Summary of Changes

Hello, 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 introduces infrastructure for code coverage tracking within the project. By adding the necessary dependency and configuring the coverage tool, the team can now measure and analyze test execution paths, which is essential for maintaining high code quality and identifying untested areas of the codebase.

Highlights

• Dependency Update: Added the 'coverage' package to requirements-dev.txt to support code coverage analysis.
• Configuration Setup: Introduced a new '.coveragerc' configuration file in the tests directory to define coverage collection parameters, including concurrency settings and file inclusion/exclusion rules.

New Features

🧠 You can now enable Memory (public preview) to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

Suggested PR Title:

[Test][Feature] Add coverage configuration and dependency

Suggested PR Summary:

### What this PR does / why we need it?
This PR adds the `coverage` package to `requirements-dev.txt` and introduces a `.coveragerc` configuration file to enable code coverage tracking for the `vllm_ascend` module.

Feedback:
- The `data_file` path in `tests/coveragerc` is hardcoded to a specific user's directory (`/mnt/share/s00837289/covdata/coverage`), which will cause failures in other environments or CI. It should be changed to a relative path.
- The `include` path `/vllm_ascend/*` is absolute and should be changed to a relative pattern like `vllm_ascend/*` to ensure proper matching.

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
No tests were added as this is a configuration change.

[gemini-code-assist]

The data_file path is hardcoded to a specific user's directory (/mnt/share/s00837289/covdata/coverage). This will cause coverage collection to fail on other environments or CI systems where this path does not exist or is not writable. Please use a relative path or a generic directory to ensure portability.

data_file = .coverage_data/coverage

[gemini-code-assist]

The include path /vllm_ascend/* specifies an absolute path starting from the root directory. This will likely fail to match the source files unless they are located at the filesystem root. Consider using a relative path pattern like vllm_ascend/* instead.

    vllm_ascend/*
