CI Failure Feedback 🧐

(Checks updated until commit 2f746cc)

Action: build-and-test

Failed stage: Build dev docker [❌]

Failure summary: The action failed due to a dependency conflict during the installation of Python packages: The package pr-agent version 0.2.4 requires pytest version 7.4.0. The package pytest-asyncio version 0.24.0 requires pytest to be between versions 8.2 and 9. These conflicting requirements for pytest make it impossible to resolve dependencies, leading to a failure in the package installation process.

✨ CI feedback usage guide:

---

The CI feedback tool (/checks) automatically triggers when a PR has a failed check.
The tool analyzes the failed checks and provides several feedbacks:

• Failed stage
• Failed test name
• Failure summary
• Relevant error logs

In addition to being automatically triggered, the tool can also be invoked manually by commenting on a PR:

/checks "https://github.com/{repo_name}/actions/runs/{run_number}/job/{job_number}"

where {repo_name} is the name of the repository, {run_number} is the run number of the failed check, and {job_number} is the job number of the failed check.

Configuration options

• enable_auto_checks_feedback - if set to true, the tool will automatically provide feedback when a check is failed. Default is true.
• excluded_checks_list - a list of checks to exclude from the feedback, for example: ["check1", "check2"]. Default is an empty list.
• enable_help_text - if set to true, the tool will provide a help message with the feedback. Default is true.
• persistent_comment - if set to true, the tool will overwrite a previous checks comment with the new feedback. Default is true.
• final_update_message - if persistent_comment is true and updating a previous checks message, the tool will also create a new message: "Persistent checks updated to latest commit". Default is true.

See more information about the checks tool in the docs.

/help how to do a custom label in PR Agent?

[qodo-merge-pro-for-open-source]

Question:

how to do a custom label in PR Agent?

Answer:

There are 3 ways to enable custom labels in Qodo Merge (PR-Agent):

1. CLI (local configuration file):
   Edit the custom_labels.toml file with your custom labels and their descriptions.

2. Repo configuration file:
   Add custom labels configuration to the local .pr_agent.toml file:

[config]
enable_custom_labels=true

[custom_labels."Custom Label Name"] 
description = "Description of when AI should suggest this label"

3. Repo's labels page (Pro feature):

• Go to repo's labels page (GitHub/GitLab)
• Add custom labels with description prefixed by "pr_agent:"
• Format: Label name + "pr_agent: Description of when AI should suggest this label"

The custom labels will be used by both the dedicated /generate_labels tool and the describe tool.

/ask does it make sense that the test_pr_help_message_run_no_openai_key() doesn't have asserts?

[qodo-merge-pro-for-open-source]

Ask❓

does it make sense that the test_pr_help_message_run_no_openai_key() doesn't have asserts?

Answer:

Yes, it makes sense that the test_pr_help_message_run_no_openai_key() function doesn't have traditional asserts. Instead, it uses mock_git_provider.publish_comment.assert_called_once_with(...) to verify that the expected behavior occurs when there is no OpenAI API key. This is a common pattern in unit tests that involve mocking, where the test checks that certain methods are called with expected arguments, rather than asserting on return values or state changes. This approach is appropriate for testing interactions with mocked objects.

Reasoning Step:

---

Okay, I'm looking at the PR diff provided. The main changes are in two files: 'tests/unittest/test_pr_help_message.py' and 'requirements.txt'.

First, in the test file, there are several test cases added for the PRHelpMessage class and the extract_header function. The tests seem to cover initialization, running without an OpenAI key, and extracting headers from snippets. The code looks well-structured, using pytest fixtures and async marks where necessary. I don't see any obvious bugs or issues in the test cases themselves.

Next, looking at the requirements.txt file, the addition of 'pytest-asyncio==0.21.0' is noted. This makes sense because the test file uses async functions, so the pytest-asyncio plugin is necessary to run them correctly. Without this, the async tests might not execute properly, leading to test failures or skipped tests.

I don't see any other changes that would introduce critical bugs. The tests are comprehensive, and the added dependency is appropriate. Therefore, there are no critical issues to address in this PR.

Learned best practice	Replace hardcoded test strings with variables for better maintainability Extract hardcoded strings used in test assertions into variables at the top of the test file for better maintainability and consistency. tests/unittest/test_pr_help_message.py [11-19] -assert extract_header(snippet) == "#test" -assert extract_header(snippet) == "#first" +TEST_HEADER = "#test" +FIRST_HEADER = "#first" +assert extract_header(snippet) == TEST_HEADER +assert extract_header(snippet) == FIRST_HEADER + Apply this suggestion	6

Category	Suggestion	Score
General	Verify mock function calls Add assertions to verify that the mock methods were called with expected arguments. Currently only checking the return values. tests/unittest/test_pr_help_message.py [34-43] mock_get_provider.return_value = mock_git_provider mock_get_settings.return_value.get.return_value = 5 mock_ai_handler = Mock() # Test initialization with question help_msg = PRHelpMessage("test_url", args=["test", "question"], ai_handler=mock_ai_handler) assert help_msg.question_str == "test question" assert help_msg.git_provider == mock_git_provider assert help_msg.num_retrieved_snippets == 5 +mock_get_provider.assert_called_once_with("test_url") +mock_get_settings.return_value.get.assert_called_once_with("num_code_snippets") Suggestion importance[1-10]: 7 Why: The suggestion improves test quality by verifying not just return values but also that mock functions were called correctly with expected arguments, which helps catch potential implementation changes that could break expected behavior.	7
Learned best practice	Add test cases for edge cases and null input validation to ensure robust error handling The extract_header() test cases should include validation for edge cases like None input and empty strings. Add test cases to verify the function handles these scenarios gracefully. tests/unittest/test_pr_help_message.py [8-19] def test_extract_header(): # Test with valid header snippet = "Header 1: Test\n===Snippet content===" assert extract_header(snippet) == "#test" # Test with no header snippet = "Some content\n===Snippet content===" assert extract_header(snippet) == "" - # Test with multiple headers (should take first header in reversed list) + # Test with multiple headers snippet = "Header 1: First\nHeader 2: Last\n===Snippet content===" assert extract_header(snippet) == "#first" + + # Test edge cases + assert extract_header(None) == "" + assert extract_header("") == "" + assert extract_header(" ") == ""	6

However, it does not address the existing functionality mentioned in the comment.	3

Possible issue	Enhance error handling for missing OpenAI API key scenarios Add error handling in test_pr_help_message_run_no_openai_key to manage cases where the OpenAI API key is not provided, preventing runtime errors. tests/unittest/test_pr_help_message.py [62] -await help_msg.run() +try: + await help_msg.run() +except KeyError: + # Handle missing OpenAI key Suggestion importance[1-10]: 7 Why: This suggestion is valuable as it addresses potential runtime errors due to missing configuration, enhancing the robustness and reliability of the test.	7
