PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis ❌

15697 - Not compliant

Non-compliant requirements:

• Fix all type annotation errors that Mypy finds in the Python bindings codebase
• Go through the codebase and resolve the 120 errors found in 30 files
• Update CI job to fail when Mypy encounters errors to prevent future regressions
• Improve static type checking using mypy for Python bindings

Wrong PR Content

The PR description claims to fix type annotation errors in Python bindings but only modifies ReadTheDocs configuration file with comments and formatting changes. This does not address the actual ticket requirements.

PR description mismatches actual changes

The PR description claims to fix type annotation errors in Python bindings and
modify selenium/webdriver/common/by.py, but the actual changes only update
.readthedocs.yaml with comments and formatting. This is a significant mismatch
between the stated purpose and implementation that needs to be corrected.

Examples:

py/docs/.readthedocs.yaml [1-31]
# .readthedocs.yaml
# ✅ Configuration file for building and publishing Selenium's Python API docs using Read the Docs.
# ℹ️ Reference: https://docs.readthedocs.io/en/stable/config-file/v2.html

version: 2  # ✅ YAML schema version (v2 is current as per ReadTheDocs)

  os: ubuntu-24.04  # ✅ Use Ubuntu 24.04 as build environment

  tools:

 ... (clipped 20 lines)

Solution Walkthrough:

Before:

// PR Description
Title: "Fix: [py] Fix type annotation errors"
Files Modified: selenium/webdriver/common/by.py
Changes: Updated type hints for function arguments.

// Actual Changes
- File: .readthedocs.yaml
- Content: Add comments and formatting.

After:

// PR Description
Title: "Docs: Improve .readthedocs.yaml readability"
Files Modified: py/docs/.readthedocs.yaml
Changes: Added comments and formatting to clarify build steps.

// Actual Changes
- File: .readthedocs.yaml
- Content: Add comments and formatting.
Suggestion importance[1-10]: 10

__

Why: This is a critical issue as the PR description is entirely inaccurate, describing Python type hint fixes while the code only adds comments to a YAML configuration file.

High
Possible issue
Fix incomplete cd command

The cd command at the end is incomplete and will fail. It should specify a
target directory or be removed entirely since the working directory change is
temporary within the command.

py/docs/.readthedocs.yaml [20-21]

 # ✅ Generate dynamic module listing before building the docs
-- cd py && python3 generate_api_module_listing.py && cd
+- cd py && python3 generate_api_module_listing.py
  • Apply / Chat
Suggestion importance[1-10]: 4

__

Why: The suggestion correctly identifies that the && cd part of the command is redundant because each command runs in its own shell, making the change of directory temporary.

The PR description claims to fix type annotation errors in Python bindings and
modify selenium/webdriver/common/by.py, but the actual changes only update
.readthedocs.yaml with comments. This mismatch suggests either the wrong files
were committed or the description is incorrect for this PR.

Why: This suggestion correctly identifies a critical and blocking discrepancy between the PR's stated purpose and its actual content, which must be resolved.

General
Remove emojis from comments

Remove emojis from configuration comments as they may cause encoding issues in
CI/CD environments and are not standard practice in YAML configuration files.
Use plain text for better compatibility.

Why: This is a stylistic suggestion that contradicts the PR's intent, which is to add comments and emojis for enhanced readability.

Remove inline configuration comments

Remove inline comments with emojis from configuration values as they can
interfere with YAML parsing and are unnecessary for simple key-value pairs.

sections to maintain clean, standard YAML formatting and avoid potential parsing
issues.
