Use ChatCompletion dataclass for mocks instead of nested MagicMock
The chat_completion_with_tools helper returns a ChatCompletion object (with a list of Choice whose .message is a ChatCompletionMessage), not a bare MagicMock. Please update the test in src/praisonai/tests/unit/test_sequential_tool_calling.py (lines 55–59) to construct a real ChatCompletion:
• Import the types at the top of the file:
from praisonaiagents.llm.openai_client import (
ChatCompletion,
Choice,
ChatCompletionMessage,
)• Replace your existing mock with:
- mock_response = MagicMock()
- mock_response.choices = [MagicMock()]
- mock_response.choices[0].message.content = (
- "The stock price of Google is 100, and when multiplied by 2, the result is 200."
- )
+ mock_response = ChatCompletion(
+ id="test-id",
+ choices=[
+ Choice(
+ finish_reason=None,
+ index=0,
+ message=ChatCompletionMessage(
+ content=(
+ "The stock price of Google is 100, "
+ "and when multiplied by 2, the result is 200."
+ ),
+ role="assistant",
+ ),
+ )
+ ],
+ created=0,
+ model="test-model",
+ )This aligns the mock with the actual return type of chat_completion_with_tools.

59, replace the nested MagicMock mocks for chat_completion_with_tools with an
actual ChatCompletion object. First, import ChatCompletion, Choice, and
ChatCompletionMessage from praisonaiagents.llm.openai_client at the top of the
file. Then construct a ChatCompletion instance with a list containing a Choice
whose message is a ChatCompletionMessage with the desired content string. Assign
this ChatCompletion instance as the return value of
mock_client_instance.chat_completion_with_tools to properly reflect the real
