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 test coverage for PraisonAI's sequential tool calling feature. It establishes a dedicated and comprehensive test suite, complete with a flexible mocking infrastructure, to thoroughly verify the agent's ability to execute multiple tools in sequence, manage context, handle diverse LLM response formats, and ensure robust error handling across various AI providers.
Highlights
- New Test Suite: I've added a new comprehensive test file,
test_sequential_tool_calling.py, specifically designed to validate the sequential tool calling functionality within PraisonAI agents. - Mocking Infrastructure: The PR introduces a
MockLLMResponsehelper class, which provides a robust way to simulate various LLM behaviors, including generating tool calls, text responses, and streaming outputs, enabling realistic testing without actual LLM calls. - Broad Test Coverage: The new tests cover a wide array of sequential tool calling scenarios, including basic multi-tool execution, handling tool dependencies, error handling (e.g., division by zero), streaming responses, processing complex argument structures, and scenarios where multiple tool calls are returned in a single LLM response.
- Multi-Provider Compatibility: Tests are included to ensure that sequential tool calling works correctly across different LLM providers, such as OpenAI, Gemini, Ollama, and Anthropic, verifying compatibility with their respective response formats.

Code Review
This pull request introduces comprehensive mock tests for sequential tool calling. The tests cover various scenarios, including different providers, streaming, and error handling. Suggestions include using standard package installation practices, simplifying mock response generation, improving test structure, and clarifying the success condition in the retry test.

The try...except block in test_sequential_tool_retry_on_error creates an ambiguous success condition. Refactor the test to assert the successful outcome after a retry, clarifying the test's purpose.

Modifying sys.path with a relative path can lead to inconsistent behavior across different environments. Consider setting up the project as a proper Python package and installing it in editable mode using pip install -e ..

The MockLLMResponse class uses nested classes, which adds verbosity. Using unittest.mock.MagicMock can simplify the mock object creation.

The helper classes OllamaToolCall, OllamaMessage, OllamaChoice, and OllamaResponse are defined inside the test_sequential_with_ollama method. Moving these class definitions outside the test method improves code organization and readability.

The test_sequential_with_different_providers test uses the same generic MockLLMResponse for all providers. Consider creating provider-specific mock responses to verify provider-specific response parsing logic.

Bug: Mock Response Type Inconsistency
The streaming_side_effect function in test_sequential_with_streaming returns inconsistent types: a list of MockChunk objects for streaming responses, but single MockResponse objects for tool call responses. This type mismatch can cause runtime errors or unpredictable behavior when the litellm.completion mock is invoked.

Lines 259 to 301 in 61d660d
Bug: Test Ambiguity Causes Retry Mechanism Misreporting
The test_sequential_tool_retry_on_error test contains contradictory logic that renders it ineffective. Its try-except block is structured to pass if the retry mechanism successfully recovers (by asserting the result), but also passes if the initial error propagates (by asserting the specific exception). This ambiguous behavior means the test provides a false positive for retry functionality, as it passes regardless of whether the retry works or not.

Test always passes regardless of retry implementation
Low Severity
The test_sequential_tool_retry_on_error test is designed to pass regardless of whether retry logic exists in the agent. It catches the exception and asserts on the error message if retry fails, or asserts on the result if retry succeeds. This means the test can never fail and doesn't actually verify any behavior - it provides no regression protection. A test that always passes is effectively dead code that provides false confidence in test coverage.

In `@src/praisonai/tests/unit/test_sequential_tool_calling.py`:
- Around line 16-20: The test currently swallows import problems by catching
ImportError and calling pytest.skip; instead cause the suite to fail fast so CI
surfaces missing deps—either remove the try/except so an ImportError from the
imports of Agent or LLM propagates, or replace pytest.skip(...) with
pytest.fail(f"Missing required modules: {e}") in the except block; update the
import block referencing Agent, LLM and pytest.skip accordingly so missing core
imports fail the test rather than silently skipping it.
- Around line 260-301: The streaming_side_effect in
test_sequential_with_streaming is returning non-iterable
MockLLMResponse.create_tool_call_response() objects for intermediate tool calls
which breaks the streaming parser; update streaming_side_effect (or add a
helper) to return streaming-compatible iterables for tool calls by converting
the tool-call message into a sequence of chunks matching the streaming format
(i.e., an iterable whose items expose .choices[0].delta with the tool call
metadata) instead of a single non-iterable MockResponse, so both intermediate
tool calls and the final response use the same streaming-compatible structure
used by MockLLMResponse.create_streaming_response().
- Around line 575-612: The test currently accepts both success and failure so it
doesn't validate retry behavior; either implement retry support in Agent's LLM
call path or remove/adjust the test. To implement retries: add retry logic
honoring Agent.max_retry_limit inside the Agent._chat_completion (or the method
that calls the LLM), have the mock-driven side_effect increment attempts and
raise until retries exhausted, and expose/consume max_retry_limit on Agent so
the test can set it (e.g., Agent(..., max_retry_limit=2)) and then assert the
side effect was retried (check attempt count or that the transient error is
recovered and final response contains "IBM" or "100"). If you prefer not to
implement retries, delete this test or change it to assert that transient errors
propagate and update docs to state retries are not auto-applied.
- Around line 23-95: The mocks only expose attributes but llm.py uses dict-style
access (e.g., response["choices"][0]["message"]["content"]); add __getitem__
methods to the mock classes so they support both attribute and subscript access:
implement __getitem__ on MockResponse to return attributes like "choices", on
MockChoice to return "message" (or "delta" for streaming choice), on MockMessage
to return "content" and "tool_calls", on MockToolCall to return "function" and
"id", and on MockChunk/MockDelta to return "choices" and "delta" respectively;
have each __getitem__ delegate to getattr(self, key) (or raise KeyError for
unknown keys) so existing code using MockResponse, MockChoice, MockMessage,
MockToolCall, MockChunk, and MockDelta works with both dot and dict-style
access.
🧹 Nitpick comments (1)

503-540: Avoid brittle assertions on exact message counts.Exact counts can change when system/tool messages shift across providers. Prefer asserting monotonic growth or the presence of tool-role messages.
🔧 More robust assertion

Avoid silently skipping the suite on core import errors.
Skipping here hides misconfigurations and makes CI pass without running these tests. Prefer failing fast so missing dependencies are visible.

Add dict-style access support to mock response objects.
The mocks expose attributes only (e.g., mock.choices), but llm.py accesses responses using dict-style syntax (e.g., response["choices"][0]["message"]["content"] at lines 797, 809, 701 in llm.py). This will raise 'MockResponse' object is not subscriptable' errors.
Implement __getitem__ on the mock classes to support both attribute and subscript access patterns.

Return streaming-compatible response structure for tool calls when stream=True.
Lines 271-275 return create_tool_call_response() (non-iterable) but the streaming parser iterates responses with for chunk in response. This triggers TypeError: 'MockResponse' object is not iterable.
For sequential tool calling with streaming, all intermediate responses must return iterables with the .choices[0].delta structure, not .message. The final text response at line 278 correctly uses create_streaming_response().
Either wrap tool-call responses in a streaming structure or create a helper method that converts tool calls into streaming-compatible delta chunks (similar to how create_streaming_response() builds chunks from content).

Test is ambiguous and doesn't validate retry behavior.
The test accepts both success and failure paths, so it passes whether retry logic exists or not and won't catch regressions. However, note that max_retry_limit is defined in the Agent API but is not currently implemented for LLM calls—only for guardrail validation.
To fix this test, either:
- Implement retry logic in
_chat_completionand configuremax_retry_limiton the Agent, then assert the retry count, or - If retry logic shouldn't be auto-applied, remove this test and clarify retry expectations in documentation.
Example (if implementing retries)
agent = Agent(
instructions="You are a helpful assistant.",
llm="gpt-4",
- tools=[get_stock_price]
+ tools=[get_stock_price],
+ max_retry_limit=2
)
- # This might fail if retry logic isn't implemented
- try:
- result = agent.chat("Get IBM stock price")
- # If retry logic exists, we should get a result
- assert "100" in result or "IBM" in result
- except Exception as e:
- # If no retry logic, we expect the exception
- assert "Transient API error" in str(e)
+ result = agent.chat("Get IBM stock price")
+ assert attempt == 2 # Verify retry occurred
+ assert "100" in result or "IBM" in result🧰 Tools

612, The test currently accepts both success and failure so it doesn't validate
retry behavior; either implement retry support in Agent's LLM call path or
remove/adjust the test. To implement retries: add retry logic honoring
Agent.max_retry_limit inside the Agent._chat_completion (or the method that
calls the LLM), have the mock-driven side_effect increment attempts and raise
until retries exhausted, and expose/consume max_retry_limit on Agent so the test
can set it (e.g., Agent(..., max_retry_limit=2)) and then assert the side effect
was retried (check attempt count or that the transient error is recovered and
final response contains "IBM" or "100"). If you prefer not to implement retries,
delete this test or change it to assert that transient errors propagate and
update docs to state retries are not auto-applied.

Fixes #847
This PR adds comprehensive mock tests for sequential tool calling functionality in PraisonAI.
Changes
test_sequential_tool_calling.pywith 11 test methodsGenerated with Claude Code
Note
Low Risk
Test-only change that adds mocked coverage without modifying runtime logic; main risk is brittleness/false confidence if provider response formats diverge from real APIs.
Overview
Adds a new
test_sequential_tool_calling.pyunit test suite that fully mockslitellm.completionto validate sequential tool calling behavior throughAgent.chat.The tests cover multi-step tool chaining (2–3 tools), dependency on prior tool outputs, streaming flows, multiple tool calls returned in a single assistant message, provider/model response-format variations (OpenAI/Gemini/Ollama/Anthropic), context accumulation across turns, complex/nested tool arguments, and basic error/recovery + a transient-failure retry expectation.
